Exploring TIM3 Inhibitors as a Promising Partner for Immune Checkpoint Inhibitors

T cell immunoglobulin mucin-3 (TIM3) was first discovered in 2002 and is a member of the TIM family of immunomodulatory proteins. TIM3 has attracted much attention because it is related to the regulation of autoimmunity and immune response in cancer. In recent years, the development of TIM3 inhibitors is also steadily proceeding, with a view to solving the problems of low response rate and drug resistance of existing immune checkpoint inhibitors.

Immunosuppressive drugs effect of TIM3 in tumor microenvironment

TIM3 was originally thought to be a receptor expressed on CD4+ and CD8+ T cells that produce interferon-γ, and TIM3 expression was subsequently found in many other types of cells, including regulatory (Treg) T cells , Myeloid cells, natural killer cells and mast cells. Therefore, TIM3 targeted therapy may modulate the immune response by acting on multiple cell types.

TIM3 can inhibit T helper cells (Th1 and Th17) in the tumor microenvironment, induce CD8+ T cell depletion, promote Treg cells to become a highly immunosuppressed cell population, and promote bone marrow-derived cells with powerful T cell immune response suppression functions. A large number of inhibitory cells (MDSCs) expand, promote innate immunosuppression, and tumor immune escape.

The specific role of TIM3 in non-T cell leukocytes is summarized in the following table:

Advances in clinical research of TIM3 block therapy

In the preclinical model, the combined blocking therapy of TIM3 and PD1 is superior to monotherapy, which can improve the anti-tumor T cell response of patients with advanced cancer and can lead to tumor regression.

Recently, a number of clinical trials of TIM3 blocking therapy alone or in combination with other therapies have been carried out (one of which is a clinical trial of bispecific antibodies designed for PD-1 and TIM3), involving many types of tumors. Advanced malignant tumors, such as acute myeloid leukemia (AML), lymphoma, liver cancer, and non-small cell lung cancer, are summarized in the following figure:

Ongoing and planned clinical trials of anti-TIM3 drugs
(Picture from reference 2)

TSR-022 is the first anti-TIM3 drug to publish experimental data. This is a humanized anti-TIM3 IgG4 antibody developed by Tesaro. Monotherapy with TSR-022 resulted in 31 patients with stable disease (SD), 1 patient with leiomyosarcoma had partial response (PR), and no dose-limiting toxicity was observed.

The effectiveness of TSR-022 single drug has opened the door to hope for subsequent combination therapy with PD-1 antibody. In 202 cases of non-small cell lung cancer patients refractory to PD-1/PD-L1 antibody, when used in combination with a fixed dose of TSR-042 (a PD-1 antibody), as the dose of TSR-022 increased Its clinical activity is also increasing (represented in the proportion of SD or PR patients). Most importantly, this combination therapy is also well tolerated, with no dose-limiting toxicity observed.

Recently, Eli Lilly's TIM3 blocking antibody LY3321367 and Novartis' anti-TIM3 antibody MGB453 have been reported to have successfully passed Phase I clinical trials. Consistent with the preclinical model, the combined blocking therapy of TIM3 and PD1 is superior to monotherapy.

These existing data indicate that TIM3 is indeed a "checkpoint" receptor. Inhibiting TIM3 can enhance the anti-tumor effect of PD-1 blockers, and is expected to become the next strength partner of PD-1 block therapy for tumor patients. Bring more treatment options and hope. I also hope that these ongoing clinical trials will bring us more good news.

