NLRP1 and mesothelioma: In conclusion, our study, performed on patients and controls with homogeneous asbestos exposure, does not confirm the involvement of NLRP1 inflammasome in the susceptibility to mesothelioma in Italian patients, pointing out the necessity to analyze a wider number of individuals, such as those used in the most recent genome wide studies, to deeper investigate the contribution of the inflammasome to the multifactorial mesothelioma.
