Microglia regulate nucleus accumbens synaptic development and circuit function underlying threat avoidance behaviors

This study shows that microglia are essential for excitatory synapse formation in the nucleus accumbens during early development, impacting threat avoidance behaviors in adulthood.

Serotonin sensing by microglia conditions the proper development of neuronal circuits and of social and adaptive skills

This study shows that serotonin signaling through microglial 5-HT2B receptors during early development is critical for normal neuronal circuit maturation and social behavior.

Microglia drive pockets of neuroinflammation in middle age

The paper shows that microglia in specific brain regions exhibit premature aging-related inflammation in middle age, which may affect nearby neurons.