Diagnosis and Etiology of Growth Hormone Deficiency Syndrome

Growth hormone deficiency (GHD) is due to the anterior pituitary synthesis and secretion of human growth hormone (growthhormone, GH) partial or complete lack of, or due to structural abnormalities, such as receptor defects caused by the growth and development of the disorder.Its height is normal, healthy children of the same age, and sex growth curve under the third percentile or less than two standard deviations, short stature (shortstature) standard.With its incidence of 20/10 ~ 25/10. [ Growth hormone synthesis, secretion and function ] Human growth hormone (hGH) is a single chain polypeptide is synthesized and secreted by the anterior pituitary cells , 191 amino acids with a molecular weight of 22KD, genes coding GHl at 17q22-24. In the blood circulation , and about 50% of growth hormone GH binding protein (GHBP) combined to form GH-GHBP complex exists. Release of human growth hormone secreted by the hypothalamus two neurohormones that growth hormone releasing hormone (GHRH) and somatostatin (somatostatin, SRIH or GHIH) regulation. GHRH is a 44 amino acid residues containing a polypeptide , promote the synthesis and secretion of pituitary GH secreting cells GH; SRIH cyclic peptide structure 14 depress the secretion of a variety of GH secretagogues . In the interaction between these two pituitary peptide pulsed way to release hGH, and the central nervous system through dopamine, 5 - serotonin and norepinephrine neurotransmitters regulate the secretion of hypothalamic GHRH and SRIH . HGH can play a direct role in cell biological effects , but most of its functions must like growth factor (insutin-likegrowthfactor, IGF) mediated by insulin. The human body has two IGF, IGF-I and that IGF-Ⅱ. IGF-I is a single chain polypeptide having a molecular weight 7.5KD , which gene is located 12q22-24.1, secreting cells are widely present in the liver, kidney, lung, heart, intestine and brain tissues , mainly by the synthetic hGH adjustment , and also age, nutrition and hormone levels and other factors. Synthesis of IGF-I secretion mostly in an autocrine manner or neighbor to play its role in promoting growth . The role of IGF-Ⅱ has not been elucidated . Circulating hGH concentration and IGF- workers can feedback regulation of pituitary hGH secretion , inhibit the secretion of GHRH or indirect effects on the hypothalamus , and stimulate SRIH secretion. Under the combined effect of various factors , hGH secretion was pulsatile nature , occur about every two hours a peak high secretion after falling asleep at night , and with the depth of sleep ; daytime fasting and after exercise occasionally peak. Babies born high serum GH levels , secretion rhythm is not yet mature , so sleep - wake cycle GH levels rarely fluctuate. 2 to 3 weeks after birth , serum GH concentrations began to decrease , the secretion rhythm began to appear after birth two months. Children of daily GH secretion than adults, higher secretion at puberty . The basic function of serono serostim hGH is to promote growth in vivo is also an important regulator of metabolic pathways regulate many metabolic substances . ① growth-promoting effects: the promotion of human cells in various tissues increases and proliferation, bone, muscle and organ growth and development of each system , bone growth that causes the body to grow taller. ② promote metabolic effects : on the basis of growth-promoting effect of hGH is anabolic , can promote protein synthesis and amino acid transport and uptake ; promote glycogen breakdown and reduce glucose utilization , reduce the sensitivity of cells to insulin , so hyperglycemia ; promoting fat tissue decomposition and oxidation of free fatty acids during ketogenic ; promote chondrocyte proliferation and synthesis of bone matrix contains collagen and sulfated glycosaminoglycans. [ Cause ] Growth hormone deficiency is due to inadequate secretion of hGH , for the following reasons : 1 . Idiopathic ( primary ) of such children in the hypothalamus , pituitary no obvious lesions, but the lack of GH secretion , and its cause is unknown. Which due to neurotransmitters - neurohormonal pathways function defects , leading to inadequate secretion of GHRH short stature caused by hormone called neuroendocrine dysfunction (GHND). Since GHD hypothalamic dysfunction caused by pituitary insufficiency leading to much higher than those of many. About 5% of children with GHD caused by genetic factors , known as hereditary human growth hormone deficiency (HGHD). Human growth hormone gene cluster is encoded by the gene GHl (GH-N) and CSHPl, CSHl, GH2, CSH2 about 55Kbp genes composed of DNA strands . Due to the lack of GHl gene called simple growth hormone deficiency (1GHD), and by the pituitary transcription factor Pit-1 caused by the defect , the clinical manifestations of multiple pituitary hormone deficiency , known as the Joint pituitary hormone deficiency (CPHD) . IGHD according to the mode of inheritance is divided into I (AR), Ⅱ (AD), Ⅲ (X linked ) III . In addition , there are a small number of children with short stature due to GH molecular structural abnormalities , GH receptor deficiency (Laron syndrome ) or IGF receptor-deficient ( African Pygmy people ) caused similar clinical symptoms and GHD , but showed resistance to GH or IGF- I resist , serum GH levels are not reduced or increased but is relatively rare genetic disease. 2 . Organic ( acquired ) secondary to hypothalamic , pituitary or other intracranial tumors , infection, cell infiltration, radiation injury and head trauma , including birth trauma is the main cause of domestic GHD 's . In addition, pituitary abnormalities, such as agenesis , hypoplasia or empty sella , some accompanied by visual septum hypoplasia (Septo-opticdysplasia), cleft lip , cleft palate and other deformities , can cause the synthesis and secretion of growth hormone disorders . 3 . Temporary growth delay puberty physical , social psychological growth inhibition, primary hypothyroidism , etc. can cause temporary GH secretion dysfunction in external adverse factors eliminate or primary disease can be restored to normal after treatment. [ Clinical manifestations ] Idiopathic growth hormone deficiency is more common in boys , male: female = 3:1. When the height and weight of children born were normal , appeared to slow down the growth rate after 1 year of age , height, weight behind the more serious lower than the height is lower than the same age , same sex normal healthy child growth curve of the third percentile or less ( or less than two standard deviations ) , height annual growth rate of less than 4cm, mental development is normal. Children with head round, childish face , chubby face , delicate skin , hair, slim , poor jaw and chin growth, delayed tooth eruption and irregular arrangement . Although the growth of children behind, but well-proportioned body parts , in line with their actual age . Skeletal retardation, bone age lagged behind the actual age of 2 years old, the same age but its height . Epiphyseal fusion of late. Most of delayed puberty . Part of the growth hormone deficiency in children accompanied by one or more other pituitary hormone deficiency , growth retardation in addition to these children , there are other associated symptoms : accompanied by adrenocorticotropic hormone (ACTH) deficiency is easy to hypoglycemia ; with thyroid stimulating hormone (TSH) deficiency may have loss of appetite, do not love activities mild thyroid deficiency symptoms ; gonadotropin deficiency associated with gonadal dysgenesis , appear small penis ( ie straighten penis length of less than 2.5cm ) , the adolescent still no sexual organs and secondary sexual characteristics and so on. Organic growth hormone deficiency can occur at any age , in which the cause of perinatal abnormalities who often accompanied by diabetes insipidus -like . Alarming is intracranial tumors are more than a headache, vomiting, visual field defects , increased intracranial pressure and optic nerve oppressed signs and symptoms. [ Laboratory ] 1 . Growth hormone stimulation test growth hormone deficiency diagnosis relies GH determination . Normal serum GH value is very low , and showed pulsatile secretion , affected by various factors , the random blood test for the diagnosis of GH blood does not make sense , but if any blood GH levels were significantly higher than normal (> 10 ~ g / L) , can be ruled out GHD. Therefore , GHD children suspected GH stimulation test must be done to determine the function of the pituitary GH secretion . Determination of GH secretion