Fingolimod [(FTY720), Gilenya; 2-amino-2-[2-(4-octylphenyl)ethyl]-1,3-propanediol], a new drug for the treatment of relapsing multiple sclerosis, acts through its phosphate metabolite, which modulates sphingosine 1-phosphate receptors. This represents a novel mechanism of action. In the present work, the absorption and disposition of (14)C-labeled fingolimod were investigated in healthy male vo...

Fingolimod (FTY720), a novel class of sphingosine 1-phosphate receptor modulators, has received special interest among ophthalmologists, particularly given that oral administration of FTY720 has proven to effectively treat corneal graft rejection in animal models. However, no studies have examined the performance of FTY720 as an ophthalmic solution in reducing corneal rejection in high-risk cor...

Insufficient proliferation, differentiation, and migration are the main pitfalls of neural stem cells (NSCs) in reparative therapeutics for the central nervous system (CNS) diseases. The potent lipid mediator sphingosine-1-phosphate (S1P) regulates cells' biological behavior broadly in the CNS. However, the effects of activating S1P on NSCs are not quite clear. In the current study, FTY720 (Fin...

Sphingosine 1-phosphate (S1P), a lysophospholipid mediator, is generated from sphingosine by sphingosine kinases and binds five known cell surface receptors. S1P receptor 1 (S1P1) plays an essential role in lymphocyte egress from secondary lymphoid organs (SLO), as evinced by the inability of lymphocytes to exit from the SLO in mice lacking lymphocytic S1P1. Fingolimod hydrochloride (FTY720) is...

FTY720 (Fingolimod) is known to have a significant therapeutic effect on experimental autoimmune encephalomyelitis (EAE). Here, we used an EAE mouse model, which had been established by immunizing C57BL/6J mice with a partial peptide of myelin oligodendrocyte glycoprotein (MOG₃₅₋₅₅), to examine the relapse of EAE upon discontinuation of treatment with FTY720 alone or in combination with MOG₃₅₋₅...

Fingolimod (FTY720) is a new generation oral treatment for multiple sclerosis (MS). So far, FTY720 was mainly considered to target trafficking of immune cells but not brain cells such as neurons. Herein, we analyzed FTY720's potential to directly alter neuronal function. In CNS neurons, we identified a FTY720 governed gene expression response. FTY720 upregulated immediate early genes (IEGs) enc...

FTY720 (Fingolimod) is a first-in-class sphingosine 1-phosphate (S1P) receptor modulator that inhibits S1P-dependent lymphocyte egress from secondary lymphoid organs. Oral administration of FTY720 shows a superior efficacy compared to interferon (IFN)-β in relapsing remitting multiple sclerosis (MS), the most common inflammatory disorder of the central nervous system (CNS) and in experimental a...

Sphingosine 1-phosphate (S1P), a lysophospholipid mediator, is generated from sphingosine by sphingosine kinases and binds 5 types of G protein-coupled S1P receptors. It has been well documented that S1P receptor type 1 (S1P1) plays an essential role in lymphocyte egress from secondary lymphoid organs (SLO), because lymphocytes are unable to exit from SLO to periphery in mice lacking lymphocyti...

Therapeutic administration of fingolimod hydrochloride (FTY720), the functional antagonist at sphingosine 1-phosphate (S1P) receptor 1 (S1P1) shows a marked improving effect on experimental autoimmune encephalomyelitis (EAE) induced by myelin oligodendrocyte glycoprotein (MOG) in C57BL/6 mice. However, this treatment showed an only partial inhibition of Th1/Th17 cell infiltration into the centr...

Fingolimod (FTY720) is a first-in-class orally bioavailable compound that has shown efficacy in advanced clinical trials for the treatment of multiple sclerosis (MS). In vivo, fingolimod is phosphorylated to form fingolimod-phosphate, which resembles naturally occurring sphingosine 1-phosphate (S1P), an extracellular lipid mediator whose major effects are mediated by cognate G protein-coupled r...
