What determines the selective packaging of TREM2 into M2-type microglial exosomes versus other cargo?

OPEN

The study demonstrates that M2-like microglia produce TREM2-enriched exosomes, but the sorting mechanisms that preferentially package TREM2 into these vesicles remain unclear. This knowledge gap limits understanding of how to enhance therapeutic exosome production. Gap type: unexplained_observation Source paper: Microglial exosome TREM2 ameliorates ferroptosis and neuroinflammation in alzheimer's disease by activating the Wnt/β-catenin signaling. (2025, Scientific reports, PMID:40640358)
