background: β-thalassemia as a hereditary disease is defined as defective synthesis of   β-globin chains, resulting in erythropoiesis abnormalities and severe anemia. different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of   β-thalassemia. single nucleotide polymorphisms (snps) within the promoter region or other regulatory sequences ...

Carcinogen-induced skin tumorigenesis depends heavily on proinflammatory tumor-promoting processes. Here, we show that leukocytic Runx3 expression is central to the two-stage DMBA/TPA-induced skin tumorigenesis. Runx3-null mice were highly resistant to this process and concomitant ablation of Runx3 in dendritic and T cells fully recapitulated this resistance. Mechanistically, this resistance wa...

The effect of cycloheximide (CHX) on the mRNA expression of the cytokine-inducible, calcium-independent nitric oxide synthase (iNOS) was investigated in fetal hepatocytes stimulated with lipopolysaccharide (LPS) or pro-inflammatory cytokines. In the presence of CHX the LPS-dependent iNOS mRNA levels were reduced, whereas the response to pro-inflammatory cytokines was enhanced. Because iNOS tran...

Cytokine activation of gene expression can be mediated through signal transducer and activator of transcription (STAT) signaling pathways resulting in expression of target genes. Because many cytokines have important regulatory roles during early development, we wanted to ascertain whether STAT signaling was also active at this time and could therefore have important roles in mediating developm...

We have previously described inhibition of the synthesis of three acute-phase inflammatory cytokines in human and rat macrophages by acetate esters of rooperol, a dicatechol of plant origin. Analysing the mechanism of anticytokine activity of rooperol, we compared levels of TNFalpha, IL-1beta and IL-6 mRNAs in the human promonocytic U937 cell line pretreated with phorbol myristate acetate (PMA)...

Interleukin (IL)-12 has a broad range of activities including regulation of cytokine synthesis and selective promotion of Th1-type cell development. A shift from a Th1-type response to Th2-type has been suggested to be important in the pathogenesis of dengue hemorrhagic fever (DHF). This study was undertaken to investigate the possible role of IL-12 in this shift. A total of 76 patients with va...

BACKGROUND A test for diagnosis of active Tuberculosis (TB) from peripheral blood could tremendously improve clinical management of patients. METHODS Of 178 prospectively enrolled patients with possible TB, 60 patients were diagnosed with pulmonary and 27 patients with extrapulmonary TB. The frequencies of Mycobacterium tuberculosis (MTB) specific CD4(+) T cells and CD8(+) T cells producing c...

background: cytokines play a fundamental role in the regulation of immune responses in remission and/or relapsing of leishmaniasis. therefore, immunotherapy for the treatment of canine visceral leishmaniasis (cvl) has represented a principle approach in control of the infection. the present research aimed to evaluating the immunotherapeutic potential of a novel herbal immunomodulator drug (imod...

introduction: studies have shown the regulatory role of leptin in bone formation, its expression in adipose tissue as well as increased levels in circulation following the adminstration of inflammatory stimuli such as lipopolysaccharides (lps). however, there is little data evaluating the role of leptin in inflammatory periapical lesions. the aim of this study was to evaluate the presence and c...

background: the incidence of allergic and asthmatic diseases has been continuously increased in both industrial and developing countries. extracts from various known allergens are used for the diagnostic and therapeutic purposes. objective: to investigate the effects of an extract prepared from chenopodium album (ch.a.) pollen to induce allergic asthma in balb/c mice. methods: balb/c mice were ...
