The purpose of this study was the combination of curcumin and ovalbumin in free form or encapsulated into PLGA NPs (polylactic co-glycolic acid nanoparticles) to enhance their sublingual immunotherapy (SLIT) efficiency in mouse model of rhinitis allergic. PLGA NPs containing curcumin (CUR), ovalbumin (OVA) or both were prepared by emulsion-solvent evaporation method and characterized. After sensitization of BALB/C mice with ovalbumin, SLIT with free or encapsulated formulations was carried out and immunological profiles were evaluated. SLIT treatment with all synthesized PLGA formulations lead to significantly decreased total IgE. The combination immunotherapy in the present of free form of curcumin or ovalbumin with encapsulated forms of the another substance (P.OVA-CUR 10 and P.CUR 5-OVA), showed the highest level of IFN-γ:IL-4 compared to other target groups. On the other hands, a significant increasment was observed in this ratio between these optimal groups and treated group with subcutaneous administration of OVA as the most commonly used method for immunotherapy. The study of nasal lavage fluid (NALF) showed significant decreased levels of total and eosinophil cell count in the traeted nano-formulation groups. The histopathological results of NAL were also like normal with no cellular infiltration and no inflammation in the optimal formulations. Therefore, using curcumin and nanoparticles with allergen can be considerd as potential immune modulatory agents. © 2020 Elsevier B.V.
