Recombinant C1-esterase inhibitor (Ruconest) blocks C1R/C1S proteolytic activity, preventing classical pathway activation without affecting lectin or alternative pathways. This reduces opsonization of apoptotic cells, C5b-9 formation, and downstream inflammatory cytokine production, promoting a more stable plaque phenotype. The hypothesis leverages an already-approved biologic with established safety data.
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
