Abstract
(EN) The present invention relates, e.g., to a Lactobacillus bacterium, which (1) expresses a recombinant polypeptide containing a lipoprotein signal sequence from the OspA protein of Borrelia burgdorferi, or an active variant of the leader sequence, operably linked to one or more heterologous polypeptide(s) of interest and/or (2) which comprises an expressible polynucleotide encoding a recombinant polypeptide, wherein the polynucleotide encodes a lipoprotein signal from the OspA protein of Borrelia burgdorferi, or an active variant thereof, which is operably linked to one or more heterologous polypeptide(s) of interest. In one embodiment, the heterologous polypeptide is from Yersinia pestis, the etiologic agent of plague. In another embodiment, the heterologous polypeptide is from Borrelia burgdorferi, the etiologic agent of Lyme disease. Also described are immunogenic compositions, such as live bacterial vaccines, comprising the bacterium; methods for eliciting an immune response against the polypeptide using the bacterium; and kits comprising the bacterium.
(FR) La présente invention concerne, par exemple, une bactérie Lactobacillus, qui (1) exprime un polypeptide recombiné contenant une séquence signal lipoprotéique d'une protéine OspA de Borrelia burgdorferi, ou un variant actif de la séquence de tête, liée fonctionnellement à un ou plusieurs polypeptides hétérologues présentant un intérêt, et/ou qui (2) comprend un polynucléotide pouvant être exprimé codant pour un polypeptide recombiné, le polynucléotide codant pour un signal lipoprotéique de la protéine OspA de Borrelia burgdorferi, ou un variant actif associé, liée fonctionnellement à un ou plusieurs polypeptides hétérologues présentant un intérêt. Dans un mode de réalisation, le polypeptide hétérologue est issu de Yersinia pestis, l'agent étiologique de la peste. Dans un autre mode de réalisation, le polypeptide hétérologue est issu de Borrelia burgdorferi, l'agent étiologique de la maladie de Lyme. L'invention concerne également des compositions immunogènes, telles que des vaccins bactériens vivants, comprenant la bactérie; des méthodes permettant de déclencher une réaction immunitaire contre le polypeptide, dans lesquelles est utilisée la bactérie; ainsi que des trousses comprenant la bactérie.
