Fig. 11From: CXCR5 down-regulation alleviates cognitive dysfunction in a mouse model of sepsis-associated encephalopathy: potential role of microglial autophagy and the p38MAPK/NF-κB/STAT3 signaling pathwaySchematic diagram depicting the possible mechanisms through which CXCR5 regulates autophagy. MAPK signaling downstream of CXCR5 induced by LPS promotes the up-regulation of NF-κB/STAT3 axis. Consequently, activation of NF-κB/STAT3 pathway contributes to incomplete activation of autophagy and production of inflammatory cytokines, thereby impairs learning and memory function. CXCR5 down-regulation results in inhibition of MAPK/NF-κB/STAT3 axis and activation of autophagy in brain, which leads to the improved cognitive function in mice with sepsis-associated encephalopathy.
