Patients with active rheumatoid arthritis have higher intracellular levels of NLRP3 inflammasome components (including NLRP3, ASC, active caspase-1, and pro-IL-1β) as well as increased secretion of IL-1β [92] and monocytes from patients with rheumatoid arthritis show increased IL-1β production mediated by activation of NLRP3 inflammasome [93]. Here, IL1B is linked to rheumatoid arthritis.
