title: [Comparative assessment of the efficacy in humoral response of T-cells of various organ origin and their substitutes].
abstract: A linear dependence of the response to the thymus-dependent antigen (log of the plaque-forming cell count) on the T cell dose at the initial curve section was observed in syngeneic transfer of T and B cells mixture. The exponential slope differed for T cells of different origin and could serve as the measure of helper activity. In case of an excess of T-lymphocytes the response reaches the maximum, whose level is independent of the organic origin of T cells. By the helper activity T cells are distributed in the following order: T cells of the spleen and cortisone-resistant thymocytes greater than T cells of the lymph nodes greater than cortisone-sensitive thymocytes. There was established a quantitative equivalence by the capacity to activate B cells between the T-lymphocytes and E. coli lipopolysaccharide.
