Hu Gang's team revealed that microglia promote toxic astrocytes formation and induce depression-like behavior
Time of Update: 2023-01-06
1038/s41586-022-05328-2The images in the article are from referencesFigure 1: Increased activation of hippocampal neurotoxic astrocytes after stress2NLRP3 regulates the increase of astrocytes in the hippocampusGiven that NLRP3 regulates phenotypic transitions in A1 astrocytes and increases hippocampal NLRP3 levels after CMS, they constructed NLRP3 total knockout mice and found that knocking out NLRP3 was able to attenuate CMS-induced depression-like behavioral disorders, reduce the number of hippocampal A1 astrocytes, and attenuate synaptic protein loss.
