Abstract

Humoral factors of the thymus participate in the processes which lead to maturation and acquisition of immunocompetence of cells of the lymphoid system (1,2). We have demonstrated that THF, a thymic factor partially purified in our laboratory (3,4), induces immune maturation of thymus derived lymphoid cells via an obligatory rise in cellular levels of cAMP and in membranal adenyl cyclase activity (5,6). We have now isolated and partially characterized the chemical properties of THF with the aim to further understand the processes which lead to differentiation of thymus derived cells.
