Detection and application of novel autoantibody anti-Septin9 antibody

The invention provides detection and application of a novel autoantibody anti-Septin9 antibody, and relates to the technical field of biological medicines. The invention provides an application of a reagent for detecting an anti-Septin9 autoantibody in preparation of a tool for diagnosing and/or treating nervous system autoimmune diseases, so that a new Septin9 autoantibody is found from serum of a patient suffering from nervous system diseases, and the Septin9 autoantibody is used as a targeted molecular marker related to the nervous system autoimmune diseases to diagnose and/or treat the nervous system autoimmune diseases. The anti-Septin9 antibody is a novel autoantibody for autoimmune diseases of the nervous system. By detecting the autoantibody, a basis is provided for diagnosis and treatment of nervous system autoimmune diseases, and the condition degree and the treatment effect of a patient can be monitored by detecting the titer change of the autoantibody. 本发明提供了一种新自身抗体抗Septin9抗体的检测及应用，涉及生物医药技术领域。本发明提
