The ATP-hydrolyzing ectoenzyme E-NTPD8 attenuates colonic inflammation through regulation of P2X4 receptor-dependent metabolism in myeloid cells [F0536]

Project description:Extracellular adenosine triphosphate (ATP) released by mucosal immune cells and by microbiota in the intestinal lumen elicits diverse immune responses that mediate the intestinal homeostasis via P2 purinergic receptors, while overactivation of the ATP signaling leads to disruption of mucosal immune system linked to pathogenesis of intestinal inflammation. In the small intestine, hydrolysis of luminal ATP by E-NTPD7 in epithelial cells is essential for control of the number of Th17 cells. However, the molecular mechanism underlying regulation of microbiota-derived ATP in the colon is poorly understood. Here, we show that E-NTPD8 is highly expressed in large intestinal epithelial cells and hydrolyzes microbiota-derived luminal ATP. Compared to wild-type mice, Entpd8-/- mice develop more severe DSS-induced colitis. In this context, either depletion of neutrophils and monocytes by injecting with anti-Gr-1 antibody or introduction of P2rx4 deficiency into hematopoietic cells ameliorates colitis in Entpd8-/- mice. Increased level of luminal ATP in the colon of Entpd8-/- mice promotes glycolysis in neutrophils and monocytes through P2X4 receptor-dependent Ca2+ influx, which links to prolonged survival and elevated ROS production in these cells. Together, these results indicate that E-NTPD8 limits intestinal inflammation by controlling metabolic alteration toward glycolysis via P2X4 receptor in myeloid cells.
