Abstract

La présente invention a trait à un micro-organisme recombinant comportant une mutation modulant l'expression d'un gène impliqué dans la biosynthèse, la modification ou la dégradation d'un constituant de paroi cellulaire ou exprimant un gène étranger perturbant la biosynthèse, la modification ou la dégradation d'un constituant de paroi cellulaire et comportant un vecteur d'expression conduisant à la production d'un polypeptide présentant une activité prophylactique ou thérapeutique. L'invention a également trait à un procédé permettant la délivrance de polypeptides à des muqueuses, comprenant l'administration à une muqueuse d'un sujet (humain ou animal) d'une composition comportant un micro-organisme recombinant comportant une mutation modulant l'expression d'un gène impliqué dans la biosynthèse, la modification ou la dégradation d'un constituant de paroi cellulaire ou exprimant un gène étranger perturbant la biosynthèse, la modification ou la dégradation d'un constituant de paroi cellulaire et dans lequel le polypeptide à délivrer est produit par ledit micro-organisme recombinant.
