title: Mitogen-induced suppressor T cell activity in the in vitro cellular immune response.
abstract: A 24 h preincubation of human peripheral lymphocytes (PBL) in the presence of phytohemagglutinin (PHA) or concanavalin A (Con. A) renders them suppressive for the response of untreated cells to PHA, Con. A, candidin and allogeneic cells. However, cells stimulated with lipopolysaccharide (LPS) show no suppression.
