results almost 8% of the personnel showed positive tst (over 10 mm) reaction while 29% of them had considerable t - cell reactivity against ppd in elispot assays. however, the esat - 6 reactivity was found only in one case of hcws. no correlation was found between the patterns of the reactions and the age or the duration of the employment or previous vaccination history of the participants. the...
Background and Objectives: Interferon-gamma is an important cytokine, which facilitates immunity against intracellular pathogens. Several factors, including genetic variations of cytokine-producing genes have been shown to influence the progression and severity of Hepatitis C virus (HCV) infection. Methods: Between January and D...
Salicylate enhanced the interferon-gamma-dependent activation of two transcription factors in a murine macrophage cell line: signal transducer and activator of transcription (STAT)1 and interferon-gamma-responsive factor 1. Salicylate alone did not activate these transcription factors. This enhancement was reflected by increased DNA-binding activities and was the consequence of prolonged tyrosi...
Background: One in every 250 newborns is exposed to antiepileptic drugs, inutero .The risk of congenital malformations in newborns, prenatally exposed to antiepileptic drugs (AEDs), is around 5% which is 2 to 2.5 times that of general population; while carbamazepine (CBZ) and valproate (VPA) still provide the treatment of choice in most forms of epilepsy, being efficacious in approximately two-...
atopic dermatitis (ad) is a heterogeneous disease with regard to clinical phenotype and natural history. we investigated t cell subtypes and cytokine responses in peripheral blood and skin lesions of ad patients with various sensitivities. immunological studies were performed in 27 subjects: 9 house dust mite (hdm)-sensitized; 6 subjects with sensitizations other than hdm; 7 non-allergic ad pat...
Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....
Human bronchial epithelial cells were treated in vitro with interferon-gamma or tumor necrosis factor-alpha to assess their effect on transepithelial ion transport. Short-circuit current measurements revealed that Na(+) absorption was markedly inhibited by interferon-gamma (10-1,000 U/ml). The cystic fibrosis transmembrane conductance regulator was also downregulated by interferon-gamma as evid...
Interferon-gamma mRNA activates the RNA-dependent protein kinase PKR, which in turn strongly attenuates translation of interferon-gamma mRNA. Unlike riboswitches restricted to noncoding regions, the interferon-gamma RNA domain that activates PKR comprises the 5' UTR and 26 translated codons. Extensive interferon-gamma coding sequence is thus dedicated to activating PKR and blocking interferon-g...
OBJECTIVE This study aims to evaluate the production of interferon-gamma and interleukin-10 by stimulated peripheral blood mononuclear cells isolated from patients with supraglottic laryngeal cancer before and after surgical treatment. METHODS Fourteen patients with advanced supraglottic laryngeal cancer were studied. Cultures of peripheral blood mononuclear cells isolated during the preopera...
Background: In recent years, numerous studies have addressed the role of other factors, especially the immune system, on developing diabetic retinopathy. Given the role of interferons in regulating immune system activities, the present study was conducted to investigate serum levels of interferon-gamma in patients with diabetic retinopathy. Materials and Methods: The present research was condu...
