For example, a variety of autoantibodies have been detected in the CSF of SLE patients, including anti-glutamate receptor ɛ2 subunit (GluRɛ2)[3], anti-neuronal[4], anti-ganglioside[5], anti-glial fibrillary acidic protein[6], anti-dsDNA, anti-N-methyl-d-aspartate (NMDA) receptors[7], anti-triose-phosphateisomerase[8], anti-SSA/Ro (Anti-Sjögren’s-syndrome-related antigen A, or anti-Ro)[9], anti-ribosomal P protein[10], anti-cardiolipin[11], and anti-alpha-internexin autoantibodies[12]. Here, GRIA2 is linked to systemic lupus erythematosus.
