Does the cancer-cystatin-C-TREM2 pathway protect against tau pathology and other AD hallmarks beyond amyloid?

PARTIALLY ADDRESSED

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)
