The Innate Immune Receptors TLR2/4 Mediate Repeated Social Defeat Stress-Induced Social Avoidance through Prefrontal Microglial Activation


Nie et al. identify TLR2/4 as crucial mediators of repeated stress-induced microglial activation in the mPFC, which leads to neuronal and behavioral changes through inflammation-related cytokines. These results highlight pivotal roles of innate immunity in the mPFC in repeated stress.
