title: [Milrinone suppresses TNF-alpha and IL-1 beta release in mouse peritoneal macrophages].
abstract: Tumor necrosis factor-alpha (TNF-alpha) exerts a wide spectrum of biological activities and contributes to the pathophysiology of septic shock. We studied whether milrinone suppresses TNF-alpha and IL-1 beta releases from mouse peritoneal macrophages. Mouse peritoneal macrophages were stimulated for 18 hr with lipopolysaccharide and different doses of milrinone. TNF-alpha release was suppressed in a dose-dependent fashion with milrinone, reaching half-maximal inhibition at 30 microM. Release of IL-1 beta was not suppressed with 25 microM of milrinone, but it was suppressed with 250 microM of milrinone. We conclude that TNF-alpha release is suppressed by therapeutically administered milrinone.
