The mRNA expression for different inflammasomes and its components such as, NLRP3, NLRC4, NAIP, AIM2, ASC, CASPASE-4, and CASPASE-1 genes were performed by quantitative Real time PCR in UPEC infected UTI patients (N = 40) and in controls healthy group (N = 40). Here, NLRP3 is linked to bacterial urinary tract infection.
