NCIt definition : A synthetic analogue of thymosin-alpha-1, a 28-amino acid protein derived from the
precursor protein prothymosin-alpha. Exhibiting a variety of immunoregulating properties,
thymosin-alpha-1 induces differentiation of murine T-cell precursors and human thymocytes
and the terminal differentiation of functionally immature cord blood lymphocytes and
induces production of IL-2, high affinity IL-2 receptors, and B-cell growth factors
by peripheral blood mononuclear cells. T-helper and cytotoxic/suppressor T-cell populations
are targets of thymosin activity. Thymosin-alpha-1 has been shown to increase the
efficiency of antigen presentation by macrophages and to be an endogenous modulator
of alpha-thrombin activity. (NCI04);
