Mapping of murine Th1 helper T-Cell epitopes of mycolyl transferases Ag85A, Ag85B, and Ag85C from Mycobacterium tuberculosis.

Ag85C from M. tuberculosis. Th1-type spleen cell cytokine secretion of interleukin-2 (IL-2) and gamma interferon (IFN-gamma) was analyzed in response to purified Ag85 components and synthetic overlapping ...

Improved tuberculosis DNA vaccines by formulation in cationic lipids.

Phosphatidylethanolamines Spleen T-Lymphocytes, Cytotoxic Th1 Cells Tuberculosis Vaccination Vaccines, DNA Abstract: Mice were vaccinated with plasmid DNA (pDNA) encoding antigen 85A (Ag85A), Ag85B, or PstS-3 from ...

Dynamics of immune cell infiltration in the caecal lamina propria of chickens after neonatal infection with a Salmonella enteritidis strain.

Infections, Animal Spleen T-Lymphocytes Abstract: Dynamics of leucocyte infiltration and bacterial invasion in the caecal wall were studied after oral infection of 2-day-old chicks with Salmonella enterica ser. ...

Improved immunogenicity and protective efficacy of a tuberculosis DNA vaccine encoding Ag85 by protein boosting.

interleukin-2 and gamma interferon (IFN-gamma) response in spleen two- to fourfold. Further, intracellular cytokine analysis by flow cytometry also showed an increase in IFN-gamma-producing CD4 (+) T cells in ...

CD4+ T cells contain Mycobacterium tuberculosis infection in the absence of CD8+ T cells in mice vaccinated with DNA encoding Ag85A.

spleen and lungs 4 weeks post-infection. In contrast, mice lacking CD4 + T cells were neither sensitized by the Ag85A DNA vaccine to produce Ag85-specific antibodies or Th1 type cytokines nor did they ...

Tuberculosis DNA vaccine encoding Ag85A is immunogenic and protective when administered by intramuscular needle injection but not by epidermal gene gun bombardment.

Interleukin-4 Lung mice Mice, Inbred BALB C Mice, Inbred C57BL Mycobacterium tuberculosis Spleen T-Lymphocytes, Cytotoxic Tuberculosis Vaccination Vaccines, DNA Abstract: Immunogenicity and protective efficacy of ...

Classical swine fever virus: a ring test to evaluate RT-PCR detection methods.

viral RNA representative of seven different genetic subtypes of CSFV. The other set comprised 40 clinical samples containing tonsil, spleen, whole blood or serum from a pig that had been experimentally ...

Cloning of the gene encoding a 22-kilodalton cell surface antigen of Mycobacterium bovis BCG and analysis of its potential for DNA vaccination against tuberculosis.