function tests commonly used are shown in Table 17-1. Department of Physiology test screening test , drug test for the confirmatory test . Generally believed that during the test , GH peak <10ug / L is not normal secretory function . GH peak <5ug / L, the complete lack of GH ; GH peak 5 ~ 10ug / L, a lack of GH section. Due to various GH stimulation test have certain limitations , be two or more drugs to stimulate the test results are not normal, be diagnosed with GHD. More generally choose clonidine or insulin plus levodopa test . For younger children , especially when fasting insulin hypoglycemia were to be especially careful , because it can lead to hypoglycemia, seizures and other serious reactions. In addition, housekeeping is the difference between the lesion in the hypothalamus or pituitary GHRH stimulation test to be done . 17-1 secretion of growth hormone blood test Test Methods Table physiological one time . Sports fasting for 4 - 8 hours after strenuous activity 15 - 20 minutes after the start activity 20 - 40 minutes 2 . When night sleep after sleep EEG monitoring with Ⅲ ~ Ⅳ sleep drugs to stimulate a . Insulin 0.05--0.1U/kg, intravenous 0,15,30,60,90,120 minutes to measure blood sugar , GH, 2. Arginine 0.05/kg, paired with water for injection 5% to 10 % solution , finished 30 minutes 0,30,60,90,120 min infusion measured GH3. Clonidine 0.004mg/kg, 1 oral ditto 4. Levodopa 10mg/kg, 1 oral ditto 2 . The 24h blood GH normal GH secretion spectroscopy very different peak values ​​of the base , GH secretion 24h to compare accurately reflect the in vivo GH secretion , especially for children GHND their secretion of GH stimulation tests for drug normal , but the amount is less than 24h secretion , GH peak during sleep at night is also low . However, this method tedious , blood more often, difficult for patients to accept. 3 . Insulin-like growth factor (1GF-1) measured IGF-1 mainly in the form of protein binding (1GF-BPs) is present in the blood circulation , which IGF-BP3 mainly ( over 95%), IGF-BP3 have transport and regulation IGF-1 function , and its synthesis is also regulated by GH-IGF axis , so IGF-1 and IGFBP3 are indicators of the axis detection function . Both GH secretion patterns with different , non- pulsatile secretion was less fluctuation in day and night , so very stable , its concentration is very low in children under 5 years of age , and the age and developmental changes in the larger , reached the peak of puberty , girls than men children reached a peak two years earlier . It is generally available as a 5 -year-old children before puberty GHD screening to detect . The index has some limitations , but also by nutritional status, degree of development and the impact of thyroid functional status and other factors, should determine the outcome attention. 4 . Other laboratory examinations (1) X -ray examination : common pieces left wrist metacarpal and phalangeal bone age assessment . GHD in children 2 years of age or bone age lags behind the actual age of 2 years and older . (2) CT or MRI : children have been diagnosed with GHD choose cranial CT or MRI needed to understand the hypothalamic - pituitary or without organic disease, especially cancer is important. 5. Other endocrine examination GHD once established, must check the hypothalamic - pituitary axis other features. Clinical manifestations can choose measured according TSH, Ding 4 or thyrotropin-releasing hormone (TRH) stimulation test and luteinizing hormone releasing hormone (LHRH) stimulation test to determine the hypothalamic - pituitary - thyroid axis and gonadal axis function . [ Diagnosis and differential diagnosis ] 1 . The diagnosis diagnosis based on: ① short stature, tall behind the same age , and the third percentile for children of the same sex to normal ; ② slow growth, the growth rate of <4cm / years ; ③ behind the actual bone age more than 2 years of age ; ④ GH stimulation test shows partial or complete lack of GH ; ⑤ normal intelligence , commensurate with age ; ⑥ rule out other diseases affected. 