Comparing 2 hypotheses side-by-side
**Mechanistic Foundation** Specialized pro-resolving mediators (SPMs) - including resolvins, protectins, and maresins - are endogenous lipid mediators that actively terminate neuroinflammation and promote tissue repair. Unlike anti-inflammatory drugs that merely block inflammatory pathways, SPMs actively stimulate resolution programs: clearance of apoptotic debris, restoration of blood-brain barrier integrity, and regeneration of damaged neural tissue. In Alzheimer's disease, SPM biosynthesis i
**Background and Rationale** TREM2 variants represent major genetic risk factors for Alzheimer's disease, with loss-of-function mutations increasing dementia risk threefold. While TREM2 is exclusively expressed on microglia, emerging evidence suggests its primary pathogenic role occurs through disrupted astrocyte-microglia communication rather than intrinsic microglial dysfunction. Healthy brain homeostasis depends on coordinated responses between these glial populations, where TREM2+ microglia
