Mechanistic description

Circulating hs-CRP as Disease-Modifying Target via Microglial IL-1β Amplification

Mechanism / pathway

CRP → IL-1β → TLR4/MyD88 axis
→
immunomics

Evidence for (4)

Patients with elevated baseline hs-CRP (>3 μg/mL) showed 2.3× faster cognitive decline and increased CSF tau

PMID:29726919
IL-1β drives tau hyperphosphorylation via GSK-3β activation in mouse models

PMID:22306678
CRP binds to phosphocholine on apoptotic cells, activating NLRP3 inflammasome and IL-1β release

PMID:21616951
Microglial MyD88 deletion attenuates tau pathology in PS19 mice

PMID:31109924

Evidence against (4)

Mendelian randomization studies failed to demonstrate CRP genetic variants influence AD risk

PMID:24336809
Canakinumab (anti-IL-1β) trials showed no cognitive benefit despite CRP reduction - CANTOS trial was definitive negative

PMID:CANTOS
NSAIDs failed in AD prevention trials and may accelerate cognitive decline

PMID:18641406
IL1RN polymorphisms do not show consistent association with AD risk in genome-wide studies

PMID:GWAS
