Abstract

Antibodies persist months and years in blood. Chronic presence of low titers of blood circulating anti-NMDAR1 autoantibodies are sufficient to impair cognitive function in the integrity of the BBB in mice, suggesting potential cognitive damaging effects of low titers of blood circulating anti-NMDAR1 autoantibodies in the general human population and psychiatric patients. Investigation of anti-NMDAR1 autoantibodies against individual NMDAR1 antigenic epitopes may potentially provide risk biomarkers and therapeutic targets for development of immunotherapy as a precision medicine for psychiatric patients in the future.

血液循环中抗 NMDAR1 自身抗体对认知的影响
抗体在血液中会持续数月甚至数年。血液循环中低滴度的抗 NMDAR1 自身抗体的长期存在足以损害小鼠认知功能和 BBB 的完整性,这表明血液循环中低滴度的抗 NMDAR1 自身抗体可能对普通人群和精神病患者的认知能力造成损害。针对单个 NMDAR1 抗原表位的抗 NMDAR1 自身抗体的研究有可能提供风险生物标志物和治疗靶点,以便在未来将免疫疗法发展为精神病患者的精准医疗。
