Dark Microglia Are Abundant in Normal Postnatal Development, where they Remodel Synapses via Phagocytosis and Trogocytosis, and Are Dependent on TREM2

This study identifies dark microglia in postnatal mouse hippocampus, showing they perform synapse remodeling via phagocytosis and trogocytosis and depend on TREM2.

Ketogenic diet alters microglial morphology and changes the hippocampal lipidomic profile distinctively in stress susceptible versus resistant male mice upon repeated social defeat

This study shows that a ketogenic diet promotes resistance to stress in mice by altering microglial morphology and lipid profiles in the hippocampus, with distinct effects in stress-susceptible and resistant mice.

Arg1+ microglia are critical for shaping cognition in female mice

This study identifies Arg1+ microglia as a distinct subtype in female mice, showing their role in cognitive function through dendritic spine maturation and behavior.

Stress-induced neuronal hypertrophy decreases the intrinsic excitability in stress habituation

The paper shows that repeated stress reduces intrinsic excitability of HPA axis neurons through increased cell size and membrane area, challenging conventional views on excitability plasticity.
