title: Modulation of interleukin-15-induced suppression of human neutrophil apoptosis by TNFalpha.
abstract: Human interleukin-15 (IL-15) is a proinflammatory cytokine to suppress neutrophil apoptosis, which is a potential therapeutic agent. The modulatory effect of TNFalpha was investigated in IL-15-induced suppression of human neutrophil apoptosis. TNFalpha was shown to reverse the ability of IL-15 to delay neutrophil apoptosis within certain time course. Moreover, this reverse effect by TNFalpha might be associated with a reduction of the expression of the anti-apoptotic Bcl-Xl protein detected by Western blotting. It is concluded that TNFalpha can be used to modulate IL-15-induced suppression of neutrophil apoptosis within certain time course.
