Integrin heterodimers which share a common beta 1 subunit are the major cellular receptors for many extracellular matrix proteins. Here, we show that two inflammatory mediators, interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), can regulate the expression of the alpha 1 beta 1 integrin heterodimer, known to be a laminin and collagen receptor. In human skin fibroblasts ...
Vascular endothelial growth factor (VEGF) is a mediator of airway inflammation and remodelling in asthma. Transforming growth factor (TGF)-beta(1) plays pivotal roles in diverse biological processes, including tissue remodelling and repair in a number of chronic lung diseases. However, there are few studies elucidating the interactions between VEGF and TGF-beta(1) in allergic airway disease. A ...
The multifunctional cytokine, transforming growth factor beta (TGF-beta), was identified by immunocytochemistry in the brain tissues of four patients with acquired immune deficiency syndrome (AIDS), but not in control brain tissue. The TGF-beta staining was localized to cells of monocytic lineage as well as astrocytes, especially in areas of brain pathology. In addition, the brain tissues from ...
Five highly homologous epidermal growth factor receptor ligands were studied by mass spectral analysis, hydrogen/deuterium (H/D) exchange via attenuated total reflectance Fourier transform-infrared spectroscopy, and two-dimensional correlation analysis. These studies were performed to determine the order of events during the exchange process, the extent of H/D exchange, and associated kinetics ...
background: elongation factor-1, a conserved nuclear protein coding gene was used to identify iranian sandfly species. the phlebotomine sandfies are the vectors of the parasitic protozoan leishmania, the causative agents of leishmaniasis, in iran. methods: seven sets of primers were tried. pcr amplification of elongation factor-1 was successfully achieved for all 14 species of iranian sandfli...
Transforming growth factor-beta 1 (TGF-beta 1) has been shown to up-regulate the synthesis of nerve growth factor (NGF) in cultured rat astrocytes and in neonatal brain in vivo (Lindholm, D., B. Hengerer, F. Zafra, and H. Thoenen. 1990. NeuroReport. 1:9-12). Here we show that mRNA encoding TGF-beta 1 increased in rat cerebral cortex after a penetrating brain injury. The level of NGF mRNA is als...
