Molecular mechanism of pyroptosis in the form of lytic programmed cell death is characterized by its highly inflammatory nature and is most frequently observed following intracellular pathogen infections. TLR: Toll-like receptor, TRIF: TIR-domain-containing adapter-inducing interferon-β, MYD88: myeloid differentiation primary response protein 88, TAk1: transforming growth factor (TGF)-β-activated kinase 1, TAB: TAK1-binding protein, IKK: nuclear factor kappa-B kinase, NF-κB: nuclear factor kappa B, NLRP3: nod-like receptor family pyrin domain containing 3, AIM2: absent in melanoma-2, NLRC4: nod-like receptor family CARD domain containing 4, and NALP1: nucleotide-binding oligomerization domain-like receptor family, pyrin domain-containing 1. Purple ellipse indicted a complex.