2 . The reason behind the growth differential diagnosis caused a lot , to be identified with GHD are: ( 1 ) familial short stature : tall parents are short, tall children often left in the third percentile , but its annual growth rate of more than 4cm / years , bone age and age-appropriate , smart and normal sexual development . ( 2 ) physical sexual delayed puberty : the temporary GHD in the most representative of this disease , is a variation of normal development , more common in boys. Puberty began to develop later time than normal children 3-5 years of slow growth before puberty , bone age corresponding backward, but the height is consistent with bone age after puberty its final height is normal. One of the parents often have a history of delayed puberty . ( 3 ) congenital ovarian dysgenesis (Turner syndrome ) : a girl with short stature should be considered disease. The clinical features of Turner syndrome are: short stature, no development of secondary sexual characteristics , short neck, webbed neck , elbow valgus, the low hairline . A typical Turner syndrome and GHD difficult to distinguish , but the arm of chromosome mosaicism or equal to those caused by atypical symptoms due , karyotype analysis should be conducted to identify . ( 4 ) congenital hypothyroidism : the disease except for growth retardation , basal metabolic rate, bone age lagged behind , there are mental retardation , it is difficult to distinguish with GHD . But some obvious symptoms of late-onset cases , reduce the need to rely on blood T4 , TSH increased identification. ( 5 ) skeletal disorders : a variety of bone, cartilage hypoplasia , have a special face and body , with optional bone X-ray examination to identify. ( 6 ) the growth of other endocrine and metabolic diseases caused by backward : congenital adrenal hyperplasia , precocious puberty, Cushing's syndrome , each with its clinical manifestations mucopolysaccharidosis , glycogen storage disease , is easy to identify. [ Treatment ] 1. The growth hormone gene recombinant human growth hormone (rhGH) recombinationhGH, replacement therapy has been widely used, which are largely 0.1 U/kg;Daily subcutaneous injection before sleeping, 6-7 times a week.Treatment should be continued until the epiphyseal healing.Treatment age is smaller, the better the results, the effect is best, in the first year annual growth can reach more than 10 cm, after growth rate gradually decreases.Can appear in the process of treatment with rhGH thyroxine deficiency, we must monitor thyroid function, if there is a lack of appropriate and treated with thyroxine and at the same time. RhGH treatment side effects are less, basically have: (1) local injection redness, associated with rhGH preparation insufficient purity as well as individual reaction, can be disappeared after drug withdrawal;(2) a few months after injection of antibodies, but had no significant effect on the growth effect;(3) a rare side effects are temporary papillary edema, intracranial pressure, etc.;(4) in addition to study found that increasing the incidence of the epiphyseal sliding out and necrosis of the femoral head, but the risk is relatively low. Malignant tumor or potential tumor progression, severe diabetic patients disabled rhGH. 2. The growth hormone releasing hormone (GHRH) Are now known to many GH lacks subordinate the thalamus, the application of GHRH can work, has good curative effect to the GHND, but lack of pituitary GH is invalid.Average daily dosage of 8 ~ t ~ 30 g/kg, every day sooner or later one subcutaneously or 24 h continuous subcutaneous micro pump injection. 3. Oral sex hormone of anabolic steroids are (1) fluoride hydroxyl methyl testosterone (Fluoxymesterlone) 2.5 mg/m2 per day, (2) hydrogen oxygen a dragon (Oxandvolone) 0.1 0.25 mg/kg every day, and (3) pyrazole methyl hydrogen dragon 0.05 mg/kg per day, are the derivatives of androgen, its synthetic metabolism is strong, the role of androgen is weak, has accelerated skeletal maturity and masculine side effects occur, reason should be the strict observation of bone development.Benzyl propionate nandrolone (Durabolin) has been less application. At the same time with GHD of gonad axis dysfunction children at the age of 12 the bone age to start treatment with sex hormone and male long-term heptanoic acid injectable testosterone 25 mg, once a month, 25 mg per 3 month, until a month l00mg;Women can use ethinylestradiol 1 ~ 2 ug/day, or pregnant mare estrone (Joshua) since 0.3 mg daily discretionary increase gradually, at the same time to monitor bone age

