Compositions and methods for enhancing the immune response of a mammal to an antigen by engaging the OX-40 receptor on the surface of T-cells are disclosed, comprising administering to the mammal a composition comprising a purified OX-40 receptor binding agent and a pharmaceutically acceptable carrier, wherein said composition is administered to the mammal such that the OX-40 receptor binding agent is presented to T-cells of the mammal during or shortly after priming of the T-cells by the antigen. Such compositions and methods can be used in immunization and cancer treatment.
La présente invention concerne des compositions et des techniques favorisant chez un mammifère une réponse immunitaire à un antigène par engagement du récepteur OX-40 sur la surface de lymphocytes T. La technique consiste à administrer à un mammifère une composition comprenant un agent de liaison purifié du récepteur OX-40 et un porteur pharmaceutiquement acceptable, l'administration se faisant de telle sorte que l'agent de liaison du récepteur OX-40 soit présenté à des lymphocytes T du mammifère pendant ou peu de temps après l'amorçage desdits lymphocytes. Ces compositions et techniques peuvent s'employer à des fins d'immunisation et pour le traitement du cancer.
