A CCHFV DNA vaccine protects against heterologous challenge and establishes GP38 as immunorelevant in mice

Bivalent DNA Vaccination with Genes Encoding Leishmania major Cysteine Proteinases Type I and II Protects Mice Against Infectious Challenge

Smallpox DNA vaccine delivered by novel skin electroporation device protects mice against intranasal poxvirus challenge.

Previously, we demonstrated that an experimental smallpox DNA vaccine comprised of four vaccinia virus genes (4pox) administered by gene gun elicited protective immunity in mice challenged with vaccinia virus, and in nonhuman primates challenged with monkeypox virus (Hooper JW, et al. Smallpox DNA vaccine protects nonhuman primates against lethal monkeypox. J Virol 2004;78:4433-43). Here, we re...

A novel recombinant DNA vaccine encoding Mycobacterium tuberculosis ESAT-6 and FL protects against Mycobacterium tuberculosis challenge in mice

Mycobacterium tuberculosis 6-kDa early secretory antigenic target (ESAT-6) is a dominant target antigen for cell-mediated immunity in the early phase of tuberculosis. The fms-like tyrosine kinase 3 ligand (FL) that induces potent immune response has been used as an adjuvant in vaccine development. In this study, a new recombinant plasmid (pIRES-epitope-peptides-FL) encoding three T cell epitope...

Immunization with a DNA vaccine cocktail induces a Th1 response and protects mice against Mycobacterium avium subsp. paratuberculosis challenge.

Several antigens of Mycobacterium avium subsp. paratuberculosis have been studied as vaccine components and their immunogenicity has been evaluated. Previously, we reported that 85 antigen complex (85A, 85B, and 85C), superoxide dismutase (SOD), and 35kDa protein could induce significant lymphocyte proliferation as well as the elaboration of Th1-associated cytokines including interferon gamma (...

Rationalized design of a mucosal vaccine protects against Mycobacterium tuberculosis challenge in mice.

Pulmonary tuberculosis (TB) caused by Mycobacterium tuberculosis (Mtb) is a leading cause of global morbidity and mortality. The only licensed TB vaccine, Mycobacterium bovis bacillus Calmette-Guerin (BCG), has variable efficacy in protecting against pulmonary TB. Thus, the development of more effective TB vaccines is critical to control the TB epidemic. Specifically, vaccines delivered through...
