Second, glatiramer acetate (GA), formerly known as copolymer 1, is widely used for treatment of MS via increasing the levels of Th2-related cytokines and CCR7 expression, decreasing Th1-related cytokines as well as the expression of CCR5, CXCR3, and CXCR6 on T cells [40, 76, 81–84]. The gene discussed is CCR5; the disease is myeloid sarcoma.
