MAP2 and systemic lupus erythematosus: Specifically in SLE, some autoantibodies such as anti-phospholipids(β2-glycoprotein 1 and cardiolipin), anti-ribosomal P protein, anti-NMDA,specifically subtype Glun2 or NR2, and anti-microtubule-associated protein 2 (MAP-2)are found but with variable frequency in neuropsychiatric SLE.15 Besides all these, anti-glutamatereceptor may be found to link these two diseases.14
