The TNF-α/NF-κB axis has been implicated in sevoflurane-associated neuroinflammation (pmid:34512547). TNF-α may potentiate complement synthesis within the CNS (pmid:15282354), and inflammatory cytokines including TNF-α can induce C1r/C1s expression (pmid:25620734). However, the specific mechanistic link from TNF-α to neuronal and astrocyte C1r/C1s expression in the sevoflurane neurotoxicity context has not been demonstrated (pmid:15282354). Furthermore, while C1r/C1s could theoretically combine
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
