immune system
decreased macrophage cytokine production ( J:234239 )
• mice showed reduction in TNF secretion from macrophages in response to the Toll-like receptor 4 (TLR4) ligand, lipolysaccharide (LPS)
decreased interleukin-1 beta secretion ( J:234239 )
• some mice exhibited attenuated inflammatory responses related to decreased secretion of the proinflammatory cytokine interleukin (IL)-1 in response to priming with lipopolysaccharide (LPS) followed by nigericin treatment
decreased tumor necrosis factor secretion ( J:234239 )
• mice showed reduction in TNF secretion from macrophages in response to the Toll-like receptor 4 (TLR4) ligand, lipolysaccharide (LPS)

cellular
