Abstract
Gain-of-function mutation in NLRP3 is associated with a spectrum of autoinflammatory disorders including familial cold autoinflammatory syndrome, Muckle-Wells syndrome, and neonatal onset multisystem inflammatory disease, collectively known as cryopyrin-associated periodic syndrome (CAPS). However, the cell types mediating the pathogenesis of CAPS are not completely understood. Two studies in EMBO Reports now demonstrate that gain-of-function Nlrp3 mutation in either macrophages or neutrophils alone is sufficient to trigger systemic autoinflammation and lethality in mice.
