The activation of the NLRP3 inflammasome is involved in several pathological processes and conditions, including obesity, diabetes mellitus, gout, rheumatoid arthritis, tumors, subarachnoid hemorrhage, neurodegenerative disorders, Crohn's disease, chronic obstructive pulmonary disease, asthma, cryopyrin-associated periodic syndrome, geographic atrophy, and sepsis [121]. Here, NLRP3 is linked to subarachnoid hemorrhage.
