[Effect of thymosin on human lymphocyte subpopulations in vitro]. / Vliianie timozina na subpopuliatsii limfotsitov cheloveka in vitro.

The incubation of healthy donors peripheral blood lymphocytes with thymosin was shown to increase the content of high avide "active" lymphocytes bearing receptors for SRBC, lymphocytes bearing receptors for C(2) component of complement and for Fc-portion of immunoglobulins. The proportion of cap-forming Ig-positive lymphocytes was shown to increase too. The role of T and B lymphocyte subpopulations and their precursors as thymosin action target cells is discussed.
