The Iron-Lock Loop: a proposed self-sustaining peritoneal circuit in endometriosis connecting Fusobacterium nucleatum, IL-6, hepcidin, iron accumulation, and reactive oxygen species — a cross-literature synthesis and coexistence hypothesis Authors/Creators Description This document presents a cross-literature synthesis identifying a self-sustaining mechanistic circuit in endometriosis that has not previously been described as an integrated loop in the published literature. Each component of the circuit is individually evidenced. The novel contribution is their integration into a named, unified sequence — the Iron-Lock Loop — in which Fusobacterium nucleatum translocates to the peritoneal cavity, induces sustained IL-6 secretion, triggers hepatic hepcidin elevation via the JAK/STAT3 pathway, suppresses ferroportin on peritoneal macrophages, causes iron accumulation and Fenton-reaction-driven reactive oxygen species generation, and thereby creates the precise oxidatively stressed, iron-rich sanctuary the bacterium requires to evade immune clearance and sustain dominance. The loop is self-perpetuating. The document further identifies that single-node interventions — iron chelation alone, hepcidin antagonism alone, or microbiome restoration alone — will produce limited durable benefit because the remaining nodes sustain the circuit. A formal research question is posed: whether a targeted multimodal protocol can shift the peritoneal immune microenvironment from its pathological attractor state to the known quiescent attractor state characteristic of asymptomatic endometriosis, and whether this shift correlates with symptom reduction and preserved endometrial receptivity. This is the coexistence hypothesis. A falsifiable prediction and proposed protocol targeting three simultaneous nodes — source reduction, loop interruption, and immune restoration — are provided. endometriosis, Fusobacterium nucleatum, hepcidin, iron metabolism, peritoneal microenvironment, IL-6, reactive oxygen species, coexistence hypothesis, peritoneal immunology, microbiome, cross-literature synthesis.
