Keratinocyte growth factor protects against Pseudomonas aeruginosa-induced lung injury.
We have previously reported that keratinocyte growth factor (KGF) attenuates alpha-naphthylthiourea-induced lung injury by upregulating alveolar fluid transport. The objective of this study was to determine the effect of KGF pretreatment in Pseudomonas aeruginosa pneumonia. A 5% bovine albumin solution with 1 microCi of (125)I-labeled human albumin was instilled into the air spaces 4 or 24 h af...
متن کاملIonic signalling by growth factor receptors.
The proliferation of cells in vivo and in culture is regulated by polypeptide growth factors, such as epidermal growth factor (EGF) and platelet-derived growth factor (PDGF). Growth factors initiate their action by binding to specific cell surface receptors. Receptor occupancy triggers a cascade of physiological changes in the target cell which ultimately lead to DNA synthesis and cell division...
متن کاملRegulation of thymic epithelium by keratinocyte growth factor.
Here we demonstrate that keratinocyte growth factor (KGF) and FGFR2IIIb signaling can affect development and function of thymic epithelium (TE) and that alphabeta-lineage thymocytes contribute to intrathymic levels of KGF. Thymocyte expression of KGF is developmentally regulated, being undetectable in CD3-4-8- thymocytes and expressed at highest levels by mature CD4 or CD8 thymocytes. Exposure ...
متن کاملReceptor-mediated endocytosis of keratinocyte growth factor.
Keratinocyte growth factor (KGF) is a fibroblast growth factor which acts specifically on epithelial cells, regulating their proliferation and differentiation. KGF elicits its activity through binding to and activation of KGF receptor, a splicing transcript variant of fibroblast growth factor receptor 2 (FGFR2). Here we analyzed the pathway of internalization of KGF and its receptor using sever...
متن کاملKeratinocyte growth factor and coeliac disease.
BACKGROUND Coeliac disease is characterised by increased epithelial renewal associated with a mucosal T cell response to gliadin. Keratinocyte growth factor (KGF) is produced by cytokine activated gut stromal cells and may be a link between mucosal T cell activation in untreated coeliac disease and epithelial hyperplasia. AIMS To characterise expression of KGF in coeliac disease. METHODS KG...
