These findings support previous research that identified PtpA as an immunogenic agent for MAP-related diseases, such as arthritis, multiple sclerosis, Hashimoto’s thyroiditis, Crohn’s disease, systemic lupus erythematosus, and type 1 diabetes mellitus [4, 7, 8, 11, 27, 35]. The gene discussed is PTPA; the disease is multiple sclerosis.
