Abstract:
:Prothymosin alpha, a polypeptide of 109 to 111 amino acid residues, contains the entire thymosin alpha 1 sequence (residues 1-28) at its amino terminal. Human peripheral blood monocytes incubated with prothymosin alpha release thymosin alpha 1 in the culture supernatants. In addition total RNA is found to increase. The production of thymosin alpha 1 involves de novo protein synthesis as shown by the kinetics of this release and its inhibition by actinomycin D and cycloheximide. Thymosin alpha 1 release, possibly in association with HLA-DR, stimulates the proliferation of the T cell population.
