Introduction The early secreted antigenic target 6-kDa protein (ESAT-6) plays an important role in immune protection against Tuberculosis. Owing to its great potential to increase immune response, chitosan can be considered as a suitable biodegradable polymer for intranasal administration. Methods The physiochemical properties of the nanoparticle were measured in vitro. Two weeks after the last intranasal administration, blood samples were collected and specific IgG, IFN-gama, and IL-4 levels were measured by ELISA. Results Chitosan nanoparticles containing ESAT-6 demonstrated stronger ability to induce IFN-gama, IL-4, and IgG antibody level than the control groups. Conclusion Administration of chitosan nanoparticles can be a suitable method to induce more appropriate immune responses against low inherent immunogenic tuberculosis proteins through intranasal routs.
