Induction of a protective immune response in a mammal by injecting a DNA sequence
First Claim
Patent Images
1. A process for inducing a protective immune response in a mammal, comprising:
- injecting into muscle or skin of said mammal a construct comprising a noninfectious, nonintegrating DNA sequence encoding an immunogen linked to a promoter sequence which can control the expression of said DNA sequence in said mammal, in an amount sufficient that uptake of said construct occurs, and sufficient expression results, to induce said protective immune response,wherein said construct is free from association with transfection-facilitating viral particles, liposomal formulations or charged lipids.

Abstract
A method for delivering an isolated polynucleotide such as DNA or RNA, to the interior of a cell in a mammal comprising the injection of an isolated polynucleotide into a muscle of the mammal where the polynucleotide is taken up by the cells of the muscle and exerts a therapeutic effect on the mammal. The method can be used to deliver a therapeutic polypeptide to the cells of the mammal, to provide an immune response upon in vivo translation of the polynucleotide, to deliver antisense polynucleotides, to deliver receptors to the cells of the mammal or to provide transitory gene therapy.

2. A process for providing a mammal with an immunogen, and thereby generating desired antibodies in said mammal due to the action of the immune system of said mammal on said immunogen, comprising:
-
injecting into muscle or skin of said mammal a construct comprising a noninfectious, nonintegrating DNA sequence encoding said immunogen linked to a promoter sequence which can control the expression of said DNA sequence in said mammal in an amount sufficient that uptake of said construct occurs, and sufficient expression results, to generate said desired antibodies, wherein said construct is free from association with transfection-facilitating viral particles, liposomal formulations or charged lipids. - View Dependent Claims (10)
