Description_x000D_ Application_x000D_ FTY720 has been used as an immunomodulator and is used to investigate its effect on in vitro gastrulation model of P19C5 stem cells. It is also used to determine its efficacy in prolonging the survival corneal transplantation. FTY720 has been used to study its effect on the proliferation and differentiation of cultured embryonic hippocampal neural stem cells (NSCs) using the 5-bromo-2-deoxyuridine incorporation assay, the neurosphere formation assay and western blot analysis._x000D_ Packaging_x000D_ 5, 25 mg in glass bottle_x000D_ Biochem/physiol Actions_x000D_ FTY720 is an immunomodulating drug and sphingosine 1-phosphate (S1P) receptor modulator. Phosphorylation of FTY270 by sphingosine kinase causes S1P1R internalization, which sequesters lymphocytes in lymph nodes, preventing them from taking part in an autoimmune response. Clinically, it has been approved for the treatment of multiple sclerosis (MS). It has also been shown to block and reverse paclitaxel-induced chemotherapy induced peripheral neuropathy (CIPN) through S1PR inhibition as well as inhibit the activity of histone deacetylases in the hippocampus of mouse brains, thereby modulating memory.
