The crucial role of NRP3 inflammasomes in the development of rheumatoid arthritis was investigated by Vande Walle et al. showing that knock out of A20, a rheumatoid arthritis susceptibility gene, in mice led to increased expression of NLRP3 and pro-IL-1β genes and resulted in induction of NLRP3 inflammasome-mediated caspase-1 activation, pyroptosis, and IL-1β secretion [91]. The gene discussed is CASP1; the disease is rheumatoid arthritis.
