MIR-150 is upregulated or downregulated in many autoimmune diseases, such as multiple sclerosis (MS) (100), myasthenia gravis (MG) (101–103), systemic lupus erythematosus (SLE) (104–106), rheumatoid arthritis (RA) (107–109), and primary Sjogren’s syndrome (pSS) (110). This evidence concerns the gene MIR150 and myasthenia gravis.
