Th17 cells are key players in defense against pathogens and maintaining tissue homeostasis, but also act as critical drivers of autoimmune diseases. Based on single-cell RNA-seq profiling of pathogenic versus nonpathogenic Th17 cells, we identified protein C receptor (PROCR) as a cell surface molecule expressed in covariance with the regulatory module of Th17 cells. Although PROCR expression in...
مگس مینوز سبزی و صیفی Liriomyza sativae Blanchard ، از مهمترین آفات های گلخانه ای فضای باز، محسوب می شود. با توجه به توصیه کاربرد حشره کش تیوسیکلام جهت مدیریت آفت مزبور، در پژوهش حاضر، اثرات کشندگی زیرکشندگی(5/131:LC30، 1/87:LC20، 15/49:LC10 میلی گرم ماده موثره بر لیتر) حشره کش (اویسکت®SP50%) روی فراسنجه های زیستی این شرایط آزمایشگاهی مورد ارزیابی قرار گرفت. روش استفاده انجام آزمایشها غوط...
اینترلوکین17یک سایتوکاین پیش التهابی است که عمدتاً بوسیله سلول های th17 بیان می شود و بیان این سایتوکاین در ریزمحیط تومور نقش مهمی در افزایش سرعت رشد، آنژیوژنز و متاستاز سلول های سرطانی ایفا می کند. و با توجه به تاثیر تمرین استقامتی در کاهش عوامل التهابی و بهبود سرطان، هدف از پژوهش حاضر بررسی اثر 6 هفته تمرین استقامتی بر سطوح اینترلوکین17 در بافت تومور موش های ماده مبتلا به سرطان پستان می باشد. ...
OBJECTIVE CD4(+)CD25(+) regulatory T (Treg) cells and Th17 cells play important roles in peripheral immunity. Oxidized low-density lipoprotein (ox-LDL) is an instrumental factor in atherogenesis. However, the changes of Th17/Treg cells in patients with acute cerebral Infarction (ACI) and impact on Th17/Treg by ox-LDL are not clear. Here, we examined the balance of Th17/Treg in ACI patients and ...
IL17-producing (Th17) cells are a distinct lineage of T helper cells that regulate immunity and inflammation. The role of antigen-presenting cells in the induction of Th17 cells in humans remains to be fully defined. Here, we show that human dendritic cells (DCs) are efficient inducers of Th17 cells in culture, including antigen-specific Th17 cells. Although most freshly isolated circulating hu...
objective(s): this study aimed to investigate the role and the possible mechanisms involved in the immunoregulation of experimental periodontitis by th17/treg. materials and methods: experimental periodontitis was established by silk thread ligation with porphyromonasgingivalis daubing in the bilateral maxillary second molar of male sprague-dawley (sd) rats. alveolar bones were scanned by micro...
BACKGROUND The levels and clinical relevance of Th17 cells and other interleukin-17-producing cells have not been analyzed in chronic lymphocytic leukemia. The objective of this study was to quantify blood and tissue levels of Th17 and other interleukin-17-producing cells in patients with this disease and correlate blood levels with clinical outcome. DESIGN AND METHODS Intracellular interleuk...
Th17 and regulatory T (Treg) cells play opposite roles in autoimmune diseases. However, the mechanisms underlying their proper migration to inflammatory tissues are unclear. In this study, we report that these two T cell subsets both express CCR6. CCR6 expression in Th17 cells is regulated by TGF-beta and requires two nuclear receptors, RORalpha and RORgamma. Th17 cells also express the CCR6 li...
T helper type 17 (Th17) cells play an important pathogenic function in autoimmune diseases; their regulation, however, is not well understood. We show that the expression of a tumor necrosis factor receptor family member, death receptor 3 (DR3; also known as TNFRSF25), is selectively elevated in Th17 cells, and that TL1A, its cognate ligand, can promote the proliferation of effector Th17 cells....
