Description

The abstract focuses exclusively on amyloid plaque reduction, leaving unknown whether this pathway addresses tau tangles, neuroinflammation, or synaptic loss. Since AD is multifactorial, understanding the full therapeutic scope is essential for clinical translation.

Gap type: open_question Source paper: Peripheral cancer attenuates amyloid pathology in Alzheimer’s disease via cystatin-c activation of TREM2. (2026, Cell, PMID:41576952)

Resolution criteria

[“Cross-sectional analysis of AD brains (n>=50) shows inverse correlation between cancer-cystatin-C-TREM2 pathway activation and Braak stage for tau tangles (AT8 IHC)”, “Genetic activation of cystatin-C pathway in P301S tauopathy mice reduces hippocampal tau tangle burden by >=40%”, “TREM2 knockout mice crossed with cancer-prone AD models show no change in amyloid but accelerated tau pathology”, “Single-nucleus RNA-seq confirms cystatin-C reduces microglial complement activation markers in tau models”]
