Abstract
The invention relates generally to methods of influencing central nervous system cells to produce progeny useful in the treatment of CNS disorders. More specifically, the invention includes methods of exposing a patient suffering from such a disorder to a reagent that modulates the proliferation, migration, differentiation and survival of central nervous system cells via S1P or LPA signaling. These methods are useful for reducing at least one symptom of the disorder.
Claims9
A method of modulating the activity of an S1P, LPA, EDG receptor or a combination thereof, on an adult neural stem cell (NSC) comprising the step of exposing the cell expressing the receptor to a modulator agent selected from the group consisting of S1P, LPA or EDG receptor agonist, wherein the exposure induces increased NSC proliferation compared to untreated cells, and wherein the NSC is derived from adult brain, neural cell culture or a neurosphere.
A method for stimulating mammalian adult NSC proliferation comprising the step of contacting a cell population comprising mammalian adult NSC to an agent selected from the group consisting of an S1P, LPA or EDG receptor agonist to form a treated NSC, wherein the treated NSC cell shows increased proliferation compared to untreated cells, and wherein the NSC is derived from lateral ventricle wall of a mammalian brain.
A method for stimulating primary adult mammalian NSC to proliferate to form neurospheres comprising contacting the cell with an agent selected from the group consisting of an S1P, LPA or EDG receptor agonist to produce a proliferating NSC.
A method of enhancing neural stem cell proliferation in a patient having a central nervous system disorder comprising the step of infusing an S1P, LPA or EDG receptor agonist thereof into the patient, wherein neural stem cells show increased proliferation compared to untreated cells.
