title: [Assessment of the action of taktivin on different stages of T-lymphocyte maturation].
abstract: Tactivin, the thymic hormone preparation, evokes some phenotype alterations in T-cell precursors (elimination of SC-1 antigen and expression of Thy-1-antigen) and cortical thymocytes (a decrease in the number of thymocytes carrying PNA-receptor) similar to those arising in T-cell differentiation. Tactivin induces PNA+ -thymocyte response to PHA action and increases PHA response to PNA- -thymocytes. It is weakly mitogenic for T-cell precursors and PNA- -thymocytes. The data suggest that Tactivin may be used for the treatment of immune deficiencies with T-cell differentiation and function defects.
