摘要:
Atherosclerosis commences with the binding of Low Density Lipoproteins (LDL) to modified proteoglycans. Modifications to proteoglycans which make the environment “stickier” for LDL arise from the actions of growth factors in the vessel wall. The signaling pathways therefore represent therapeutic targets for the prevention of atherosclerosis. We discovered that the protein tyrosine kinase (PTK) inhibitor, imatinib , inhibits proteoglycan synthesis and modifies the structure in a manner that reduces binding of proteoglycans to LDL and reduces the deposition of lipid in the vessel wall of high fat fed atherosclerosis-prone mice. Imatinib inhibits multiple PTK including the Platelet-derived growth factor (PDGF) receptor. The PTKs which are inhibited by imatinib represent targets for the prevention of atherosclerosis.
