| Abstract/Description: | DNA vaccine is an important tool to elicit both humoral and cellular immunity. Present study investigates mucosal immune response of Labeo rohita (15 ? 04 g) to plasmid DNA (pDNA) vaccine macromolecule complexed with nanoparticles (NPs). Poly lactic-co-glycolic acid (PLGA), Chitosan (Chit) and PLGA-Chit-NPs were synthesized by double emulsion solvent evaporation method. Synthesized NPs were complexed with pDNA (pGPD + IFN) vaccine construct. Size and zeta potential of PLGA-NPs, Chit-NPs and PLGA-Chit-NPs-pDNA complex were recorded to be 120 nm and +0.5 mV, 117 nm and +32 mV, 189 nm and +11 mV, respectively. Immunization by immersion was carried out in two groups receiving PLGA-Chit-NPs-pDNA (T1) and PLGA-NPs-pDNA (T2) respectively. After immersion, samples were collected on 0, 2, 4, 7, 15 and 30 days from mucosa-associated lymphoid tissues (MALT) for mRNA expression studies of IgM, IgD and IgZ using qRT-PCR. Significant up-regulation of the mRNA expression of IgM, IgD, and IgT were observed in MALT in immunized fish compared to control. After 30 days post-immunization fish were infected with a virulent strain of Edwardsiella tarda. The highest relative percentage survival was observed in T1 (64.7%) compared to T2. The study showed better efficiency of pDNA-PLGA-Chit-NPs compared to pDNA-PLGA-NPs for inducing adaptive mucosal immunity in fish. |
