Abstract

La présente invention concerne un clone d'acide nucléique génétiquement modifié du virus de l'hépatite E (VHE) qui comprend les gènes structuraux (ORF2 et ORF3) et non structuraux (ORF1) complets, c'est à dire la séquence codante complète, du VHE, flanquée par les régions non codantes 5` et 3` avec une queue polyadénylée 3`dans la région non codante 3`, le clone précité étant capable d'infecter des cellules hépatiques en culture et de répliquer, transcrire et assembler le VHE qui s'y trouve. L'invention se rapporte également à un procédé permettant de synthétiser ce clone et à l'expression par ce dernier de protéines virales aptes à être utilisées pour détecter la présence d'anticorps dirigés contre le VHE dans des prélèvements biologiques. Le clone et les protéines virales exprimées de l'invention peuvent également être utilisés dans une trousse d'essai comprenant les protéines virales précitées, qui permet de diagnostiquer la présence d'une infection par VHE, dans un vaccin anti-VHE qui comprend des particules non infectieuses de VHE produites à partir d'une mutation du clone de l'acide nucléique du virus de l'hépatite E précité, et dans un système d'analyse qui permet de tester rapidement un médicament anti-VHE.
