Microglia-dependent regulation of fear memory extinction
Paul W. Frankland
Nature Neuroscience, Published online: 04 May 2026; doi:10.1038/s41593-026-02286-0 Liu et al. show in mice that microglia are recruited to the soma and dendritic processes of fear engram neurons during extinction learning and that they weaken fear memories by temporarily silencing and remodeling the engram neurons.
