Mouse milk fat globule epidermal growth factor 8 (MFG-E8), which is secreted by a subset of activated macrophages, binds to apoptotic cells by recognizing phosphatidylserine and promotes their engulfment. Many apoptotic cells are left unengulfed in the germinal centers of the spleen in MFG-E8(-/-) mice, and these mice develop an autoimmune disease resembling human systemic lupus erythematosus (...
OBJECTIVE MFG-E8 (also called lactadherin and SED1) is a secreted glycoprotein that has been previously implicated in enhancement of vascular endothelial growth factor-dependent angiogenesis. Major sources of MFG-E8 in vivo and precise mechanisms of MFG-E8 action remain undetermined. The objective of this study was to identify important sources of MFG-E8 in vivo and further elucidate the role(s...
Throughout this paper, k denotes a field of characteristic 0. We write E8 for the split simple algebraic group with Killing-Cartan type E8. The Galois cohomology set H (k, E8) classifies simple algebraic groups of type E8 over k. One of the goals of the theory of algebraic groups over arbitrary fields is to understand the groups of type E8, equivalently, understand the set H(k, E8). The main to...
Recombinant matrices have enabled feeder cell-free maintenance cultures of human pluripotent stem cells (hPSCs), with laminin 511-E8 fragment (LM511-E8) being widely used. However, we herein report that hPSCs maintained on LM511-E8 resist differentiating to multipotent hematopoietic progenitor (HPCs), unlike LM421-E8 or LM121-E8. The latter two LM-E8s bound weakly compared and activated the can...
Milk fat globule-epidermal growth factor 8 (MFG-E8) is an anti-inflammatory glycoprotein that mediates the clearance of apoptotic cells and is implicated in the pathogenesis of autoimmune and inflammatory diseases. Because MFG-E8 also controls bone metabolism, we investigated its role in rheumatoid arthritis (RA), focusing on inflammation and joint destruction. The regulation of MFG-E8 by infla...
BACKGROUND The glycoprotein MFG-E8 mediates phagocytic clearance of apoptotic cells and influences the pathogenesis and progression of inflammatory diseases. MFG-E8 was shown to attenuate the progression of inflammation and to improve survival in septic rats. Accumulating evidence suggests an immunomodulatory link between MFG-E8 and the pro-inflammatory chemokine fractalkine, which may determin...
Infections with high-risk human papillomaviruses (HR-HPV) such as HPV16 and 31 can lead to ano-genital and oropharyngeal cancers and HPV types from the beta genus have been implicated in the development of non-melanoma skin cancer. HPV replicate as nuclear extrachromosomal plasmids at low copy numbers in undifferentiated cells. HPV16 and 31 mutants have indicated that these viruses express an E...
Milk fat globule-epidermal growth factor factor 8 (MFG-E8) regulates innate immune function by modulating cellular signaling, which is less understood. Herein, we aimed to investigate the direct anti-inflammatory role of MFG-E8 in macrophages by pre-treatment with recombinant murine MFG-E8 (rmMFG-E8) followed by stimulation with LPS in RAW264.7 cells and in peritoneal macrophages, isolated from...
بیان موقت ژنهای بیگانه در بافتهای گیاهی برای آنالیز عملکرد ژن در زمان کوتاه روش کارآمدی میباشد. این روش سریع، انعطاف پذیر، ساده و در بافتهای تمایز یافته قابل اجرا است. پیشبر 2a11 از پیشبرهای ویژه بافت میوه گیاه گوجهفرنگی است که باعث بیان بالای ژن 2a11 در میوه میشود. هدف از این تحقیق همسانهسازی پیشبر 2a11 و بررسی بیان آن است. پس از استخراج dna ژنومی از گیاه گوجهفرنگی، پیشبر 2a11 با استفا...