Evaluating the Effectiveness of Growth Hormone Injections

Typically, growth hormone injection testing is used to identify GH deficiency in the body, as well as assessing pituitary gland condition. Furthermore, it can detect when there’s excess somatropin in the body, and is also used to diagnose and examine the treatment of gigantism and acromegaly. The procedure is usually done as a follow-up to other pituitary hormone test results.
Nevertheless, since growth hormone is naturally released in pulses by the pituitary gland, a single blood-level measurement may not be enough to make any clinical diagnosis. Therefore, most experts prefer testing for suppression or stimulation of the substance instead since these have more meaningful results.
I. GH Stimulation Tests
They help to diagnose somatropin deficiency and hypopituitarism. For the initial stimulation test, a blood sample is taken after the person has fasted for about 10-12hrs. Thereafter, under close supervision by a physician they would be given an injection that will normally stimulate the release of growth hormone from pituitary gland.
Next, blood samples would be taken at specific time intervals and somatropin levels tested in each stage to determine whether the pituitary gland was triggered to release the expected amounts of GH. For this process, the most commonly applied stimulant is arginine, though others that may also be used are glucagon and clonidine. Additionally, since regular exercise can cause a shift in GH levels, it can also be used as a stimulant for the release of this hormone.
To assess whether the injection has worked, the physician will determine whether insulin-like growth factor-1 (IGF-1) has been produced by the body. This hormone is responsible for mediating the effects of GH, as well as promoting normal tissue and bone growth and development. Nevertheless, unlike growth-hormone its level is usually stable throughout the day in the bloodstream. This ultimately makes IGF-1 a great indicator of average GH amounts, plus IGF-1 testing can further be used to help assess hormone deficiency and excess.
II. GH Suppression Tests
This procedure is used to diagnose excess of the compound. First, a blood sample is drawn from the individual after 10-12hrs of fasting. Then the individual is given a normal glucose solution of about 100gms to drink. Next, blood samples are taken at timed periods and tested for GH. This will help determine if the pituitary-gland has been adequately suppressed by the glucose dosage or not.
Furthermore, GH suppression test can also be used to assess treatment of the GH-producing pituitary tumor. If a growth is detected, growth hormone levels can be measured immediately after the tumor has been removed, so as to find out whether the entire growth was successfully removed or some parts remained inside the body. In this process, tests may be conducted at regular intervals for some years later in order to assess GH production, and also detect tumor recurrence if possible.
Apart from the above procedures, other blood-tests that can also be used to assess the effect of growth hormone injection and pituitary gland function are prolactin, cortisol, testosterone, cortisol and TSH amongst others. These tests are usually carried out before the GH testing, so as to ensure that basic testing parameters are normal.

The Role of Purity in Determining HGH Quality

Human growth hormone (HGH) stimulates growth and production of cells in the body. The pituitary gland in the human brain is responsible for secreting this complex hormone. It consists of 191 amino acids. HGH is the largest protein created by the pituitary gland. Pituitary gland secretes HGH throughout one's childhood. It is produced the most during the adolescent stage. The human body continues to produce HGH even after the adolescent stage. But as one grows older, the production of HGH by the pituitary gland declines. This is where HGH supplements comes in handy. The main function of this hormone is to increase muscle mass and body height. It helps to retain calcium, maintain healthy bones, reduce fat, control sugar and insulin levels and maintain immunity. Some studies even suggest it can make one look younger. Due to these benefits, there is an increasing demand for HGH supplements. And just like any other product, when there is a high demand, there is an increasing supply to meet it. While many HGH products have hit the market in recent years, a number of them should be avoided. This is why it is important to look for high quality HGH products. When quality is mentioned with regards to HGH, one very important element comes up; purity. So does purity determine the quality of HGH? Well, let us take an in-depth look at the relationship between the purity and the quality of HGH. Does purity determine the quality of HGH? The purity of an HGH product directly determines its quality. This means that an HGH product is considered to be of high quality only when it has a high purity level. HGH can be made up of either 191 amino acids (known as somatropin), or 192 amino acids (known as somatrem). The former is the real product sequence while the latter is basically an HGH mimic with comes with nasty side effects. The high purity HGH (high quality) is much costlier compared to the low purity products which are cheaply produced and have bacterial residues left over during the manufacturing process. High quality products are often bought through doctors’ prescriptions. So avoid buying your HGH supplement on the black market as most of the products are counterfeit and may have nasty side effects. Moreover, they will not deliver the kind of result that you are looking for. If you have to buy from a non-reputable source, then it is advisable to have the HGH tested in a lab. Some of the most expensive brands of HGH are products manufactured in the US. One example of such products is the Genotropin, manufactured in the US by Pfizer Inc. This high quality and high purity HGH is one of the most effective and most expensive brands in the market. There are also medium purity and medium quality HGH products such as Hygetropin manufactured in China by Zhongshan Hygene Biopharm Co., Ltd. If you are looking for cheaper brands, there are a few choices available to you such as Zomacton and Ansomone. However, most of these brands are of low quality. While such these brands may be effective, there is limited information or user feedback to back their reliability or safe use.

