Activation of airway epithelial cells by toll-like receptor agonists.
Toll-like receptors (TLR) play an important role in pathogen recognition and innate immunity. We investigated the presence and function of TLRs in the BEAS-2B airway epithelial cell line and primary bronchial epithelial cells. Standard real-time reverse transcriptase-polymerase chain reaction (RT-PCR) analysis and Taqman RT-PCR revealed that BEAS-2B cells express mRNA for TLR1-10. Several TLR l...
متن کاملToll-like receptors and airway inflammation.
The respiratory tract opens to the external environment at the oral side edge, and the other edge of the respiratory tract connects to the closed space (alveoli), and so to preserve the sterility in the terminal respiratory tract is critical for protection against pathogens. The recognition machinery for the invasion of microbes is indispensable for the preservation of the sterility in the lung...

مقدمه: آسم بیماری التهابی مجاری تنفسی است که عوامل ژنتیکی و محیطی مختلفی در آن نقش دارند.بیماری آسم را از جنبه های ایمونولوژیک می توان مورد بررسی قرار داد. ژن های مختلفی از سیستم ایمنی در ایجاد و تشدید آسم دخیل هستند. از جمله این ژن ها در سیستم ایمنی خانواده tlrs می باشد.از انجا که ایجاد چندشکلی ژنی در ژنها باعث تغییر در نحوه پاسخ سیستم ایمنی می گردد در این مطالعه به بررسی چند شکلی ژنی در خانوا...
15 صفحه اولToll and Toll-like receptors in Drosophila.
The Drosophila Toll receptor controls the immune response to Gram-positive bacteria and fungi by activating a signalling pathway partially conserved throughout evolution. The Drosophila genome encodes eight additional Toll-related receptors, most of which appear to carry out developmental rather than immune functions. One exception may be Toll-9, which shares structural and functional similarit...
متن کاملToll-like receptor 4, but not toll-like receptor 2, is a signaling receptor for Escherichia and Salmonella lipopolysaccharides.
Two members of the mammalian Toll-like receptor (TLR) family, TLR2 and TLR4, have been implicated as receptors mediating cellular activation in response to bacterial LPS. Through the use of mAbs raised against human TLR2 and TLR4, we have conducted studies in human cell lines and whole blood to ascertain the relative contribution of these receptors to LPS induced cytokine release. We show that ...
