To study the interaction of lymphocytes and macrophages in the control of extracellular matrix turnover, we determined the effects ofseveral solubleT cell products on mononuclear phagocyte production of metalloproteinases. Cytokines including IL2, IL4, IL-6, tumor necrosis factor a (TNFa), GM-CSF, and IFN-gamma were each tested for capacity to modulate macrophage metalloproteinase and tissue in...
Antibody-antigen (Ab-Ag) recognition is the primary event at the basis of many biosensing platforms. In label-free biosensors, these events occurring at solid-liquid interfaces are complex and often difficult to control technologically across the smallest length scales down to the molecular scale. Here a molecular-scale technique, such as single-molecule force spectroscopy, is performed across ...
Although cell-to-cell variability has been recognized as an unavoidable consequence of stochasticity in gene expression, it may also serve a functional role for tuning physiological responses within a cell population. In the immune system, remarkably large variability in the expression of cytokine genes has been observed in homogeneous populations of lymphocytes, but the underlying molecular me...
background: considering the role of t cells in the pathogenesis of periodontitis, the purpose of this study was to compare the amount of ifnγ, il4 and il17 in advanced periodontal lesions with healthy gum areas to determine each th1, th2 and th17 cells activity in comparison with each other and finally, to compare the value and the role of humoral, cell mediate and autoimmune responses. met...
مقدمه : بیماری آلزایمر به عنوان شایعترین عامل دمانس یا زوال عقل در دوران میانسالی و پیری، با نقص در فعالیت های شناختی از جمله عدم توانایی در سخن گفتن، عدم تشخیص افراد و اشیاء با وجود سالم بودن حواس، از دست دادن حافظه، از دست دادن توانایی انجام حرکات هدفدار و تغییرات شخصیتی همراه است. محققان با انجام آزمایشهای متعدد دریافتند که سیتوکین های پیش التهابی و کموکین ها در پاتوژنز چندین نوع از نواقص نو...
the study of cytokines gene expression is quite important in various conditions of health and disease for the evaluation of clinical responses to new vaccination approaches. an absolute quantification is based on a calibration curve and production of standard controls to achieve more reliable results than in relative system. in this study we attempted to construct standard controls to evaluate ...
OBJECTIVE The progression of joint destruction in rheumatoid arthritis (RA) is determined by genetic factors. Changes in IL4 and IL4R genes have been associated with RA severity, but this finding has not been replicated. This study was undertaken to investigate the association between IL4- and IL4R-tagging single-nucleotide polymorphisms (SNPs) and the progression rate of joint damage in RA in ...
