Patent

CA 2186913

Methods of introducing genetic material into cells of an individual and compositions and kits for practicing the same are disclosed. The methods comprise the steps of contacting cells of an individual with a genetic vaccine facilitator and administering to the cells a nucleic acid molecule that is free of retroviral particles. The nucleic acid molecule comprises a nucleotide sequence that encodes a protein that comprises at least one epitope that is identical or substantially similar to an epitope of a pathogen antigen or an antigen associated with a hyperproliferative or autoimmune disease, a protein otherwise missing from the individual due to a missing, non-functional or partially functioning gene, or a protein that produces a therapeutic effect on an individual. Methods of prophylactically and therapeutically immunizing an individual against HIV are disclosed. Pharmaceutical compositions and kits for practicing methods of the present invention are disclosed.

La présente invention concerne des procédés d'introduction de matériel génétique dans les cellules d'un individu ainsi que les compositions et les trousses permettant de réaliser cette opération. Ces procédés consistent à mettre en contact les cellules d'un individu avec un agent favorisant la vaccination génétique et à administrer aux cellules une molécule d'acide nucléique exempte de particules rétrovirales. La molécule d'acide nucléique comprend soit une séquence de nucléotides codant une protéine comportant au moins un épitope identique ou essentiellement semblable à un épitope d'un antigène pathogène ou un antigène associé à une maladie hyperproliférante ou auto-immune, soit une protéine autrement absente chez un individu en raison de l'absence, du non-fonctionnement ou du fonctionnement partiel d'un gène, soit encore une protéine produisant un effet thérapeutique sur un individu. L'invention concerne ensuite des procédés d'immunisation prophylactique et thérapeutique d'un individu contre le virus VIH. L'invention concerne enfin des compositions et des trousses permettant de réaliser cette opération.
