Flagellin nlrc4 activation
WebMay 3, 2024 · IRF8 governs the transcription of Naips to allow detection of flagellin or T3SS proteins to mediate NLRC4 inflammasome activation. Furthermore, we found that IRF8 confers protection against bacterial infection in vivo, owing to its role in inflammasome-dependent cytokine production and pyroptosis. WebA flagellin-conjugate protein induces dual NLRC4- and NLRP3-inflammasome activation which modulates inflammatory cytokine secretion from macrophages Yen-Ju Lin, Annette Jamin, Sonja Wolfheimer, Anna Fiedler, Ann-Christine Junker, Alexandra Goretzki, Stephan Scheurer, and Stefan Schülke*
