MOG-IgG binds myelin oligodendrocyte glycoprotein on oligodendrocytes, engaging activating Fcγ receptors (FcγRI, FcγRIII) on perivascular/spinal cord macrophages, triggering antibody-dependent cellular phagocytosis and release of pro-inflammatory cytokines. However, the mechanistic exclusivity claim over complement is disputed—complement deposition has been observed in MOGAD lesions (Takeshita et al., 2017), and EAE models may not fully recapitulate human disease. The pathway requires integratio
In the established paradigm, microglia are primary drivers of neuroinflammation. However, oligodendrocyte-derived IL-6 may prime microglia through IL-6 trans-signaling (IL-6/sIL-6R/gp130), creating a self-reinforcing inflammatory loop. Blocking soluble IL-6 receptor (sIL-6R) specifically at the oligodendrocyte-microglia interface would interrupt this amplification circuit without globally suppressing IL-6, preserving its neuroprotective functions. This extends the SASP-complement cascade concept
