بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...
Aspergillus fumigatus is a fungal pathogen of major clinical importance. However, little is known about the role of human bronchial epithelial cells (HBECs) during A. fumigatus conidia induced inflammation. Here, we show that differentiated respiratory epithelial cells recognise inactivated resting conidia but not swollen conidia or hyphae, resulting in the induction of the interferon (IFN)-β s...
Macrophages respond to several subcellular products of Mycobacterium tuberculosis (Mtb) through TLR2 or TLR4. However, primary mouse macrophages respond to viable, virulent Mtb by pathways largely independent of MyD88, the common adaptor molecule for TLRs. Using microarrays, quantitative PCR, and ELISA with gene-disrupted macrophages and mice, we now show that viable Mtb elicits the expression ...
multiple sclerosis (ms) is an inflammatory, multifocal, immune-mediated disease of the central nervous system that women are at a higher risk to acquire than men. myxovirus resistance protein a (mxa) is used as a predictive marker of bioactivity of interferon-beta (ifn-β) therapy in ms patients. this study was undertaken in west of iran to investigate gender differences in the expression level ...
Macrophages are activated by unmethylated CpG-containing DNA (CpG DNA) via TLR9. IFN-gamma and LPS can synergize with CpG DNA to enhance proinflammatory responses in murine macrophages. Here, we show that LPS and IFN-gamma up-regulated Tlr9 mRNA in murine bone marrow-derived macrophages (BMM). The ability of LPS and IFN-gamma to induce Tlr9 mRNA expression in BMM was dependent on the presence o...
IFN-gamma is known to induce expression of Ia antigens on a variety of cell types. In the present study, this activity of IFN-gamma has been analyzed with a panel of 36 melanoma cell lines, normal melanocytes, and 97 cell lines representing a range of other differentiation lineages. 55% of the melanoma cell lines express Ia antigens in a constitutive manner without IFN-gamma induction. Of the 1...
OBJECTIVE Lysophosphatidylcholine (lysoPC) is abundant in atherosclerotic lesions and has potential immunomodulatory activities. This study is aimed to investigate effects of lysoPC on the interferon (IFN)-gamma-induced gene expression, focusing on T cell-directed CXC chemokines relevant to atherosclerosis. METHODS AND RESULTS Effects of lysoPC on the IFN gamma-induced gene expression of IFN-...
Background:The premature termination of high producer clones, which will be killed due to cell proliferation and proteins production antagonism, is one of the basic drawback in recombinant proteins technology. Furtheremore, it is supposed some toxic proteins like interferon which we intended to clone and express, inhibit host cells’ proliferation. So, it is necessary to tightly control IFN-γ pr...
Sclerotinia sclerotiorum is a phytopathogenic fungus which causes serious yield losses in canola. A pathogen inducible-promoter can facilitate the production of Sclerotinia-resistant transgenic canola plants. Inthis study, the “gain of function approach” was adopted for the construction of a pathogen-inducible promoter.The synthetic promoter technique was used, which involved the in...
The fact that adenoviral vectors activate innate immunity and induce type I IFNs has not been fully appreciated in the context of cancer gene therapy. Type I IFNs influence different aspects of human immune response and are believed to be crucial for efficient tumor rejection. We performed transcriptional profiling to characterize the response of cutaneous lymphomas to intralesional adenovirus-...
