Upon oral administration, fingolimod, as a structural analogue of sphingosine, selectively targets and binds to S1PR1 on lymphocytes and causes transient receptor activation followed by S1PR1 internalization and degradation. This results in the sequestration of lymphocytes in lymph nodes. By preventing egress of lymphocytes. fingolimod reduces both the amount of circulating peripheral lymphocytes and the infiltration of lymphocytes into target tissues. This prevents a lymphocyte-mediated immune response and may reduce inflammation. S1PR1, a G-protein coupled receptor, plays a key role in lymphocyte migration from lymphoid tissues. Fingolimod also shifts macrophages to an anti-inflammatory M2 phenotype, and modulates their proliferation, morphology, and cytokine release via inhibition of the transient receptor potential cation channel, subfamily M, member 7 (TRPM7)."}]
