TREM2 splice isoforms generate soluble TREM2 species that disrupt long-term potentiation

TREM2 is a transmembrane receptor expressed by myeloid cells and acts to regulate their immune response. TREM2 governs the response of microglia to amyloid and tau pathologies in the Alzheimer’s disease (AD) brain. TREM2 is also present in a soluble form (sTREM2), and its CSF levels fuctuate as a function of AD progression.
