Thymosin Alpha 1

Thymosin alpha 1 (Tα1) is a peptide hormone that is composed of 28 amino acids and has a molecular weight of 3,300 Da. The Tα1 molecule is composed of four α-helix regions that are stabilized by disulfide bonds between cysteine residues at positions 4 and 25, 7 and 19, 10 and 22, and 13 and 16.

Tα1 has been shown to play a role in the regulation of the immune system, specifically in the activation of T-cells. This peptide hormone has been shown to promote the differentiation and proliferation of T-cells, and to enhance the function of T-cells. Additionally, Tα1 has been shown to have anti-inflammatory effects, and to modulate the production of cytokines and other mediators of inflammation.
