زمینه و هدف: پژوهش ها نشان می دهد که لیپوپلی ساکارید ( LPS ) بعنوان مهمترین ساختمان آنتی ژنیکی سویه های صاف بروسلا ،کاندیدای مناسبی برای طراحی واکسن های زیرواحدی است. از طرفی کاربرد ادجوانت های با منشا میکروبی در القاء پاسخهای ایمنی سبب طراحی نسل جدید واکسنهای زیرواحدی شده است که نمونه آن وزیکول غشای خارجی ( Outer Membrane Vesicle: OMV ) نیسریا مننژیتیدس است. وزیکول غشای خارجی باعث افزایش عیا...
Objective: The interleukin-12/interferon-γ (IL-12/IFN-γ) pathway is the most validated cytokine regulating Mycobacterium tuberculosis infection. role of IL-12/IFN-γ axis in protecting against (TB) exhibited people having mutations genes encoding these cytokines. We aimed to study serum levels IL-12 and IFN-γ pediatric their correlation with clinical microbiological features. Material Methods: A...
Peripheral, Placental and Cord Cytokines Profile in Spontaneous Labor and Elective Caesarean Section
Background: Cesarean section delivery can lead to much maternal morbidity. Different cytokines have been reported to be influenced by the mode of delivery. Objective: To investigate the influence of mode of delivery on maternal, placental and cord sera of interferon gamma (IFN-γ), interleukin-4 (IL-4) and interleukin-10 (IL-10) levels. Methods: These three cytokines were measured using ELISA in...
the role of transforming growth factor (tgf)-β1, interferon (ifn)-γ, interleukin (il)-2, il-3, and il-6 in the pathogenesis of alzheimer's disease (ad) has long been reported in literature. in this case-control study, the concentrations of these cytokines in altered t lymphocytes, as well as serum vitamin b12, have been compared in terms of factors such as, age, the clinical course and the pati...
Background: Malassezia furfur is alipophilic yeast that causes skin disease. Objective: To evaluate the level of IL-10, IFN-γ and IL-12P70 in co-incubation of M. furfur grown on different forms of natural oils with PBMCs of healthy individuals. Methods: PBMCs were obtained from blood samples of normal volunteers. M. furfur was cultured in different culture media containing almond oil, fish oil,...
Background: IBD is a chronic inflammatory condition associated with damage to the intestinal mucosal barrier. Supplementation of yacon tubers has been known to give positive effect in intestinal health. Therefore, we conducted the study to investigate the effect of yacon tuber powder on Th1 activation pathway by evaluating IFN-γ levels and the number of goblet cells in the colon of colitis mous...
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...
The aim of the present study was to determine seroprevalence of Toxoplasma gondii infectionin stray cats and correlation with oocyst shedding and IFN-γ concentration. From April to August 2016, one hundred fifty-nine stray cats were captured from various localities in Mashhad area. The blood and fecal samples were collected from each cat. The serum samples were examined to detect antib...
Introduction: Leishmaniasis is one of the common diseases between humans and animals. The present study was to investigate the expression pattern of pro-inflammatory genes in different stages of cutaneous leishmaniasis progression in order to provide a standard framework for diagnosis of various stages of the disease. Methods: In this experimental study, 2×106 Leishmania major were injected in...
Abstract Background and Objectives Antibody against RhD antigen is important in blood transfusion and clinical medicine. Therefore, in this study, the effective factors in the optimization of in vitro immunization to achieve immunized lymphocytes that produce antibodies were evaluated to obtain antibodies against RhD antigen in the culture medium. Materials and Methods In an experimental study...
