This study revealed that genetic or pharmacological targeting of sphingosine 1–phosphate receptor-1 (S1P 1) facilitates a small-molecule-selective BBB opening, without major signs of CNS inflammation or injury. This size-selective BBB opening could be attributed to changes in the cytoskeletal association of tight junction proteins. WebJun 1, 2015 · S1P is a pleiotropic signaling molecule that regulates BBB permeability. • Fingolimod targets S1P receptors and may have therapeutic potential in BBB dysregulation. • S1P 1 primarily increases BBB integrity while S1P 2 enhances permeability. • Complex S1P pharmacokinetics modulate endothelial cell and astrocyte function.
