Title
(EN) CONSTITUTIVE EXPRESSION OF NON-INFECTIOUS HIV-LIKE PARTICLES
(FR) EXPRESSION CONSTITUTIVE DE PARTICULES NON INFECTIEUSES DU TYPE HIV
Abstract
(EN) Non-infectious, non-replicating immunogenic HIV-like particles are produced by stable long-term constitutive expression in mammalian cells by eliminating elements toxic to the mammalian cells. An expression vector contains a nucleic acid molecule comprising a modified HIV genome devoid of long terminal repeats and wherein $i(Tat) and $i(vpr) sequences are functionally disabled and a constitutive promoter operatively connected to the modified HIV genome for constitutive expression of the modified genome to produce the HIV-like particles.
(FR) La présente invention concerne des particules non infectieuses, non répliquantes, immunogènes du type VIH, produites par une expression constitutive stable sur une période prolongée dans des cellules mammifères, en éliminant les éléments toxiques pour les cellules précitées. Un vecteur d'expression comprend une molécule d'acide nucléique renfermant un génome VIH modifié exempt de répétitions terminales, dans lequel les séquences $i(Tat) et $i(vpr) sont fonctionnellement bloquées, et un promoteur constitutif relié de manière fonctionnelle au génome VIH modifié pour l'expression constitutive du génome modifiée, de manière à produire les particules du type HIV.
