CA 2570114

The invention provides a DNA plasmid comprising: (a) a first transcriptional unit comprising a nucleotide sequence that encodes a first polypeptide operably linked to regulatory elements including a first promoter and a first polyadenylation signal; (b) a second transcriptional unit comprising a nucleotide sequence that encodes a second polypeptide operably linked to regulatory elements including a second promoter and a second polyadenylation signal; (c) a third transcriptional unit comprising a nucleotide sequence that encodes a third polypeptide operably linked to regulatory elements including a third promoter and a third polyadenylation signal; and wherein said first, said second and said third promoters are each derived from different transcriptional units; and wherein said first, said second and said third polyadenylation signals are each derived from different transcriptional units. The invention further relates to immunogenic compositions for inducing an immune response to HIV comprising combinations of two, three, or four plasmids, where each plasmid is expressing a defined antigen, which may be a single antigen or a fusion of two or three antigens.

L'invention concerne un plasmide d'ADN comprenant: (a) une première unité de transcription renfermant une séquence nucléotidique codant un premier polypeptide lié de manière fonctionnelle à des éléments de régulation comprenant un premier promoteur et un premier signal de polyadenylation; (b) une deuxième unité de transcription comprenant une séquence nucléotidique codant un deuxième polypeptide lié de manière fonctionnelle à des éléments de régulation comprenant un deuxième promoteur et un second signal de polyadenylation; (c) une troisième unité de transcription comprenant une séquence nucléotidique codant un troisième polypeptide lié de manière fonctionnelle à des éléments de régulation comprenant un troisième promoteur et un troisième signal de polyadenylation; les premier, deuxième et troisième promoteurs étant dérivés individuellement de diverses unités de transcription; les premier, deuxième et troisième signaux de polyadenylation étant dérivés individuellement de différentes unités de transcription. L'invention concerne également des compositions immunogènes permettant d'induire une réponse immune au VIH et comprenant des combinaisons de deux, trois ou quatre plasmides, chaque plasmide exprimant un antigène défini, pouvant être un antigène unique ou une fusion de deux ou trois antigènes.
