Increased in vitro basophil activation in buffers of slightly elevated osmolarity in 2 cases of food-dependent exercise-induced anaphylaxis is presented. These data may suggest the importance of basophil activation degree in pathogenesis of this life threatening syndrome.
Background: People are exposed to more radiation than before with the application of radiation technology. Radiation is known to induce damage to cell structure, DNA, chromosomes and nucleus. In this study, we showed that CGJ extract can inhibit radiation-induced chromosomal damage in vivo and NLRP7 inflammasome activation in vitro, suggesting that the compound from CGJ can Be considered as a t...
primary sjögren's syndrome (pss) is a common autoimmune disease involving abnormal th17 activation. the aim of the current study was to investigate the immunosuppression effect of cyclosporine a (cys a), a potent immunosuppressor on the proliferation and activation of t cells, on the activation of th17 cells. blood samples from both inactive and active pss patients as well as healthy controls w...
سلول های بنیادی جنینی موشی ابزاری ارزشمند برای انجام مطالعات تمایز سلولی در شرایط in vitro هستند. تمایز سلولی فرایندی جدایی ناپذیر از رشد و نمو موجودات پرسلولی است. در این مطالعه نقش مسیر آپوپتوتیک میتوکندریایی و تغییرات سطح انرژی سلول در فرایند تمایز سلول های بنیادی موشی به کاردیومایوسیت و آپوپتوز بررسی شده است.
Objective(s): AMP-activated protein kinase/sirtuin 1 (AMPK/SIRT1) signaling pathway has been proved to be involved in the regulation of autophagy in various models. The aim of this study was to evaluate the effect of AMPK/SIRT1 pathway on autophagy after spinal cord injury (SCI). Materials and Methods:The SCI model was established in rats in vivo and the primary spinal cord neurons were subject...
در پژوهش حاضر با بررسی عصاره های متانولی، هگزانی و پروتئینی تعدادی از گیاهان، به وجود پپتیدها و مواد آلی ضد میکروبی در برخی از آن ها پی برده شد. به منظور امکان سنجی معرفی مواد موٍثره ی موجود در این گیاهان آزمایشات سمیت سلولی و اثر بر روی دو سایتوکاین سیستم ایمنی بدن در مطالعلت in vitro انجام شد. خواص آنتی اکسیدانتی عصاره های گیاهی نیر به دو روش بررسی شد.
Application of regulatory T cells (Tregs) in transplantation, autoimmunity and allergy has been extensively explored, but how Foxp3 and Treg stability is regulated in vivo is incompletely understood. Here, we identify a requirement for Deltex1 (DTX1), a contributor to T-cell anergy and Foxp3 protein level maintenance in vivo. Dtx1(-/-) Tregs are as effective as WT Tregs in the inhibition of CD4...
garlic, an antioxidant plant, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various proteins and this in turn has some effects on the structure of proteins and biochemical activity of them, the inhibition of this process seems very vital. for several years researchers in this field have done their best to recognize the antidiabetic compounds. th...
conclusions these results indicate that a. kellalensis extracts exert potent anti-rotaviral activity only after viral adsorption. the two extracts from a. kellalensis showed a good selectivity index. also these results suggest that extracts prepared from the flowers of a. kellalensis may be potential anti-rotaviral agents in vivo and be useful in veterinary medicine. background achillea kellale...
