摘要: Phorbol myristate acetate (pma) is a potent mitogen for human peripheral blood lymphocytes (PBL) comparable to phytohemagglutinin (PHA) in potency. Inactivation of PHA-responsive by 5'-bromodeoxyuridine and light treatment left the PMA response intact nice versa. Experiments separating rosetting with sheep erythrocytes (SRBC) demonstrated that PMA-responsive segregate those have high affinity SRBC greater than PHA- or concanavalin A (Con A)-responsive cells. These results indicate population resides within T-lymphocyte appears be distinct from responding PHA Con A. may useful clinically assay size function "active" rosette population.
