Overview of the alveolar NLRP3 inflammasome activation on alveolar innate cells during M. tuberculosis infection. The host PRRs (TLR4) is activated by M. tuberculosis surface PAMPs stimulate the NF-kB transcriptional factor to transcribe IL1, IL18, and CASP4/11 that are processed by activation of the inflammasome complex through NLRP3 and CASP1.
