Cytokine secretion from piperacillin-stimulated CD4+ and CD8+ T-cell clones. Top left, mean ± SD levels of cytokine secretion from 14 CD4+ or CD8+ clones stimulated with piperacillin. Top right and bottom, comparison of IFN-γ, TNF-α, IL-4, IL-5, and IL-13 secretion by individual clones [values in the absence of antigen (less than 10 pg/ml, with the exception of IL-13 at 50 pg/ml) subtracted]. *, P < 0.05 when cytokine secretion with piperacillin-stimulated and unstimulated cells were compared.
