[NLRP3](/proteins/nlrp3) (NLR Family Pyrin Domain Containing 3) is a pattern recognition receptor that forms the [NLRP3 inflammasome](/entities/nlrp3-inflammasome), a multi-protein complex that activates caspase-1 and triggers the release of pro-inflammatory cytokines IL-1β and IL-18. The NLRP3 inflammasome is a central driver of neuroinflammation in Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders.
NLRP3 contains three functional domains:
In the healthy nervous system, NLRP3:
NLRP3 contributes to AD pathogenesis through:
In PD, NLRP3 mediates:
NLRP3 inflammasome activation follows a two-step priming and activation model:
NLRP3 inflammasome inhibitors are actively being developed:
| Strategy | Compound | Status | Notes |
|----------|----------|--------|-------|
| NLRP3 inhibitors | MCC950 | Preclinical/Phase I | Direct NLRP3 ATPase inhibition |
| | Dapansutrile (OLT1177) | Phase II | β-sulfonyl nitrile compound |
| | Tranilast | Approved (allergy) | Repurposed for NLRP3 |
| IL-1β targeting | Anakinra, Canakinumab | Approved | IL-1 receptor antagonist |
| ASC inhibition | Small molecules | Research | Block inflammasome assembly |
| Caspase-1 inhibitors | VX-765 | Clinical trials | Prevent cytokine activation |
