WebJun 11, 2024 · Flagellin Induces Inflammasome Activation by Stimulated NAIP/NLRC4 and NLRP3 Receptors in HD-DC, but Not in HIV-DC Once assessed that FLG is able to induce inflammasome activation in MDDC, we therefore tried to depict the pathways involved in complex formation and to detect any differences between HD-DC and HIV-DC. 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.
