BACKGROUND Chronic inflammation is involved in the pathogenesis of chronic age-associated, degenerative diseases. Pro-inflammatory host responses that are deleterious later in life may originate from evolutionary selection for genetic variation mediating resistance to infectious diseases under adverse environmental conditions. METHODOLOGY/PRINCIPAL FINDINGS In the Upper-East region of Ghana w...

Interleukin-10–deficient (IL-10 / ) mice develop an IL-12–mediated intestinal inflammation in the absence of endogenous IL-10. The molecular mechanisms of the dysregulated IL-12 responses in IL-10 / mice are poorly understood. In this study, we investigated the role of nuclear factor– B (NFB) and signal transducers and activators of transcription 3 (STAT3) in lipopolysaccharide (LPS)–induced IL...

Interleukin (IL)-10 is a major anti-inflammatory cytokine that has been associated with obesity and type 2 diabetes. The three polymorphisms -1082G/A, -819C/T, and -592C/A in the IL10 promoter were reported to influence IL10 transcription. We investigated whether these polymorphisms were associated with type 2 diabetes and related traits in a cohort of Italian Caucasians comprising 551 type 2 d...

Debilitating infectious diseases caused by Chlamydia are major contributors to the decline of Australia's iconic native marsupial species, the koala (Phascolarctos cinereus). An understanding of koala chlamydial disease pathogenesis and the development of effective strategies to control infections continue to be hindered by an almost complete lack of species-specific immunological reagents. The...

The aim of the Malmö International Brother Study (MIBS) is to evaluate host genetic factors associated with the development of inhibitory antibodies in patients with hemophilia. Factor VIII gene mutations and genetic polymorphisms of the IL1beta, IL4, and IL10 genes, known to influence antibody production in autoimmune diseases, were analyzed in 164 patients (124 with severe, 26 with moderate, ...

Human UC-MSCs are regarded as an attractive alternative to BM-MSCs for clinical applications due to their easy preparation, higher proliferation and lower immunogenicity. However, the mechanisms underlying immune suppression by UC-MSCs are still unclear. We studied the mechanism of inhibition by UC-MSCs during the differentiation of monocytes into DCs and focused on the specific source and the ...

Runt piglets were used as a model for neonatal stress to test the hypothesis that stress during the pre-weaning period can alter adipokine gene transcription levels. Runts were selected by birth mass <1kg and compared to littermates (controls) of mean litter weight. Subcutaneous (SQ) and perirenal (PR) adipose tissues were collected at d1 (n=5), d7 (n=7) or d21 (n=9) of age. Real time PCR was u...

The recovery phase after kidney ischemia/reperfusion (IR) injury is often associated with the suppression of inflammation and the proliferation of tubular epithelial cells (TECs). The duration of this phase is often determined by the suppression of inflammation and the proliferation of TECs. Several lines of evidence suggest that IκB kinase α (IKKα) not only promotes the production of anti-infl...

BACKGROUND Approximately 10-14% of the clinically acknowledged pregnancies end with spontaneous abortion at Caucasian population. Possible immunologic causes of recurrent miscarriages have been extensively researched. The change in the cytokines balance synthesis in favor of those synthesized by Th2 cells with an increase of interleukin 6 (IL6) and interleukin10 (IL10) secretion is considered e...

There is now considerable evidence that host genetic factors are important in determining the outcome of infection with Mycobacterium tuberculosis (MTB). The aim of this study was to assess the role of several candidate genes in the variation observed in the immune responses to MTB antigens. In-vitro assays of T-cell proliferation, an in-vivo intradermal delayed hypersensitivity response; cytok...
