Cytokine Production in Cell Culture by Peripheral Blood Mononuclear Cells from Immunocompetent Hosts

The production of interleukin 2 (IL-2) gamma interferon, IL-4, tumor necrosis factor alpha (TNF-α), TNF-β, IL-5, and IL-10 in vitro by peripheral blood mononuclear cells cultured from healthy immunocompetent subjects after mitogen stimulation was determined. The mitogens used were concanavalin A, phytohemagglutinin, pokeweed mitogen, and Staphylococcus aureus Cowen. The results obtained provide a normal range for the production of these cytokines under specified conditions in vitro.
