Basic mechanisms of DNA-raised antibody responses to intramuscular and gene gun immunizations.
DNA-raised antibody (Ab) responses have been compared for the dependence on CD4+ and CD8+ cells, the longevity of functional antigen (Ag) expression, and the nature of the Ag-presenting cell after intramuscular (i.m.) and gene gun inoculations. A plasmid expressing the hemagglutinin (HA) glycoprotein of influenza virus was used for immunizations of BALB/c mice. Intramuscular and gene gun-raised...
متن کاملChoice and Design of Adjuvants for Parenteral and Mucosal Vaccines
The existence of pathogens that escape recognition by specific vaccines, the need to improve existing vaccines and the increased availability of therapeutic (non-infectious disease) vaccines necessitate the rational development of novel vaccine concepts based on the induction of protective cell-mediated immune responses. For naive T-cell activation, several signals resulting from innate and ada...
متن کاملEnhancement of DNA vaccine potency through coadministration of CIITA DNA with DNA vaccines via gene gun.
Administration of DNA vaccines via gene gun has emerged as an important form of Ag-specific immunotherapy. The MHC CIITA is a master regulator of MHC class II expression and also induces expression of class I molecules. We reasoned that the gene gun administration of CIITA DNA with DNA vaccines employing different strategies to improve MHC I and II processing could enhance DNA vaccine potency. ...
متن کاملSystemic Administration of CpG Oligodeoxynucleotide and Levamisole as Adjuvants for Gene-Gun-Delivered Antitumor DNA Vaccines
DNA vaccines showed great promise in preclinical models of infectious and malignant diseases, but their potency was insufficient in clinical trials and is needed to be improved. In this study, we tested systemic administration of two conventional adjuvants, synthetic oligodeoxynucleotide carrying immunostimulatory CpG motifs (CpG-ODN) and levamisole (LMS), and evaluated their effect on immune r...
متن کاملA Comparative Study of Protective Immunity Provided by Oral, Intranasal and Parenteral Canine Bordetella bronchiseptica Vaccines
The present study was designed to determine if an oral live Bordetella bronchiseptica vaccine protects dogs from developing signs of respiratory disease after challenge with virulent Bordetella bronchiseptica. The study was also designed to compare the level of protection induced by the oral vaccine with the protection provided by an intranasal live vaccine and an injected killed vaccine. Forty...
