Sevoflurane anesthesia activates NF-κB (RELA/p65) via ROS-mediated IKK activation, a pathway implicated in neuroinflammation. NF-κB consensus binding sequences have been identified in human and mouse C1QA promoter regions, and TNF-α-induced C1q expression in astrocytes has been shown to be NF-κB-dependent, suggesting a potential mechanism for complement C1q synthesis in microglia. This could provide a cell-autonomous mechanism linking anesthesia-induced neuroinflammation to complement-mediated s
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
