Abstract
Enriched large granular [human] lymphocytes treated with varying concentrations of prostaglandin E2 (PGE2) for varying time periods showed considerably reduced natural cytotoxicity against K-562 [human leukemia] target cells. The same cells when activated by lipopolysaccharide produced substantially less interleukin-1 (IL-1) as compared to cells not treated with PGE2. The inhibition of natural killer (NK) cell activity produced by PGE2 is due to inhibition of IL-1 production by these cells.