The Impact of HGH on Diabetes Management

HGH (Human Growth Hormone) is known as the master hormone, because it controls every growth-related body function. Low levels of this hormone can lead to aging symptoms such as muscle weakness, weight gain, low sexual drive, cardiovascular diseases and diabetes. Among its many health benefits, the HGH has been found to be useful in treating diabetes. Patients suffering from low blood sugar levels can also use HGH for energy production. But how does this work? Read on to understand how HGH levels affect diabetes. How does HGH treat diabetes? According to studies, HGH levels in the body diminish with age and this means that aging people have a higher risk of diabetes. This can be countered by inducing HGH in the body in order to regulate sugar levels. However, this diabetes treatment method should be used within a short period of time and in minimal levels. The presence of this hormone in the blood catalyzes insulin in your body, thereby facilitating absorption of glucose by body cells. An essential body hormone, insulin helps to break down glycogen into glucose. Glucose is used by the body cells to generate energy. Low insulin levels in the body causes fat cells to absorb glucose, leading to obesity and minimal energy. HGH levels in the body determine whether absorption of glucose by fat cells occurs or not. Other studies on the effects of HGH in the body have also revealed that this hormone can help in glucose metabolism as well as in reducing abdominal fats in the body. Abdominal fats affect insulin resistance and sensitivity. High cholesterol levels in the body increases the risks of contracting diabetes. Cholesterol hinders glucose respiration and instead absorbs it, leading to high levels of blood sugar and fat in the blood. HGH injections into the blood stream of the affected individual will lead to the decline of the cholesterol levels, thus reducing risks of diabetes. Another benefit of HGH to patients with diabetes is that it reduces deposits of cholesterol and fats in the body, which are responsible for insulin insensitivity. Another way in which HGH injection in the body helps in the management of diabetes is by facilitating weight loss and fat burning. HGH increases the levels of the IG-1 compound, an excretory compound produced by liver, thereby preventing movement of glucose to the body cells. Generally, insulin is released by the pancreas after meals, so as to break down carbohydrates into glucose and then carry the glucose to the body cells, and open the cell membrane to allow the glucose into the cell. The glucose is converted into fat inside the cells and then stored as an energy reservoir. To meet its energy requirements, the body will utilize the available glucose first before moving to the stored fat. Since HGH hinders the glucose supply to the cells, the body will be forced to burn the stored fats. Therefore, you burn fats without doing any exercises, or following any special diets. Remember that just like any other medication, you may experience minimal side effects if you use the wrong kind of HGH product. When HGH is used in appropriate dosage and timing, a diabetic patient can go for months without resorting to insulin injections.

