Sevoflurane/NF-κB induces systemic IL-6, driving hepatic C3 production via STAT3. Circulating C3 enters the brain through sevoflurane-disrupted BBB, where microglial NF-κB-mediated mechanisms cleave C3 to active C3b for synaptic opsonization and complement-dependent elimination.
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
