Similarly, the significant sequence homology between Coxsackie virus P2-C protein and glutamate decarboxylase in humans may trigger type 1 diabetes [11], while ankylosing spondylitis, systemic lupus erythematosus (SLE), and Lyme disease may be induced by antigens such as pulD from Klebsiella sp., OSP-A from Borrelia sp., and nuclear antigen-1 from Epstein–Barr virus [12,13]. Here, GLUL is linked to systemic lupus erythematosus.
