“… 53 Overproduction of IFN‐γ can contribute to autoimmune disease pathology, including NMOSD and multiple sclerosis. 54 , 55 , 56 Thus, GV‐971's inhibition of IFN‐γ may reduce the immune response in the NMOSD model. IL‐12p40, a subunit shared by interleukin‐12 (IL‐12) and interleukin‐23 (IL‐23), plays a significant role in inflammatory responses and autoimmunity.…”

AimsGrowing evidence suggests that an imbalanced gut microbiota composition plays a crucial role in the development of neuromyelitis optica spectrum disorders (NMOSD), an inflammatory demyelinating disease primarily affecting the optic nerves and central nervous system (CNS). In light of this, we explored the potential therapeutic benefits of GV‐971 in NMOSD. GV‐971 is a drug used for treating mild‐to‐moderate Alzheimer's disease, which targets the gut‐brain axis and reduces neuroinflammation.MethodsTo evaluate GV‐971's effects, we employed the experimental autoimmune encephalomyelitis (EAE) mouse model to establish NMOSD animal models. This was achieved by injecting NMO‐IgG into aged mice (11 months old) or using NMO‐IgG along with complement injection and microbubble‐enhanced low‐frequency ultrasound (MELFUS) techniques in young mice (7 weeks old). We assessed the impact of GV‐971 on incidence rate, clinical scores, body weight, and survival, with methylprednisolone serving as a positive control. In NMOSD models of young mice, we analyzed spinal cord samples through H&E staining, immunohistochemistry, and Luxol Fast Blue staining. Fecal samples collected at different time points underwent 16S rRNA gene sequencing, while plasma samples were analyzed using cytokine array and untargeted metabolomics analysis.ResultsOur findings indicated that GV‐971 significantly reduced the incidence of NMOSD, alleviated symptoms, and prolonged survival in NMOSD mouse models. The NMOSD model exhibited substantial neuroinflammation and injury, accompanied by imbalances in gut microbiota, peripheral inflammation, and metabolic disorders, suggesting a potentially vicious cycle that accelerates disease pathogenesis. Notably, GV‐971 effectively reduces neuroinflammation and injury, and restores gut microbiota composition, as well as ameliorates peripheral inflammation and metabolic disorders.ConclusionsGV‐971 attenuates the progression of NMOSD in murine models and reduces neuroinflammation and injury, likely through its effects on remodeling gut microbiota and peripheral inflammation and metabolic disorders.
