Selective targeting of TREM2 anti-inflammatory (NFκB-antagonistic) domain without phagocytic activation. The neuroprotection in TYROBP deficiency may result from uncoupling two TREM2 functions: phagocytosis (requires full-length TREM2 and SYK via TYROBP) versus anti-inflammatory NFκB antagonism (mediated by TREM2 C-terminal fragment independently).

**Background and Rationale** Triggering Receptor Expressed on Myeloid cells 2 (TREM2) represents one of the most significant genetic risk factors for late-onset Alzheimer's disease, with rare loss-of-function variants conferring up to threefold increased risk of dementia. This single-pass transmembrane receptor, exclusively expressed on microglia within the brain, has emerged as a critical regulator of microglial phenotype and function throughout the lifespan. Under physiological conditions, TR

TREM2 shedding does not affect inhibition of NFκB activation but completely blocks phagocytosis PMID:31649511
TREM2 mutations drastically impact phagocytosis and NFκB antagonism differently PMID:31649511
Differential downstream signaling in microglia lacking Alzheimer's-related TREM2 or its adaptor TYROBP/DAP12 PMID:41659250

Soluble TREM2 (sTREM2) has agonistic activity in some contexts, potentially competing with membrane-bound TREM2 for liga PMID:39817909
