Comparing 2 hypotheses side-by-side
Chronic hyperactivation of classical complement in the atherosclerotic intima leads to C1S-mediated opsonization of late apoptotic foam cells, but paradoxically blocks efficient clearance. C5b-9 membrane attack complex deposition on surviving cells causes secondary necrosis, releasing cholesterol crystals and DAMPs that amplify local inflammation and expand the necrotic core. The hypothesis requires C1Q to 'flip' from its known homeostatic role to pathological at high lesional concentrations.
C1Q binding to modified LDL particles triggers Syk kinase signaling and mitochondrial ROS production, providing a priming signal for NLRP3 inflammasome assembly in lesional macrophages. This mechanism creates a feed-forward inflammatory loop where C1Q-opsonized cholesterol crystals activate caspase-1, driving IL-1β/IL-18 secretion and perpetuating plaque inflammation. The hypothesis leverages the CANTOS trial precedent for IL-1β-targeted therapy in atherosclerosis, offering a clear translational
