Recent studies have focused attention on the involvement of NLRP1 to confer susceptibility for extended autoimmune/inflammatory disorders, being considered a common risk factor in autoimmunity.1–3 NLRP1 provides a scaffold for the assembly of the inflammasome that activates caspases 1 and 5, required for processing and activation of the proinflammatory cytokines interleukin 1β (IL-1β), IL-18 and IL-33 and promoting inflammation.4 In this study, we examined for the first time whether NLRP1 is associated with giant cell arteritis (GCA), a chronic systemic vasculitis affecting large and medium-sized arteries derived from the aorta, in particular the cranial branches of the carotid artery. GCA is the most common vasculitis in the elderly in Western countries with a female predominance.5 To investigate the possible genetic association of NLRP1 with this disease, we genotyped a single-nucleotide polymorphism (rs8182352), which has been reported to confer risk to the development of autoimmune processes in previous studies,1 ,2 in a total of 3583 individuals, comprising a discovery set from Spain (574 patients diagnosed with biopsy-proven GCA and 2366 healthy controls) and a replication set of subjects from Italy (111 biopsy-proven GCA patients and 532 controls) using a predesigned TaqMan allele discrimination assay. All individuals were of …
