This study was to prepare the chitosan-pDer p 2 nanoparticles and to investigate the effect of chitosan-DNA nanoparticles on immune response in mice by oral delivery of chitosan-DNA nanoparticles. The nanoparticles were synthesized by complexing chitosan with plasmid DNA. The DNA was fully complexed into chitosan-DNA nanoparticles, suggesting a 100% encapsulation efficiency. Chitosan-DNA complex renders a significant protection of the plasmid. No effect on cell viability was observed in both cell types and average cell viability over 100% was obtained. Oral gene delivery with chitosan-DNA nanoparticles can generate a higher level expression of gene in vivo. Oral chitosan-pDer p 2 nanoparticles in BALB/c mice can induce IFN-gamma in serum and prevent subsequent sensitization of Th2 cell-regulated specific IgE responses. The data indicate that the oral administration of chitosan-pDer p 2 nanoparticles results in the expression of Der p 2 in the epithelial cells of both stomach and small intestine and the induction of Th1-type immune response. |
