As the first CARD filament structure in … WebIntroduction. The inflammasome is an intracellular multimeric complex molecule of approximately 700 kDa that can be activated by cellular infection or stress signals, and it can modify and mature a variety of inflammatory factor precursors, such as pro-IL-1β and pro-IL-18, thereby participating in the human innate immune response and a variety of diseases.

WebNLRP3 inflammasome detects danger signals such as crystalline uric acid and extracellular ATP released by damaged cells. These signals release HSP90 and SGT1 from and recruit ASC protein and caspase-1 to the inflammasome complex. Caspase-1 within the activated NLRP3 inflammasome complex in turn activates the inflammatory cytokine, IL-1β. [14] WebResults. rFlaA:Betv1 consistently activated all types of investigated macrophages, inducing higher IL-1β secretion compared with the equimolar mixture of both proteins. rFlaA:Betv1-induced activation of THP-1 macrophages was shown to be independent of either the TLR5-activating sequence motif or the flagellin DC0 domain but depended on both NLRP3- and … WebMay 11, 2024 · Inflammasomes are molecular platforms for caspase-1 activation and are typically composed of three parts: a sensor protein, adapter protein, and pro-caspase-1 [15] (Figure 1).
