Patent

CA 2402211

Disclosed are phosphatidylserine (PS) receptors, including PS receptors from human, mouse, Drosophila melanogaster and Caenorhabditis elegans. Also disclosed are homologues of such receptors, nucleic acids encoding such receptors and homologues thereof, as well as agonist and antagonist compounds that specifically associate with and affect the activation state of such receptors. Preferred agonists and antagonists of PS receptors according to the invention include antibodies, antibody fragments and binding partners that selectively bind to such a receptor. Also disclosed are methods of making and using the PS receptors, homologues thereof, and agonist and antagonist compounds of such receptors. In particular, methods for reducing inflammation, for treating an autoimmune disease, for enhancing transplantation of tissue grafts, methods of increasing anti-tumor immunity, and methods for inhibiting viral and parasitic infections are described.

L'invention concerne des récepteurs de phosphatidylserine (récepteurs PS), y compris des récepteurs humains, murins, Drosophila melanogaster et Caenorhabditis elegans. L'invention concerne également des homologues de tels récepteurs, des acides nucléiques codant pour de tels récepteurs et les homologues de ceux-ci, ainsi que des composés agonistes et antagonistes s'associant spécifiquement à l'état d'activation de tels récepteurs, et affectant cet état d'activation. Les agonistes et les antagonistes des récepteurs PS recommandés et décrits dans la présente invention comprennent des anticorps, des fragments d'anticorps et des partenaires de liaison se liant de manière sélective à un tel récepteur. L'invention concerne également des procédés permettant de créer et d'utiliser les récepteurs PS, leurs homologues, et les composés agonistes et antagonistes de tels récepteurs. En particulier, l'invention concerne des procédés permettant de réduire l'inflammation, de traiter une maladie auto-immune, d'améliorer la transplantation de greffes tissulaires; des procédés permettant d'augmenter l'immunité contre les tumeurs; et des procédés permettant d'inhiber des infections virales et parasitaires.
