This invention provides purified antigens which are indicative of the presence of atherosclerotic plaque. Different concentrations of these antigens have been found to coincide with the progression of atherosclerosis. The subject invention also provides different hybridoma cell lines which produce monoclonal antibodies directed to antigens associated with atherosclerosis and a hybridoma cell line which produces monoclonal antibodies directed to antigen associated with normal artery and not with plaque. The atherosclerotic plaque antigen, and monoclonal antibodies made thereto, are used in various methods for detecting in a biological sample an antigen present in, and indicative of the presence of, atherosclerotic plaque. The monoclonal antibodies are also used in methods of imaging atherosclerotic plaque, and treating atherosclerosis. The methods of treating atherosclerosis include a method of digesting atherosclerotic plaque with enzymes, and a method of ablating atherosclerotic plaque using radiation. The subject invention also provides a method of treating atherosclerotic plaque by directly delivering a drug to the plaque. The subject invention further provides a method for treating atherosclerosis by blocking the synthesis of atherosclerotic plaque or by blocking binding of antibodies to the antigen. |
