Humoral and cell mediated immune responses to a pertussis containing vaccine in pregnant and nonpregnant women.

before vaccination. In contrast, proliferative and IFN-γ responses were increased to TT, PT, and FHA in nonpregnant women one month after vaccination, whereas in pregnant women only TT specific T cell ...

M.tuberculosis mutants lacking oxygenated mycolates show increased immunogenicity and protective efficacy as compared to M. bovis BCG vaccine in an experimental mouse model.

mycobacteria specific IFN-γ producing CD4 (+) and particularly CD8 (+) T cells could be detected by intracellular cytokine staining in mice vaccinated with the M.tb mutants. Finally, vaccination with either of ...

Immunogenicity of eight Mycobacterium avium subsp. paratuberculosis specific antigens in DNA vaccinated and Map infected mice.

Ag5, Ag6, MAP1637 c, MAP0388 and MAP3743 (identified by bioinformatic in silico screening of the Map genome). Strong, antigen-specific IFN-γ responses were induced in mice vaccinated with plasmid DNA ...

Partial reconstitution of the CD4+-T-cell compartment in CD4 gene knockout mice restores responses to tuberculosis DNA vaccines.

(IFN-gamma) responses to these DNA vaccines. The magnitude of the immune responses correlated with the extent of reconstitution of the CD4 +-T-cell compartment. Reconstituted mice vaccinated with DNA encoding ...

Induction of in vivo functional Db-restricted cytolytic T cell activity against a putative phosphate transport receptor of Mycobacterium tuberculosis.

we determined the immunodominant Th1-type CD4 (+) T cell epitopes in C57BL /10 mice, as measured by spleen cell IL-2 and IFN-gamma production. Furthermore, a potent IFN-gamma-inducing, D(b)-restricted ...

Culture filtrate specific H-2(b) restricted CD8+ T cells activated in vivo by Mycobacterium tuberculosis or bovis BCG recognize a restricted number of immunodominant peptides.

Mycobacterium tuberculosis infected mice with culture filtrate antigens leads to the appearance of a high percentage of D(b) restricted IFN gamma synthesizing CD8 + T cell blasts. Transporter associated protein-2 ...

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

contain a M. tuberculosis challenge infection. In addition, Ag85A DNA-vaccinated IFN-gamma gene knockout mice produced Ag85-specific antibodies and IL-2 but died rapidly following a M. tuberculosis ...

Characterization of the culture filtrate-specific cytotoxic T lymphocyte response induced by Bacillus Calmette-Guérin vaccination in H-2b mice.

that they use the degranulation pathway (secretion of perforins and granzymes) as the main lytic mechanism of cytotoxicity and also secrete IFN-gamma upon incubation with CF-pulsed macrophages. The in ...
