Extracellular ATP leads to immune responses in a wide spectrum of cell types (e.g., macrophages, T cells) and tissues. However, it remains unclear whether such ATP-activated macrophages modulate the magnitude of immune responses to actual tissue injury. Thus, we investigated the role of ATP-mediated inflammatory response by macrophages in LPS-induced endotoxin shock. This study indicated that the binding of extracellular ATP to P2purinergic receptors on macrophages increases neutrophil infiltration via the production of MIP-2. However, in this pathway, further examination was required because P2purinergic receptor of the having many kinds was related.

细胞外ATP在多种细胞类型（如巨噬细胞、T细胞）和组织中引起免疫反应。然而，目前尚不清楚这种atp激活的巨噬细胞是否调节实际组织损伤的免疫反应的大小。因此，我们研究了atp介导的巨噬细胞炎症反应在lps诱导的内毒素休克中的作用。本研究表明，细胞外ATP与巨噬细胞p2嘌呤能受体的结合通过产生MIP-2增加中性粒细胞浸润。然而，在这一途径中，由于与多种p2嘌呤能受体相关，需要进一步的研究。
