Title: A New Mechanism of Action for Drugs Used to Treat Multiple Sclerosis for Cancer.

Abstract: Multiple Sclerosis (MS) is an autoimmune disease, whereas cancer develops in immunodeficient individuals. Natural killer (NK) cells stand at the cross road among treatment of autoimmune diseases and immunodeficient diseases. We reported a new mechanism of action for the drug Copaxone (glatiramer acetate or GA; TEVA Inc.). NK cells isolated from patients dosed with GA lysed dendritic cells isolated from the same patients as well killing tumor target cells. Similarly, vitamin D 3 or FTY720 (Gilenya; Novartis) augmented IL-2-activated NK cells lysis of tumor cells. Dimethyl fumarate (DMF;Biogen Inc.) is a new drug for treating MS patients. We have examined the effects of DMF and the metabolite monomethyl fumarate (MMF) on various activities of NK cells. Results: We demonstrate that MMF induces resting CD56 + NK cell lysis of the NK-sensitive K562 cells and the NK-resistant RAJI cells. More recently, we observed that GA, MMF and DMF up-regulate the expression of CCR10 on the surface of activated NK cells. This is corroborated with the ability of NK cells to migrate towards the concentration gradients of CCR10 ligands, namely CCL27 and CCL28. Conclusions: Our observations are the first to show that drugs used to treat multiple sclerosis can be used to direct the anti-tumor effector cells towards the sites of tumor growth, particularly those secreting the chemokine CCL27 such as melanomas or squamous cell carcinoma, or those secreting CCL28 such as colorectal carcinoma. Hence, drugs used to treat autoimmune diseases can be used to harness NK cells for the purpose of using them in cancer immunotherapy. Clinical protocols using this novel strategy will be discussed.,
