زمینه و اهداف: مقاومت یا ایمنی سلولی در برابر عفونت توبرکولوز، بستگی به عملکرد لمفوسیت های T، که فعال کننده ماکروفاژهای از بین برنده مایکوباکتریوم های داخل سلولی اند، دارد. لمفوسیت های T از طریق ترشح شبکه ای از فاکتورهای محلول سایتوکاین ها، مسوول این روابط سلولی اند و طی سه دهه اخیر به طور گسترده مورد مطالعه قرار گرفته اند. اولین رخداد عفونت در میزبان با یک پاتوژن، پاسخ ایمنی ذاتی است که شامل ...
سابقه و هدف: یکی از راه های پیشگیری از هپاتیت b، مصون سازی توسط واکسیناسیون علیه این ویروس است. هدف از این مطالعه تعیین سطح پادتن ضد پادگن سطحی هپاتیت b (anti-hbs) و ارتباط آن با میزان اینترفرون گاما (ifn-γ) در پرسنل واکسینه شده و بررسی علل عدم پاسخ در برخی از این افراد می باشد. مواد و روش ها: این مطالعه مقطعی بر روی 130 نفر از پرسنل واکسینه بیمارستان شهید چمران انجام شد. نمونه ها از لحاظ س...
allergic rhinitis (ar) is one of the most common chronic diseases in the developed countries. this study was performed to investigate the effect of cpg-odn in alteration of t-helper (th)1/th2 balance of patients with ar treated with intranasal corticosteroids (incs) and antihistamines. peripheral blood mononuclear cells (pbmcs) of 20 patients with ar were isolated before and after 45 days thera...
To investigate the effects of carvacrol supplementation in rainbow trout induced by lipopolysaccharide (LPS), relative gene expressions levels of some pro-inflammatory cytokines and apoptosis markers in kidney and liver were measured. Fish with a mean weight of 44.71±1.33 g were studied using four different treatments with three replicates each. Inflammation and apoptosis were performed using L...
This work explores antiviral activity and gene induction properties of interferon gamma (IFN-γ) compared to type I IFN (IFNa1) in Atlantic salmon. IFN-γ protected salmon cells against infectious pancreatic necrosis virus (IPNV) induced cytopathic effect (CPE), reduced viral titers and inhibited synthesis of the viral structural protein VP3. Moreover, IFN-γ showed potent antiviral activity again...
Polystyrene nanoplastics (NP) are often found in aquatic environments. The accumulation of biota such as fish, shrimp, squid, shellfish, etc. can reduce the health humans who consume them. purpose this study was to observe red seaweed’s potential a source antioxidants improving immune system and reproductive rats (Rattus novergicus) exposed nanoplastics. Twenty-five norvegicus) were divided int...
background: leishmaniasis is a tropical disease that is endemic in some areas of iran, including east azerbaijan . ifn-γ is one of the cytokines that triggers cell-mediated immunity, thus initiating elimination of the infection. this case-control study was performed to investigate the association between the polymorphism of the ifn-γ gene at the +874a/t locus and visceral leishmaniasis (vl). me...
schizophrenia is a sophisticated mental disability which has affected nearly1.1% of people all over the world. according to recent researches, the key proteins triggered in the immune system are cytokines which might also be taking part in the pathogenesis of schizophrenia. the aim of this study was to evaluate the relationship between the -1082g/a and +874t/a polymorphisms of il-10 and ifn-γ g...
conclusions acute hev infection shows a pattern of th1-type immune response, and the direct significant positive correlation between the serum level of scd26 and ifn-γ in acute hev infected patients, suggests that the trend of scd26 levels is a valuable marker for predicting hepatic inflammation in hepatitis e. results the results showed a significant difference in ifn-γ and scd26 (p < 0.0001 a...
The pathology associated with Streptococcus pneumoniae meningitis results largely from activation of immune-associated pathways. We systematically investigated the production of IFN subtypes, as well as their influence on pathology, in a mouse model of S. pneumoniae meningitis. Despite the occurrence of a mixed IFN type I/II gene signature, no evidence for production or involvement of type I IF...
