Sevoflurane elevates IL-1β in the hippocampus (pmid:32716529). Consistent with this, IL-1β upregulates C3 in brain cells via NF-κB signaling (pmid:10899056), supporting astrocyte-microglia crosstalk mediated by IL-1β in neuroinflammation (pmid:30102911). However, the current evidence indicates that the IL-1β–C3 link does not extend directly to C1q, as C1q and C3 are regulated by distinct pathways (pmid:10899056), and IL-1β receptor expression in microglia is variable (pmid:30102911), indicating
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
