title: [Cellular regulation of human lymphocyte mitogenic factor release in vitro].
abstract: Production of the mitogenic facotr by human lymphocytes stimulated with phytohemagglutinin (PHA) was investigated. Anti-PHA antibodies were used for studying the culture medium mitogenic activity. The mitogenic factor production markedly increased after lymphocyte irradiation. When macrophages were eliminated, using iron powder, mitogenic factor generation was also increased. It was demonstrated that lymphocyte irradiation and macrophage elimination stimulated the mitogenic factor production throgh different mechanisms.
