However, Lasithiotaki et al. revealed distinct NLRP3 inflammasome activation profiles between RA-UIP and IPF [120], with significantly higher levels of IL-1β and IL-18 in bronchoalveolar lavage fluid (BALF) from RA-UIP patients compared with IPF patients. Here, NLRP3 is linked to idiopathic pulmonary fibrosis.
