چکیده

The influence of semen on immunity in sexually active women has been scarcely studied. The effect of human semen on production of messenger RNA (mRNA) for the anti-inflammatory TH2-related cytokine, interleukin-10 (IL-10), the 70 kDa heat shock protein (HSP70) and the pro-inflammatory TH1-related cytokine, interferon-gamma (IFN-gamma) was examined. Co-incubation of peripheral blood mononuclear cells (PBMC) from 10 women with a non-cytotoxic 1:50 dilution of semen lead to induction of IL-10 mRNA. Semen from each of seven different men tested induced IL-10 mRNA in PBMC. IL-10 protein was also released into the culture supernatant after PBMC-semen co-culture. Similarly, semen induced transcription of the HSP70 gene in PBMC obtained from 10 women. In contrast, semen did not induce IFN-gamma mRNA in any of the female PBMC donors. Furthermore, semen markedly inhibited IFN-gamma mRNA production without affecting cell viability in PBMC that were cocultured with phytohaemagglutinin, a potent IFN-gamma-inducing T-cell mitogen. Thus, human semen is both an inducer of an anti-inflammatory (TH2) immune response and an inhibitor of pro-inflammatory (TH1) cell-mediated immunity.

A 70-kilodalton recombinant heat shock protein of Candida albicans is highly immunogenic and enhances systemic murine candidiasis.

The 70-kDa recombinant Candida albicans heat shock protein (CaHsp70) and its 21-kDa C-terminal and 28-kDa N-terminal fragments (CaHsp70-Cter and CaHsp70-Nter, respectively) were studied for their immunogenicity, including proinflammatory cytokine induction in vitro and in vivo, and protection in a murine model of hematogenous candidiasis. The whole protein and its two fragments were strong indu...

Borrelia burgdorferi stimulates the production of interleukin-10 in peripheral blood mononuclear cells from uninfected humans and rhesus monkeys.

Heat-killed Borrelia burgdorferi spirochetes stimulate in vitro production of interleukin-10 (IL-10) at both mRNA and protein levels in peripheral blood mononuclear cells (PBMC) of uninfected rhesus monkeys. A concomitant down-modulation of IL-2 gene transcription was observed. Neither IL-4 nor gamma interferon gene expression was ostensibly affected by B. burgdorferi spirochetes. These phenome...

Lactobacilli and streptococci induce interleukin-12 (IL-12), IL-18, and gamma interferon production in human peripheral blood mononuclear cells.

Human peripheral blood mononuclear cells (PBMC) were stimulated with three nonpathogenic Lactobacillus strains and with one pathogenic Streptococcus pyogenes strain, and cytokine gene expression and protein production were analyzed. All bacteria strongly induced interleukin-1beta (IL-1beta), IL-6, and tumor necrosis factor alpha mRNA expression and protein production. S. pyogenes was the most p...

The production of molecular clones of Toxoplasma gondii-derived heat shock protein 70 kDa

Toxoplasmosis is a common and widespread infection in humans and many other species of warm–blooded animals. Toxoplasma gondii-derived heat shock protein 70 (Hsp70) may play an important role in the virulence of Toxoplasma gondii (T. gondii). In the present study, T. gondii Hsp70 was amplified by polymerase chain reaction (PCR) from the DNA of the T. gondiitachyzoite RH strain through the use o...

Interleukin-1 induces tumor necrosis factor (TNF) in human peripheral blood mononuclear cells in vitro and a circulating TNF-like activity in rabbits.

Recombinant human interleukin-1 (IL-1), injected into rabbits, induces the synthesis of endogenous IL-1. Also, IL-1 induces its own gene expression and synthesis in human peripheral blood mononuclear cells (PBMC). In this study, tumor necrosis factor-alpha (TNF-alpha) production by PBMC of 40 individuals stimulated with IL-1 alpha or IL-1 beta was determined by specific radioimmunoassay (RIA). ...
