cytokines have been introduced as critical inducers in the development of th subpopulations.cytokines like il-10 are involved in inducing regulatory t cells such as type 1 regulatory t (tr1) cells cells. il-22 is a member of il-10 family of cytokines, and il-28a is a member of ifn-γ family. in this study, cord blood mononuclear cells (cbmc) from normal healthy individuals were isolated by ficol...

INTRODUCTION The lacrimal gland (LG) of the CD25-/- model of Sjögren's syndrome (SS) has high interleukin (IL)-17, IL-13 and interferon-gamma (IFN-γ) cytokines. The specific contribution of these cytokines to the onset and severity of dacryoadenitis in the CD25-/- mice has not been evaluated. METHODS CD25-/-IL-17A-/-, CD25-/-IL-17-/-IFN-γ-/- and CD25-/-IFN-γ-/- were used at 4, 8, 12, 16 weeks...

abstract pentavalent antimonials, as the 1st choice for the treatment of cutaneous leishmaniasis (cl), have various side effects. also, there are some reports of drug resistance. due to its safety, cryotherapy can be a good alternative or complementary treatment in cl. the aim of this study was to explore the possible systemic immunological mechanisms of cryotherapy besides its local effects in...

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 ...

Both Th1 and Th17 cells are important components of the immune response to Helicobacter pylori (Hp) in adults, but less is known about T cell responses to Hp during early childhood, when the infection is often acquired. We investigated Th1 and Th17 type responses to Hp in adults, children and infants in Bangladesh, where Hp is highly endemic. IL-17 and IFN-γ mRNA levels in gastric biopsies from...

To explore the feasibility of detecting salivary levels of IFN-γ, TNF-α, and sTNFR-2 from erosive oral lichen planus (ELP) patients for clinical application, 20 ELP patients were enrolled in the study as were 20 age-sex-matched controls. From all subjects, saliva level of the tested biomarkers was determined by ELISA. Salivary profiles were assessed in ELP patients by ELISA after being treated ...

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;...

background: cell mediated immunity, especially cytotoxic t cell responses against hiv-1 infection, plays a critical role in controlling viral replication and disease progres-sion. dna vaccine is a novel technology which is known to stimulate strong cellular immune responses. many dna vaccines have been tested for hiv infection but there is still no effective vaccine against this infection. cons...

the study of cytokines gene expression is quite important in various conditions of health and disease for the evaluation of clinical responses to new vaccination approaches. an absolute quantification is based on a calibration curve and production of standard controls to achieve more reliable results than in relative system. in this study we attempted to construct standard controls to evaluate ...
