The present invention provides Arg-Gly-Asp peptides that can alter the binding of osteoclasts to a matrix such as bone or can selectively alter integrin receptor binding. The invention also provides methods of using the Arg-Gly-Asp peptides to alter .alpha..sub.v .beta..sub.3 integrin receptor-mediated binding of a cell such as an osteoclast, endothelial cell or smooth muscle cell to a matrix. The invention further provides methods for ameliorating the severity of a pathology characterized, in part, by an undesirable level of bone resorption, angiogenesis or restenosis in a subject.

Peptides for altering bone resorption, angiogenesis and restenosis

The present invention provides Arg--Gly--Asp peptides that can alter the binding of osteoclasts to a matrix such as bone or can selectively alter integrin receptor binding. The invention also provides methods of using the Arg--Gly--Asp peptides to alter .alpha..sub.V .beta..sub.3 integrin receptor-mediated binding of a cell such as an osteoclast, endothelial cell or smooth muscle cell to a matrix. The invention further provides methods for ameliorating the severity of a pathology characterized, in part, by an undesirable level of bone resorption, angiogenesis or restenosis in a subject.
