How Does Gilenya Work?
It is still unclear how exactly Gilenya works to treat MS. The drug is classified as a "sphingosine 1-phosphate receptor modulator." It binds to certain receptors in the body and prevents lymphocytes from leaving the lymph nodes. This decreases the number of lymphocytes in the bloodstream. A lymphocyte is a type of white blood cell that plays an important role in the immune system.