Important Considerations Before Starting HGH Therapy

Human growth hormone (HGH), a naturally occurring hormone, is produced by the pituitary gland and is important for the stimulation of growth, regulation of metabolism and cell regeneration. As long as HGH is released in normal levels, it maintains the body’s delicate balance while promoting overall health. It is used medically to stimulate the growth in children making them grow faster and increasing their strength. In recent years, synthetic HGH supplements have been developed that, although controversial, may have other health benefits. HGH treatments can reduce body fat and increase muscle health and lowered levels cause a loss in energy, strength and stamina, but the cost of injecting human growth hormones was medically controlled and very expensive. The creation of synthetic HGH supplements has put HGH therapy in reach of people who could not afford the expensive and medically prescribed treatment. Synthetic human growth hormone supplements have spawned a market targeted at people who are worried about the effects of aging. Since the amount of HGH in the body decreases with age and because of the effect it has on cell growth many companies have begun marketing synthetic HGH supplements to delay the effects of aging. The original studies of human growth hormone effects showed a remarkable increase in energy, stamina and overall well-being for its subjects. Although not quite the fountain of youth that some markets claim, natural HGH did have beneficial effects on the older test subjects. It wasn’t perfect and there were side effects and some of the subject’s bodies rejected the treatment, but the therapy had a good rate of success. Body builders and athletes also use human growth hormone supplements to increase muscle mass while decreasing body fat. Higher energy levels have also been reported by users. Although all of these benefits are available through traditional athletics, HGH supplements can bypass some of the hard work and effort needed. Although the body of evidence for both the benefits and side effects of synthetic HGH supplements is not as wide or deep as needed, more information about them becomes available every day. Many of the synthetic supplements on the market have questionable ingredients and you should thoroughly research any type of therapy before using them. Synthetic HGH supplements are considerably less expensive than medically-administered human growth hormone injections. Although the Food and Drug Administration (FDA) condones the use of HGH supplements in case of pituitary gland-related deficiencies it does not endorse the use of HGH in anti-aging or athletic applications.

Key Drivers of Growth

Growth hormone can promote height growth is self-evident , but in the actual process, often there are many factors prevents body react with growth hormone. Wherein the greatest impact is thyroxine, normal amount of thyroxine is necessary to maintain healthy growth . If secretion deficiency, causes the pituitary gland to stop secreting the normal amount of growth hormone , And can prevent the body's tissues,for the hormone has been released, to respond appropriately. Conversely, if hypersecretion, will accelerate the healing of the bone marrow , the body stopped growing . You can see, thyroxine for the entire growth process always plays a limited role.Therefore, only the active cooperation of growth hormone and thyroxine, can play a role in growth in height.. Hormone is secreted by the endocrine glands , a chemicals directly into the blood . So far , about 60 hormones have been found in the body , each one has its own specific organ affected , such as the skin darkening hormones ,breasts secrete milk hormones, vascular spasm hormones . If for some reason that no secretion of hormones, it will not produce a corresponding effect . Human growth process is also a biochemical reaction in the hormone action. This slow biochemical reactions work together with several hormones in the mutual cooperation. Therefore , As long as the secretion of a hormone which has been destroyed, or they were upset in the normal human body proportions, can lead to stunted growth . Conversely, if excessive secretion of hormones , can lead to uncontrolled growth . These growth-related hormone secreted by the pituitary gland , pancreas , gonads and thyroid . So how hgh affect human height growth? Affect the height growth is also testosterone ( a male hormone ) , secreted by the gonads of male or female , can promote bone growth and formation . Androgens in sexual maturity was most active, young people from 14 to 16 years old, You can see the most significant increase in height velocity In addition, the height growth also depends on the support of the pancreas secretes insulin , although it itself has no direct effect on the height, but only in the insulin hormone sufficient conditions can stimulate the growth. In the same genetic condition , why some people grow faster , some people grow slowly, while others are simply not grow ? Why some people in all aspects of growing conditions are good, but not growing taller ? In Fact, this is the body 's hormones to cause trouble.

The Effectiveness of Human Growth Hormone

The pituitary gland, also known as the master gland, is a vital part of the human body. One of the main functions performed by the master gland is the production of growth hormones.The deficiency of the growth hormone during childhood can result in a condition called as dwarfism while the excess production can result in a condition called as gigantism. The human growth hormone (HGH) is a natural hormone produced by our body. It regulates growth, metabolism and aids cell regeneration. I prefer to call it the wonder hormone simply because it provides a solution for many modern day health problems. The benefits of HGH include mood elevation, high energy, muscle building and strength, youthful skin, hair re-growth and healthy bones.
