When speaking about thymosin alpha 1, we know that it’s a 28 amino acid peptide which naturally occurs in the thymus gland and has been known to modify and regulate the immune system via its action as a toll-like receptor and TLR-2 agonist.
Naturally present thymosin 1 in the body intensifies t-cell maturation and differentiation, the activity of natural killer cells, and also cytokine-mediated inflammation.
