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