Comparing 2 hypotheses side-by-side
This hypothesis proposes that TREM2-dependent microglial senescence is mechanistically driven by dysregulated acid sphingomyelinase (ASM) activity and ceramide accumulation in aging microglia. During normal aging, TREM2 signaling undergoes fundamental changes that disrupt sphingolipid homeostasis, leading to increased ASM activity in microglial lysosomes. This creates a pathological ceramide-rich environment that triggers the senescence-associated secretory phenotype (SASP) and transforms protec
**Overview** This hypothesis proposes selective pharmacological modulation of acid sphingomyelinase (ASM, encoded by SMPD1) to restore ceramide homeostasis and ameliorate Alzheimer's disease pathology. ASM catalyzes the hydrolysis of sphingomyelin to ceramide in acidic compartments (lysosomes, late endosomes). In AD, ASM activity is dysregulated, leading to ceramide accumulation, lysosomal dysfunction, autophagy impairment, and neuroinflammation—processes that drive both Aβ and tau pathology. S
