RESPOSTAS IMUNITARIAS CONTRA ANTIGENIOS DOS VPH, SUSCITADAS POR COMPOSICOES QUE INCORPORAM UM ANTIGENIO DE VPH E UMA PROTEINA DO STRESS OU UM VECTOR DE EXPRESSAO COM APTIDAO PARA A EXPRESSAO DESTAS PROTEINAS

This document describes compositions and methods for inducing an immune response (e.g., a cellular response such as a cell-mediated cytolytic immune response) to a human papillomavirus (HPV) antigen, which can be displayed by HPV or exhibited by infected cells (e.g., cells from cervical and other tumors). The HPV protein can be joined to a stress protein by chemical conjugation or noncovalently using linking moieties, or by fusion (e.g., a recombinant fusion protein). Also described are expression vectors containing sequences encoding HPV antigens and stress proteins, which can be introduced into cells of a subject or cells ex vivo. Also described are compositions that include a stress protein linked to an HPV antigen and another pharmacologically acceptable component and stress protein -HPV antigen fusions and conjugates. These compositions can be used to induce or enhance an immune response against HPV and cells that exhibit HPV antigens, including HPV-associated tumors.
