Vibrio cholerae lipopolysaccharide loaded chitosan nanoparticle could save life by induction of specific immunoglobulin isotype

Abstract

The lipopolysaccharide (LPS) of Vibrio cholerae (V. cholerae) plays an important role in cholera disease and the induction of primary protection. In this study, we evaluate mice humoral immune response in intranasal and intraperitoneal administrated V. cholerae LPS. The results showed that the intranasal administration of LPS–chitosan nanoparticle induced the high level of antibodies compared to intraperitoneal injection of antigen without chitosan (P
