IFNG (interferon-γ) is a type-2 interferon, which is produced by Th (T helper cells)-1 lymphocytes, CD8 cytotoxic lymphocytes, natural killer (NK) cells, and natural killer T (NKT) cells. It plays an important role in innate and adaptive immune responses, and helps in defense against bacterial infections, dimorphic yeast and some viral infections. High expression of IFNG is common in many autoimmune diseases, such as systemic lupus erythematosis, Sj?gren syndrome, inflammatory bowel disease and multiple sclerosis.
