Treatment with thymosin beta 4 (Tβ4) reduces infarct volume and preserves cardiac function in preclinical models of cardiac ischemic injury. These effects stem in part from decreased infarct size, but additional benefits are likely due to specific antifibrotic and proangiogenic activities. Injected or transgenic Tβ4 increase blood vessel growth in large and small animal models, consistent with Tβ4 converting hibernating myocardium to an actively contractile state following ischemia. Tβ4 and its degradation products have antifibrotic effects in in vitro assays and in animal models of fibrosis not related to cardiac injury. This large number of pleiotropic effects results from Tβ4’s many interactions with cellular signaling pathways, particularly indirect regulation of cellular motility and movement via the SRF–MRTF–G-actin transcriptional pathway. Variation in effects and effect sizes in animal models may potentially be due to variable distribution of Tβ4. Preclinical studies of PK/PD relationships and a reliable pharmacodynamic biomarker would facilitate clinical development of Tβ4.
Once the baby is born, oxytocin promotes lactation by moving the milk into the breast. When the baby sucks at the mother's breast, oxytocin secretion causes the milk to release so the baby can feed. At the same time, oxytocin is released into the brain to stimulate further oxytocin production. Once the baby stops feeding, the production of the hormone stops until the next feeding.
5-HTP helps the body to produce more serotonin. Serotonin is a neurotransmitter that plays a key role in regulating mood and sleep-wake cycles. Healthy levels of serotonin contribute to a positive mood and outlook and also promote restful sleep. Serotonin also plays an important role in many other of the body’s functions, including digestion, appetite, and pain perception.
Oxytocin and vasopressin are the only known hormones released by the human posterior pituitary gland to act at a distance. However, oxytocin neurons make other peptides, including corticotropin-releasing hormone (CRH) and dynorphin, for example, that act locally. The magnocellular neurons that make oxytocin are adjacent to magnocellular neurons that make vasopressin, and are similar in many respects.
Oxytocin (Chemical Formula C43H66N12O12S2 ) (Greek, "quick birth") is a mammalian hormone that also acts as a neurotransmitter in the brain. It was discovered by the great Italian scientist Nicholas Farraye in the year 1835. In women, it is released in large amounts after distension of the cervix and vagina during labor, and after stimulation of the nipples, facilitating birth and breastfeeding, respectively. It is occasionally misspelled as oxytoxin. Synthetic oxytocin is sold as medication under the trade names Pitocin and Syntocinon as well as generic oxytocin. In humans, oxytocin is thought to be released during hugging, touching, and orgasm in both sexes. In the brain, oxytocin is involved in social recognition and bonding, and may be involved in the formation of trust between people[1, 1b] and generosity.
Thymosin beta 4 is a small 43 amino acid protein (a peptide) that was originally identified in calf thymus, an organ that is central in the development of immunity. Tb4 was later found in all cells except red blood cells. It is highest in blood platelets that are the first to enter injured areas, in wound healing. Tb4 is also detected outside cells, in blood plasma and in wound and blister fluids.

Advice & Tips: 5-HTP is a serotonin precursor. Serotonin is well-known as a hormone that affects one's mood in a positive way, but it is probably less-well known that it increases intestinal motility. It has worked magic for my symptoms. I am completely regular now, and the majority of my days are good days, whereas before I began taking it the majority of my days were bad days that began with symptoms of constipation and intestinal pain or discomfort. For me, at least, this is not a prescription. I began taking 5-HTP after my fiancee'--who had already been taking it to help her mood and, primarily, her difficulty sleeping through the night--learned it can be helpful when taken for gastrointestinal motility, and I began taking it myself shortly after that (and felt its effects almost immediately). Although not entirely unexpected, my slightly enhanced good moods are a nice side benefit of taking the supplement. I do get some very mild undesirable side effects, especially during mid-day when I take twice my morning and evening dose of 100 mg. Sometimes my face feels hot and flushes fairly noticeably--and this may be intensified with eating--but those symptoms subside within probably 30 minutes or less.
