Due to the restriction of apoptosis and other regulatory mechanisms, neutrophils have a short survival time in vivo. Because of the death domain of cytoplasmic regions, some members of tumor necrosis factor receptor superfamily (TNFRSF) are defined as death receptors, such as TNFR-I, Fas and DR4/DR5. TNF-α, FasL and TRAIL, which are known as apoptosis-inducing ligand, can bind to death receptors and activate intracellular apoptosis pathways to induce apoptosis. Accumulating studies found that these three apoptosis-inducing ligands play an important role in the immune system by coordinating with neutrophil, which including neutrophil recruitment/infiltration and function performing. In this review, we summarize existing studies targeting neutrophils as diagnosis and treatment for diseases, and focus on the involvement of neutrophils which regulated by apoptosis-inducing ligands in inflammatory diseases under current cognition.Keywords: neutrophil, apoptosis-inducing ligand, infectious inflammation, sterile inflammation
