We observe the impact of AFAP1-AS1 silencing in M2 macrophages on essential effector and regulatory proteins like MMP9, CCL5 and CXCL10 in MS patients receiving different treatments (Fingolimod, Interferon beta-1a, Interferon beta-1b, Teriflunomide or Dimethyl fumarate). The gene discussed is CCL5; the disease is myeloid sarcoma.
