C1Q binding to macrophages via CD91/TLR2 heterodimers triggers NF-κB and STAT1 signaling, upregulating SR-A and CD36 scavenger receptors. This creates a feed-forward loop where C1Q-opsonized oxLDL internalization drives foam cell formation, which subsequently produces more C1Q. The mechanism connects the biomarker finding directly to disease progression and offers multiple druggable nodes (CD91, SR-A, CD36).
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
