Gut barrier dysfunction → peripheral inflammation**\nZonulin (pre-Haptoglobin 2) reversibly modulates intestinal tight junctions via PAR2 engagement. Elevated zonulin in dysbiosis permits LPS translocation across the gut epithelium, creating systemic endotoxemia. This is the initiating upstream event.\n\n**2. TLR4/MyD88/NF-κB signaling**\nLPS binding to TLR4 on resident gut macrophages and circulating monocytes activates MyD88-dependent signaling, driving IKK-mediated IκBα degradation and classical NF-κB activation. This transcriptional cascade upregulates NLRP3 priming signals (via NF-κB response elements) and generates pro-inflammatory cytokines including TNF-α, IL-6, and IL-1β. Critically, this creates the peripheral cytokine environment that"
