    The NLRP3 inflammasome is a key component of the innate immune system, primarily found in immune cells.

  • 2

    NLRP3 activation leads to the release of pro-inflammatory cytokines IL-1β and IL-18, which mediate immune responses.

  • 3

    Crystalline silica and asbestos fibers activate the NLRP3 inflammasome, contributing to lung diseases such as silicosis and asbestosis.

  • 4

    The activation of NLRP3 involves a priming step and subsequent activation triggered by various stimuli, including DAMPs and PAMPs.

  • 5

    Pyroptosis, mediated by caspase-1, results in cell lysis and further inflammation through the release of additional cytokines.
