background and aims: chronic hbv infection is one of the most common viral infections in worldwide which many factors such as genetic factors are involved in pathogenesis of disease. gamma interferon (ifn-γ) and its receptor (infgr) play a critical role in the immune response to hbv infection. single nucleotide polymorphisms (snps) are effective on level of gene expression, the aim of this stud...
Abstract Background and objectives: Interferon-Gamma and interferon Gamma receptor (IFNγ ⁄ IFNγR1) are the main genes associated with susceptibility to tuberculosis. We aimed at studying on interferon-Gamma Gene polymorphism(- 56 C/T) in people suffered from tuberculosis (TB). Material and Methods: In this case-control study, the subjects were 62 individuals with TB and 74 hea...
Background and Objective: The aim of the present study was to express recombinant human interferon-gamma in Leishmania tarentolae. The Leishmania expression system represents the combination of easy handling known from bacterial expression systems with the potential of a eukaryotic protein expression, folding and modification system. The trypanosomatid protozoan host Leishmania tarent...
we have reviewed the medical records of 40 patients with disseminated (bacille calmette-guerin) bcg from 1996 to 1999 in the immunology department of the children hospital, medical center, tehran university. these patients are divided in to 3 groups: 1. patients who had disseminated (bacille calmette-guerin) bcg after vaccination and their diagnosis was chronic granulomatous disease. 2. patient...
objective(s) previous studies have demonstrated that the nitric oxide (no) dependent death of murine peritoneal macrophages activated in vitro with ifn-g and lps is mediated through apoptosis. in the present study, we investigated the synergistic effect of lps, ifn-g and iron on no production and apoptosis. materials and methods after determination of iron cytotoxicity, the peritoneal macrophag...
background cutaneous leishmaniasis is a health problem in the world. lesions should be treated on cosmetically or functionally important sites, such as the face and hands. cantharidin is a terpenoid compound produced naturally by beetles of meloidae and oedemeridae families. objectives the current study aimed to investigate the effect of cantharidin on cutaneous leishmaniasis (cl) lesions and i...
results the frequencies of the aa, at, and tt genotypes were 31%, 51%, and 18% in the chronic hbv patient group, and 40%, 45%, and 15% in the healthy control group, respectively. however, a lack of association of the + 874 polymorphism in the ifn-γ gene of those with chronic hbv infection was found. evaluation of hbv association with this polymorphism was significant under the dominant genetic ...
it is now well documented that interferon gamma (ifn-γ) is the indispensable cytokine for inducing protective immunity against experimental and human cutaneous leishmaniaisis. the importance of ifn-γ receptor (ifn-γr) has also been studied. in the present study, we made attempts to find out whether l. major infection is able to alter the expression of ifn-γr in vivo. in addition, we studied the...
objective(s):experimental allergic encephalomyelitis (eae) is an autoimmune disease validated as animal model of multiple sclerosis (ms). administration of genistein, a phytoestrogenic component of soy, to mice at the onset of eae is known to attenuate the clinical signs of the disease. the potential effects of genistein on established eae is less studied. in the current study, we aimed to comp...
