While motor neurons release mtDNA cell-autonomously, astrocytes phagocytose dying neurons and encounter released mtDNA, activating astrocyte cGAS/STING to induce chronic inflammatory phenotype (CXCL10, IL-6, complement). This creates neurotoxic rather than neuroprotective inflammation. Cell-type-specific STING inhibition in astrocytes represents an attractive therapeutic approach but requires validation of the phagosomal mtDNA-to-cytosol mechanism.
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
