Comparing 2 hypotheses side-by-side
Cross-reactive CD8+ T cells recognize viral (EBV, HSV, HHV-6) or cancer antigens presented on MHC class I by spinal neurons, leading to perforin/granzyme B release and RIPK3-dependent necroptosis. However, motor neuron RIPK3 susceptibility is unproven (Kay et al., 2016), anti-Hu mechanisms involve dendritic cell antigen presentation rather than direct killing, and some paraneoplastic myelopathies improve with IVIG/rituximab, suggesting reversible antibody-mediated components. The exclusivity cla
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
