Astrocytes exhibit robust circadian rhythms and release EVs containing regulatory RNAs and proteins. Astrocyte-derived EVs containing clock proteins (PER2, CRY1) or miRNAs can transfer circadian information to microglia. Enhancing astrocyte circadian output through SIRT1 activators (resveratrol) would indirectly entrain microglial circadian functions.

The miR-132/212 cluster is a well-established circadian modulator driven by CREB activity. Exosome-mediated delivery of miR-132 mimics engineered with microglial-binding peptides can target microglial BMAL1/CLOCK downstream effectors. miR-132 may suppress REV-ERBα, leading to disinhibition of Bmal1 transcription and enhancement of microglial circadian rhythmicity.
