Abstract: Disclosed is an application of sBCMA as a biomarker in cerebrospinal fluid in diagnosis and monitoring of antibody-mediated central nervous system autoimmune diseases. Taking NMOSD as an example, the level of sBCMA in cerebrospinal fluid of NMOSD patients is significantly higher than that of control subjects matched for age and gender, and there is a positive correlation between the level of sBCMA in cerebrospinal fluid and a nerve injury-related index NFL, a blood-cerebrospinal fluid barrier breakdown-related index QAlb, or a neuroinflammation-related index sTREM2 in cerebrospinal fluid of NMOSD patients. This indicates that the level of sBCMA in cerebrospinal fluid can be used as a biomarker for the diagnosis of antibody-mediated central nervous system autoimmune diseases such as NMOSD and the evaluation of the severity of nerve injuries, the degree of damage to blood-cerebrospinal fluid barrier, and the level of neuroinflammation in patients.
