From Analysis:

What is the temporal sequence of TREM2 signaling transition from protective to inflammatory during aging?

While TREM2 was identified as critical for microglial senescence, the debate lacked fine-grained temporal data on when and how TREM2 signaling shifts from neuroprotective to pathogenic. Understanding this transition timing is essential for intervention strategies.

Description

The TREM2 R47H AD risk variant causes a locked immunometabolic switch that prevents microglial metabolic adaptation to chronic phagocytic challenges. R47H microglia accumulate cholesteryl esters, leading to ER stress and NLRP3 inflammasome activation, accelerating the protective-to-inflammatory transition.

Dimension Scores

How to read this chart: Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential. The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength), green shows moderate-weight factors (safety, competition), and yellow shows supporting dimensions (data availability, reproducibility). Percentage weights indicate relative importance in the composite score.
