Liver disease causes release of IBA1+ extracellular vesicles or cleavage products into circulation; these are taken up by microglia or mask epitopes, artifactually reducing detected IBA1 signal in situ. The skeptic identified this as a potential technical artifact, but the primary limitation is that serum IBA1 levels have not been correlated with brain IBA1 detection in cirrhosis patients. This hypothesis, if true, would fundamentally alter interpretation of all existing IHC studies.
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
