WebJan 1, 2009 · Although flagellin may augment NLRC4-mediated caspase-1 activation, the direct ligand for NLRC4, as for most of the NLR family members, remains to be determined. Identification of the ligand for NLRC4 will help resolve many of the above questions and will enhance our understanding of the specificity built into the innate immune system. WebMar 21, 2024 · 4.2 rFlaA:Betv1 induces dual NLRP3- and NLRC4-inflammasome activation. Flagellin can be recognized by both TLR5 on the cell surface and NLRC4 in the cytosol (1, 33). Several studies have revealed a sequence stretch of eight highly conserved amino acids in flagellins N-terminal D1 domain (QRVRELAV) to be important for binding …

WebDetails NLRC4 BACKGROUND: The NLRC4 (aka Ipaf) inflammasome is an intracellular multi-protein complex that plays a central role in innate immunity [1,2]. It is activated by a two-step process; a first signal (‘priming’) is provided by microbial molecules such as TLR ligands, while the second signal is provided by intracellular bacterial molecules such as … WebIn this review we give an overview of the NAIP/NLRC4 activation mechanism as well as the described roles of this inflammasome, with a focus on in vivo infection and pathology. After ligand recognition by NAIP sensor proteins the NAIP/NLRC4 inflammasome forms through oligomerization with the NLRC4 adaptor to activate Caspase-1.
