BACKGROUND Interleukin-10 (IL-10) is a negative regulator of immune responses and was previously shown to be expressed by human nasal endothelial cells, while the adhesion molecule MECA-79 plays a role in trans-endothelial migration of immune competent cells. In this study we investigate the relationship between endothelial IL-10 and MECA-79 expression to address the question whether immune com...

AIMS To determine whether the functional polymorphism -592C>A of the interleukin (IL)-10 gene (IL10) influences the development of alcoholic liver disease or alcoholism in alcoholic Spanish subjects. METHODS The -592C>A IL10 polymorphism was analyzed by the polymerase chain reaction and digestion with restriction enzymes in 257 male alcoholics [161 without alcoholic liver disease and 96 with ...

Objective:The aim of this study was to examined serum IL-10 levels in patients with HNSCC to elucidate its association with clinicopathologic parameters. Study design:Using an ELISA kit, we assessed the circulating levels of IL-10 in sera from 60 head and neck squamous cell carcinoma (HNSCC) patients as well as from 30 healthy controls. Results: The serum IL10 concentration in HNSCC patients wa...

BACKGROUND Pakistan ranks 7(th) globally in terms of tuberculosis (TB) disease burden (incidence 181/100000 pop./yr; prevalence of 329/pop./yr). Reports from different populations show variable associations of TB susceptibility and severity with cytokine gene polymorphisms. Tuberculosis clinical severity is multi-factorial and cytokines play a pivotal role in the modulation of disease severity....

BACKGROUND To investigate the gene expression levels of interleukin 10 (IL10), IL18, interferon gamma (IFNG), IFN-gamma receptor (IFNGR), C-reactive protein (CRP), and heat shock protein 70 (HSP70) in patients with active Behçet's uveitis. MATERIAL AND METHODS Forty patients with Behçet's disease diagnosed according to the International Study Group criteria and 30 healthy individuals were inclu...

An adequate immune and antioxidant response is a key to the resolution of sepsis. Heme oxygenase-1 (HMOX1) is a stress protein with a polymorphic (GT)n repeat in its gene promoter that regulates its expression in response to oxidative injury, such as that present in sepsis. HMOX1 is the rate-limiting enzyme of heme degradation, and the heme breakdown products, CO, Fe, and bilirubin, are conside...

OBJECTIVES To describe how certain peripheral immune parameters reflect the inflammatory alterations in patients with primary APS. METHODS Twenty-eight patients with newly diagnosed primary APS were studied. The control group included 26 patients with stable coronary disease and 38 healthy individuals. Peripheral blood lymphocyte subgroups were quantified, intracellular cytokines were measure...

BACKGROUND Immunological and clinical outcomes can vary considerably at the individual and population levels during both treated and untreated HIV-1 infection. Cytokines encoded by the interleukin-10 gene (IL10) family have broad immunomodulatory function in viral persistence, and several SNPs in the IL10 promoter sequence have been reported to influence pathogenesis or acquisition of HIV-1 inf...

Nitric oxide synthases (NOS) are important mediators of progrowth signaling in tumor cells, as they regulate angiogenesis, immune response, and immune-mediated wound healing. Ionizing radiation (IR) is also an immune modulator and inducer of wound response. We hypothesized that radiation therapeutic efficacy could be improved by targeting NOS following tumor irradiation. Herein, we show enhance...

Autoimmunity increases with aging indicative of reduced immune tolerance, but the mechanisms involved are poorly defined. In recent years, subsets of B cells with immunoregulatory properties have been identified in murine models of autoimmune disorders, and these cells downregulate immune responses via secretion of IL10. In humans, immature transitional B cells with a CD19(+) CD24(hi) CD38(hi) ...
