Helicobacter based preparations comprising a pharmacologically active molecule of interest are disclosed, as well as methods of preparing and using said preparations. In particular, Helicobacter pylori vectors, vector plasmids and recombinant cells that include a sequence encoding a pharmacologically active molecule of interest useful in therapeutic treatments and/or vaccination against disease are provided. Delivery of the pharmacologically active molecules is provided at the mucosal surface, such as the gastric mucosa or nasal membranes, to provide effective and continuous delivery of a pharmacologically active agent. Vectors and shuttle vector constructs are also provided.

L'invention concerne des préparations à base d'Helicobacter contenant une molécule particulière présentant une activité pharmacologique, ainsi que de procédés de préparation et d'utilisation desdites préparations. L'invention porte plus particulièrement sur des vecteurs d'héliobacter pylori, des plasmides vecteurs, et des cellules recombinées, qui contiennent une séquence codant pour une molécule particulière présentant une activité pharmacologique, convenant pour des traitements thérapeutiques et/ou la vaccination contre une maladie. Ces molécules phamacologiquement actives sont administrées par une muqueuse telle que la muqueuse gastrique ou les membranes nasales, ce qui permet d'assurer la diffusion efficace et continue d'un agent pharmacologiquement actif. L'invention concerne également des vecteurs et des vecteurs navettes recombinés.
