Anti-Tac monoclonal antibody identifies the receptor for interleukin 2 (IL 2, or T cell growth factor) present on activated human T lymphocytes. By using tritiated anti-Tac, a sensitive and specific binding assay to evaluate cell surface IL 2 receptor expression is reported. IL 2 receptors on human peripheral blood lymphocytes can be detected within 6 h after PHA . Similar effects were produced by incubation with phospholipase C but not interleukin 1. Because both PMA and phospholipase C result in activation of protein kinase C, these data suggest the possibility that activation of protein kinase C may induce IL 2 receptor expression.
