Discovery of the day
This multicenter retrospective study of 88 patients with immune checkpoint inhibitor-induced optic neuritis (CBON) identifies aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) as the dominant autoantibodies driving the condition, with seropositivity rates ranging from 17.3% to 32.4%. Longitudinal serum analysis from 12 patients revealed a clear seroconversion pattern where these antibodies were undetectable pre-ICI treatment but emerged at symptom onset, persisting in a subset of follow-up samples, while remaining virtually absent (0–2%) in matched control patients. For your work in preclinical models of chronic pain and neuroscience at the Brain and Mind Centre, this finding provides a novel serological framework that could inform diagnostic classification and future mechanistic studies of neuroinflammatory conditions relevant to understanding immune-mediated neurological dysfunction.
