Mechanistic description

NLRP3 inflammasome activation releases IL-1β, driving complement cascade upregulation and synapse elimination. MCC950 or CNS-optimized NLRP3 inhibitors block this pathway. Requires validation of BBB penetration in symptomatic aged models.

Mechanism / pathway

  1. NLRP3
  2. neurodegeneration

Evidence for (4)

  • NLRP3 KO mice protected from cognitive deficits in 3xTg AD model

    PMID:26675736

  • IL-1β infusion causes spine loss in healthy mice

    PMID:24489802

  • MCC950 crosses BBB and reduces neuroinflammation

    PMID:30638571

  • Active caspase-1 observed in AD human brains
