What is TB-500 peptide (Thymosin Beta-4)?

is a synthetic analogue of the naturally occurring Thymosin Beta-4 peptide which ubiquitously exists in human and animal cells. The biologically effective peptide belongs to a ubiquitous family of 16 related molecules with a high degree of sequence conservation and localization in the majority of the tissues and circulating cells in the body. TB-500 sequesters and blocks actin polymerization in eukaryotic cells.

TB-500 expression increased four-six fold during early angiogenesis. It promotes the growth of new blood cells from the existing vessels. TB-500 mediates faster wound healing when injected subcutaneously and also promotes healing of muscle injury and development. TB-500 further catalyzes cellular migration through its interaction with actin cytoskeleton. The actin-binding domain happens to be a short central stretch of amino acid and is involved in TB-500 mediated regulation of blood cell division; wound healing, migration of endothelial cells and keratinocytes as well as higher production of extracellular matrix-degrading enzymes.

The peptide is one of the most effective wound healing molecules with anti-inflammatory properties. Thymosin Beta-4 unlike other growth factors helps in endothelial and keratinocyte migration. It also does not bind to the extracellular matrix and has a very low molecular weight which helps it to travel comparatively long distances through tissues. As mentioned before, it regulates the polymerization and function of actin.

Effects of Thymosin Beta-4 Peptide Demonstrated In Recent Studies

TB-500 peptide has been observed to mediate following functions in recent studies such as:
– Tissue repair
– Endothelial (blood vessels) cell differentiation
– Angiogenesis in dermal tissues
– Collagen deposition
– Keratinocyte movement
Reduction in inflammation of tissue in joints
– Increase in muscle growth causing improvement in endurance and strength
– Relaxation of muscle spasm and improvement of muscle tone
– Increase in the intracellular exchange of substances
– TB-500 control of connective tissue flexibility
– Prevention of the formation of adhesions and fibrous bands in muscles, tendons and ligaments.
