3-Nitrotyrosine inhibits fibroblast-mediated collagen gel contraction and chemotaxis.
Reactive nitrogen species induce tissue inflammation and nitrate tyrosine residues of various kinds of proteins. Recent studies have established that the free amino acid form of 3-nitrotyrosine induces cytotoxity and growth inhibition and alters the cellular function in cultured cells. The aim of this study was to evaluate whether 3-nitrotyrosine could affect tissue remodelling in fibroblasts. ...
متن کاملS100A4 Regulates Macrophage Chemotaxis
S100A4, a member of the S100 family of Ca(2+)-binding proteins, is directly involved in tumor metastasis. In addition to its expression in tumor cells, S100A4 is expressed in normal cells and tissues, including fibroblasts and cells of the immune system. To examine the contribution of S100A4 to normal physiology, we established S100A4-deficient mice by gene targeting. Homozygous S100A4(-/-) mic...
متن کاملProstaglandin E(2) inhibits fibroblast chemotaxis.
Fibroblasts are the major source of extracellular connective tissue matrix, and the recruitment, accumulation, and stimulation of these cells are thought to play important roles in both normal healing and the development of fibrosis. Prostaglandin E(2) (PGE(2)) can inhibit this process by blocking fibroblast proliferation and collagen production. The aim of this study was to investigate the inh...
متن کاملA Role for Cdc42 in Macrophage Chemotaxis
Three members of the Rho family, Cdc42, Rac, and Rho are known to regulate the organization of actin-based cytoskeletal structures. In Bac1.2F5 macrophages, we have shown that Rho regulates cell contraction, whereas Rac and Cdc42 regulate the formation of lamellipodia and filopodia, respectively. We have now tested the roles of Cdc42, Rac, and Rho in colony stimulating factor-1 (CSF-1)-induced ...
متن کاملCellular signaling in macrophage migration and chemotaxis.
Whereas most cells in adult tissues are fixed in place by cell junctions, leukocytes are motile and able to migrate actively through the walls of blood vessels into surrounding tissues. The actin cytoskeleton of these cells plays a central role in locomotion, phagocytosis, and the regulation of cell shape that are crucial elements of neutrophil and monocyte/macrophage function. This review will...
