Isolation of Fibronectin Receptors
1990Fibronectin is an adhesive glycoprotein involved in a variety of cellular functions, including adhesion of cells to extracellular matrices, embryonic cell migration and differentiation, wound healing, and hemostasis (Yamada and Olden, 1978; Hynes, 1985; Ruoslahti and Pierschbacher, 1987; Mosher, 1988).

Experimental Cell Research, 1988
We have used a rat neural cell line, B65, to investigate the relative contributions of gangliosides and glycoprotein receptors in adhesion to fibronectin. Monoclonal antibodies against two neuroectoderm-associated gangliosides, D1.1 and GD3, inhibit the rate of B65 attachment to fibronectin, suggesting that these gangliosides are involved in the ...

Identification of fibronectin as a receptor for bacterial cytoadherence
1994Publisher Summary This chapter discusses the identification of fibronectin as a receptor for bacterial cytoadherence. Studies on the associations between bacterial pathogens and certain host proteins likely resulted from serendipitous observations. Such was the case involving fibronectin and Staphylococcus aureus .

[Fibronectin and fibronectin receptors on the surfaces of polymorphonuclear leukocytes].
Biulleten' eksperimental'noi biologii i meditsiny, 1982Interaction between human neutrophils and fibronectin bound to gelatin-Sepharose granules was studied. It was found that fibronectin following cell-induced dissociation from gelatin-Sepharose caused neutrophil aggregation which was inhibited by EDTA or pretrypsinization of the cells.

Changes in cell surface expression of fibronectin and fibronectin receptor during liver regeneration
Journal of Cell Science, 1992ABSTRACT The surface expression of fibronectin and its major integrin receptor in liver, integrinα5β1 was studied during liver regeneration after partial hepatectomy. Using immunoblotting, plasma membranes isolated from livers at different regeneration stages were found to contain 6- to 8-fold elevated levels of fibronectin, α5 and β1 at

Integrin alpha 3, alpha 4, alpha 5, and alpha v subunits heterodimerize with beta 1 and beta 3 chains to form functional fibronectin (FN) receptors. Two of them, alpha 4 beta 1 and alpha 5 beta 1, recognize FN as the only matrix molecule. Additional binding of laminin, collagen, and entactin is achieved by alpha 3 beta 1 while alpha v beta 1 and alpha ...

Fibronectin receptor structures in the VLA family of heterodimers
Nature, 1987Multiple cell surface proteins of relative molecular mass 115,000-155,000 (Mr 115K-155K) have been implicated as receptors mediating adhesion to extracellular matrix proteins. But the organization and relatedness of these peptides has remained unclear.

Effect of selenite on cell surface fibronectin receptor
Biological Trace Element Research, 1994Incubation of cells with selenite, under conditions in which there is no effect on cell viability, results in a decrease in the rate of their subsequent attachment to extracellular matrix proteins such as fibronectin (1). The attachment was inhibited by a pentapeptide containing the RGD sequence and by antibody against the cellular fibronectin receptor

B Lymphocyte Fibronectin Receptors: Expression and Utilization
Scandinavian Journal of Immunology, 1991Lymphocytes adhere to fibronectin (FN) via multiple receptors of the VLA β1 CD29 integrin) family. The cellular requirement for the variety of FN receptors (FNR) which have been described is unclear, but they may be associated with differential signalling processes, cooperative effects which may stabilize cellular attachment, or cell homing and ...

Evidence for the recycling nature of the fibronectin receptor of macrophages
Journal of Cellular Physiology, 1987AbstractPlasma fibronectin (pFN) has been shown to mediate phagocytosis of several types of artificial particles and tissue debris by macrophages. In the present investigation some of the dynamic aspects of this receptor‐mediated cellular process have been studied.