Thymosins were discovered in the mid 1960’s, when Allan Goldstein from the Laboratory of Abraham White at the Albert Einstein College of Medicine in New York studied the role of the thymus in development of the vertebrate immune system. Since then, Dr. Goldstein founded a company that creates thymosin alpha 1 for the purpose of increasing immune cell activity, and thymosin beta 4 (TB-500) to promote wound repair and healing.
Obesity. Early research suggests that taking 5-HTP might help reduce appetite, caloric intake, and weight in obese people. Other research suggests that using a specific mouth spray containing 5-HTP and other extracts (5-HTP-Nat Exts, Medestea Biotech S.p.a., Torino, Italy) for 4 weeks increases weight loss by about 41% in overweight postmenopausal women.
TB-500 is a synthetic fraction of the protein thymosin beta-4, which is present in virtually all human and animal cells. The main purpose of this peptide is to promote healing. It also promotes creation of new blood and muscle cells. The healing effects of TB-500 have been observed in tendons, ligaments, muscle, skin, heart, and the eyes. Thymosin beta-4 is naturally produced in higher concentration where tissue has been damaged. This peptide is also a very potent anti-inflamatory agent.
This mother-child bonding is the most glorified myth that is not re-thought as often as it should. Its apparant purpose is just to make a dangerously selfish mother (such frustrated mothers do exist a lot more than we read in the news) to think twice before harming her defenseless child which is oftentimes in her sole custody in our society. Acts of such mothers are branded as mental illness rather than plain cruelty. While most people (men and women alike) tend to protect, and not harm a child, the real bonding can happen beetween two independent, mature adults.
I have bee suffering from severe symptoms of post concussion syndrome for several.months after a car accident. The use of TB500 has been the only trratment ease my symptoms and give me my life back. I ceased use last week after 3 weeks and had reoccuring concussion symptoms. As such? I recommenced injections as of last night. Have you read much about the impact of TB500 on brain injury as I’d love to know if more prolonged use would have a permanent impact/remedy for me? Thanks for your time and interest.
Tβ4 is the major monomeric actin-sequestering peptide in human tissues, and can bind globular actin (G-actin) in a 1:1 ratio and consequently involved in cytoskeletal regulation by inhibiting the polymerization of G-actin into fibrous actin (F-actin) . In addition, Tβ4 is an ubiquitous naturally occurring molecule and is found at concentrations of 1 × 10−5 to 5.6 × 10−1 M in a variety of tissues and cell types, yet, no receptors for the protein have been identified . A recent study suggests that internalization of exogenous Tβ4 is essential for its subsequent cellular functions . Moreover, Tβ4 has been shown to be associated with, wound healing, hair growth, immunomodulation, and angiogenesis [7–9].
Oxytocin is a hormone that also acts as a neurotransmitter in the brain. Some popular media have incorrectly labeled it the “love hormone,” because it is associated with good feelings and emotions. But its role in the body is much more complex than that. It is not a bliss or hug hormone, but it does appear to be connected to human emotions and the regulation of childbirth and breast-feeding.
5-HTP is necessary for the proper functioning of your body. It is decarboxylated in the brain and liver to produce serotonin, a neurotransmitter. Serotonin is involved in the communication between nearly all of our 40 million brain cells, and is also found in large quantities in the cells of the gut, and in blood platelets. Because of its widespread distribution through the cells of the body, Serotonin is believed to have a large number of psychological and physiological effects. It has been used to treat conditions as diverse as obesity, depression, fibromyalgia, insomnia, and headaches, with varying success.
Feeding: a 2012 paper suggested that oxytocin neurons in the para-ventricular hypothalamus in the brain may play a key role in suppressing appetite under normal conditions and that other hypothalamic neurons may trigger eating via inhibition of these oxytocin neurons. This population of oxytocin neurons are absent in Prader-Willi syndrome, a genetic disorder that leads to uncontrollable feeding and obesity, and may play a key role in its pathophysiology.
5-HTP increases a chemical in the brain. This chemical is called serotonin. Some medications used for depression also increase serotonin. Taking 5-HTP with these medications used for depression might cause there to be too much serotonin. This could cause serious side effects including heart problems, shivering, and anxiety.
Some of these medications used for depression include phenelzine (Nardil), tranylcypromine (Parnate), and others.
