Fig. 11

Schematic 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.
