In the aged brain, synaptic plasticity and memory show increased vulnerability to impairment by the inflammatory cytokine interleukin 1β (IL-1β). In this study, we evaluated the possibility that synapses may directly undergo maladaptive changes with age that augment sensitivity to IL-1β impairment. In hippocampal neuronal cultures, IL-1β increased the expression of the IL-1 receptor type 1 and ...
پژوهش حاضر اثرات تمرین هوازی بر فاکتورهای التهابی قلب موشهای درمعرض ذرات کربن سیاه را موردبررسی قرار داده است. در این پژوهش، 24 سر موش نر بالغ نژاد ویستار 10 هفتهای با میانگین وزنی 97/26±29/279 گرم به چهار گروه ششتایی تقسیم شدند که عبارت هستند از: گروه کنترل (بدون تمرین هوازی و قرارگیری درمعرض PM10)، گروه تمرین هوازی (پنج جلسه در هفته و بهمدت چهار هفته)، گروه قرارگیری درمعرض PM10 کربن ...
Bacterial biofilms resist host defenses and antibiotics partly because of their decreased metabolism. Some bacteria use proinflammatory cytokines, such as interleukin (IL)-1β, as cues to promote biofilm formation and to alter virulence. Although one potential bacterial IL-1β receptor has been identified, current knowledge of the bacterial IL-1β sensing mechanism is limited. In chronic biofilm i...
LPS activates platelets through TLR4, aiding productive sepsis, with stimulated splicing and translation of stored heteronuclear pro-IL-1β RNA. Although the IL-1R type 1 (IL-1R1) receptor for IL-1 shares downstream components with the TLR4 receptor, platelets are not known to express IL-1R1, nor are they known to respond to this cytokine. We show by flow cytometry and Western blotting that plat...
سابقه و هدف: سیگار یکی از مهم ترین ریسک فاکتورها در پاتوژنز و پیشرفت بیماری های پریودنتال می باشد که می تواند در پروسه های التهابی توسط تاثیر بر سیتوکین های پیش التهابی مداخله ایجاد کند. il-1β یک سیتوکین پیش التهابی قوی است که در لثه موجود بوده، با پریودنتیت رابطه دارد و در حقیقت مولکول کلیدی در پاتوژنز پریودنتیت است. هدف از انجام این تحقیق تعیین رابطه میان مصرف سیگار و غلطت il-1β در مایع شیار ...
BACKGROUND Multiple sclerosis (MS) has been mainly attributed to white matter (WM) pathology. However, recent evidence indicated the presence of grey matter (GM) lesions. One of the principal mediators of inflammatory processes is interleukin-1β (IL-1β), which is known to play a role in MS pathogenesis. It is unknown whether IL-1β is solely present in WM or also in GM lesions. Using an experime...
cytokines play a part in pathogenesis of periodontitis via inflammation phenomenon. aggressive periodontitis (agp) is a multifactorial disease resulting in rapid tooth loss due to severe destruction of tooth supporting apparatus. recently, researchers have focused on genetic susceptibility of periodontitis through investigating the gene variations of cytokines and other components of immune res...
introduction: knee osteoarthrosis is one of the most debilitating diseases. prolotherapy includes intraarticular injection of various drugs to decrease inflammation. injection of intradiscal o2-o3 has reduced pain and disability of patients with low back pain due to prolapsed lumbar disk. objective: to compare the effect of intraarticular injection of ozone and steroids in improvement of clinic...
Abstract Aims: To investigate the effect of Myrtenol, the active ingredient of Myrtle, on the oxidant and anti-oxidant indices and cytokines in the allergic asthma. Methods: Allergic asthma was induced by ovalbumin (OVA) sensitization and inhalation in four groups of rats; Control, Asthma, Asthma+Dexamethasone and Asthma+Myrtenol. Myrtenol (50mg/kg) or Dexamethasone (2.5mg/kg) was a...
