Biochemical and immunological characterization of a cpn60.1 knockout mutant of Mycobacterium bovis BCG1265

mutant is less persistent in lungs and, to a lesser extent, in spleen, but it induces a comparable mycobacteria-specific IFN-gamma production and protection against Mycobacterium tuberculosis H37R ...

IFN-gamma expression and infectivity of Toxoplasma infected tissues are associated with an antibody response against GRA7 in experimentally infected pigs36581

conventional 5-week-old seronegative pigs, an IFN-gamma response was detected in the blood, with a kinetic profile that followed the magnitude of the GRA7 antibody response. Antibody responses to GRA1, MIC3 and ...

Two alternative inocula to reproduce bluetongue virus serotype 8 disease in calves.

between IL-4 and IFN-γ expression. Both tested inocula are presented as valid alternative to the use of wild type infectious blood in the study of the pathogenesis of BTV-8 or the efficacy of current and ...

Evaluation of the immune response induced by DNA vaccine cocktail expressing complete SAG1 and ROP2 genes against toxoplasmosis34034

its immune response and protective efficacy in comparison with single-gene vaccines and control groups. We immunized BALB /c mice intramuscularly three times. DNA cocktail elicited IgG and IFN ...

Anti-TNF-alpha therapy does not ameliorate disease in a model of acute virus-endotoxin mediated respiratory disease in pigs36852

infiltration or induction of IFN-alpha, IL-1, IL-6, IL-12 and TNF-alpha in BAL were detected. Subsequently, the ability of etanercept to block porcine TNF-alpha and its effect on the above mentioned parameters ...

The positive adjuvant effect of chitosan on antigen-specific cell-mediated immunity after chickens vaccination with live Newcastle disease vaccine.

free (SPF) chickens. It was shown that chitosan enhanced the antigen-specific cell-mediated immune response in the spleen. New protocols were developed to measure the chicken IFN gamma production after ...

Functional characterization of in vivo effector CD4(+) and CD8(+) T cell responses in acute Toxoplasmosis: an interplay of IFN-gamma and cytolytic T cells36873

GRA7-specific T cells from infected mice were IFN-gamma(+) FasL(-) CD107 (-). No IFN-gamma or lytic markers were observed against ROP2. In cocktail DNA vaccinated C3H /HeN mice, the response was restricted to ...

Functional characterization of in vivo effector CD4(+) and CD8(+) T cell responses in acute Toxoplasmosis: an interplay of IFN-gamma and cytolytic T cells.

and CD8 (+) T cells were recruited to the peritoneal cavity after i.p. challenge with these syngeneic cell lines. GRA1 and GRA7-specific T cells from infected mice were IFN-gamma(+) FasL(-) CD107 (-). ...

Prior infection with an H1N1 swine influenza virus partially protects pigs against a low pathogenic H5N1 avian influenza virus.

H1N1 infection induced high levels of H5N1 cross-reactive NI antibodies. Cross-reactive CMI was demonstrated by measurements of lymphoproliferation and IFN-gamma secretion after in vitro restimulation of ...
