Discovery of the day
This multicenter retrospective study characterized the autoantibody profile in immune checkpoint inhibitor-induced optic neuritis (CBON), identifying aquaporin-4 (AQP4) and myelin oligodendrocyte glycoprotein (MOG) as the dominant autoantibodies. Among 88 patients with CBON drawn from a cohort of 2,321 ICI-treated individuals, seropositivity for AQP4 and MOG ranged from 17.3% to 32.4% across three independent cohorts, while these antibodies were virtually absent in matched controls. For a neurology researcher focused on neurodevelopmental disorders, these findings establish a serological framework for diagnosing a novel ICI-triggered neuro-inflammatory condition and highlight a potential model for studying aberrant autoantibody-mediated central nervous system injury relevant to developmental neuroimmunology.
