Abstract Cytokines have a vital role in reproductive immune environment during the postpartum period. Previous data evaluated uterine and vaginal cytokine concentrations prior to insemination; however, was unable correlate these with plasma concentrations. The objective of this study determine relationships between uterine, vaginal, pro- anti-inflammatory beef cows timed artificial insemination...

BACKGROUND Diagnosis and treatment monitoring of patients with tuberculosis remain challenging. OBJECTIVE We have evaluated whether Mycobacterium-specific interferon (IFN)-γ and interleukin (IL)-2 bifunctional cytokine immune response assays improve the diagnosis of and correlate to treatment response in pulmonary tuberculosis. METHODS Early secretory antigenic target (ESAT)6/culture filtra...

conclusions our findings indicate that heterogeneity at +2109 locus of ifn-γ gene but not at +874 locus could interfere with successful therapy in patients infected with hcv genotype 1. results of 158 patients, 110 (69.5%) subjects achieved svr and 48 (30.5%) subjects did not respond to therapy. the frequency of aa genotype (p = 0.001; or: 11.2; ci: 2.26-63.21) and a allele (p = 0.01; or: 3.23;...

Preeclampsia is a "disease of theory" because the cause and pathophysiology preeclampsia still uncertain. In invasion trophoblast cells does not occur completely, spiral arteries undergo remodeling so it has component muscle elastic tissue, in addition to endothelial dysfunction characterized by reduced relaxation factor increased contraction resulting ischemia placenta The end result hypoxia, ...

African trypanosomes cause fatal infections in both humans and livestock. Interferon gamma (IFN-γ) plays an essential role in resistance to African trypanosomes. However, increasing evidence suggests that IFN-γ, when excessively synthesized, also induces immunopathology, enhancing susceptibility to the infection. Thus, production of IFN-γ must be tightly regulated during infections with African...

IFN-γ is crucial for protection against Mycobacterium tuberculosis. miR-29 was recently shown to non-redundantly inhibit IFN-γ. Here, we investigated IFN-γ and miR-29a expression dynamics of CD4(+) T cells from patients during active tuberculosis (TB) (n = 32) and in household contacts who were latently M. tuberculosis infected (n = 19) from Ghana. Whereas M. tuberculosis-specific IFN-γ express...

Interferon (IFN)-γ has been implicated in restenosis, however its precise role in the pathophysiology of neointimal formation following angioplasty is unclear, as it has been shown to both promote and inhibit neointimal formation. Dietary-induced hypercholesterolemia enhances injury-mediated neointimal formation, associated with increased systemic inflammation and serum IFN-γ. This study examin...

Brucella abortus is a facultative intracellular bacterial pathogen that causes abortion in domestic animals and undulant fever in humans. IFN-γ, IL-12, and CD8+ T lymphocytes are important components of host immune responses against B. abortus. Herein, IFN-γ and IL-12/β2-microglobulin (β2-m) knockout mice were used to determine whether CD8+ T cells and IL-12-dependent IFN-γ deficiency would be ...

Neutrophils are an emerging cellular source of IFN-γ, a key cytokine that mediates host defense to intracellular pathogens. Production of IFN-γ by neutrophils, in contrast to lymphoid cells, is TLR- and IL-12-independent and the events associated with IFN-γ production by neutrophils are not understood. In this study, we show that mouse neutrophils express IFN-γ during their lineage development ...
