Title
(DE) NUKLEIKSÄURE-IMMUNIZIERUNG MITTELS EINES AUF EINEM VIRUS BASIERDEN INFEKTIONS/TRANSFEKTIONSSYSTEMS
(EN) NUCLEIC ACID IMMUNIZATION USING A VIRUS-BASED INFECTION/TRANSFECTION SYSTEM
(FR) IMMUNISATION A L'ACIDE NUCLEIQUE UTILISANT UN SYSTEME D'INFECTION/TRANSFECTION A BASE DE VIRUS
Abstract
(EN)
A method for nucleic acid immunization which results in a cell-mediated immunological response to a selected antigen is disclosed. The method utilizes the T7 RNA infection/transfection system which provides for the controlled, transient cytoplasmic expression of a given antigen and which elicits the production of class I MHC restricted CTLs.

(FR)
L'invention concerne un procédé d'immunisation à l'acide nucléique permettant d'obtenir une réaction immunologique à médiation cellulaire par rapport à un antigène sélectionné. Ce procédé utilise le système d'infection/transfection d'ARN de T7, qui assure l'expression cytoplasmique transitoire et contrôlée d'un antigène donné et qui provoque la production de lymphocytes T cytotoxiques (CTL) limités par CMH de classe I.
