| Research Abstract |
Extracellular ATP leads to immune responses in a wide spectrum of cell types (e.g., macrophages, T cells) and tissues. Our previous study shows that extracellular ATP-stimulated macrophages produce MIP-2. Thus, we investigated the role of ATP-mediated inflammatory response by macrophages in LPS-induced endotoxin shock model mouse. This study indicated that an increased production of reactive oxygen species by ATP-stimulated macrophages activates the signalling pathways that promote MIP-2 production which, in turn, induces neutrophil migration. Unfortunately, this pathway did not affect pathogenic mechanism in LPS-induced endotoxin shock model mouse.
