Identification of fibronectin as a receptor for bacterial cytoadherence

1994
Publisher 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, 1982
Interaction 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, 1992
ABSTRACT 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

FIBRONECTIN AND FIBRONECTIN-RECEPTORS OF THE INTEGRIN TYPE IN NORMAL COLON MUCOSA, ADENOMA AND CARCINOMA

International Journal of Oncology, 1994
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, 1987
Multiple 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, 1994
Incubation 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

Fibronectin Receptor Expression on Thymocytes

1990
Entrance of precursor T cells into the thymus and their subsequent exit into the circulation are prerequisite events for development of mature T-lymphocyte characteristics (1). Thymic epithelial cells may play an integral role in thymocyte differentiation, both through direct contact and by secretion of thymic hormones (2).

B Lymphocyte Fibronectin Receptors: Expression and Utilization

Scandinavian Journal of Immunology, 1991
Lymphocytes 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 ...

Fibronectin and Its Integrin Receptors in Cancer

1999
The adhesive extracellular matrix protein fibronectin and its integrin receptors play important roles at several stages of tumor development. Tumor cells are generally less adhesive than normal cells and deposit less extracellular matrix. The loosened matrix adhesion that results may contribute to the ability of tumor cells to leave their original ...

Evidence for the recycling nature of the fibronectin receptor of macrophages

Journal of Cellular Physiology, 1987
AbstractPlasma 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.
