Abstract: The present invention relates to novel vaccine therapies, and prophylactic treatments of atherosclerotic diseases. Accordingly there is provided, immunogens comprising specific fragments or derivatives of Apolipoprotein C-III (ApoCIII). The vaccines of the present invention, comprising said immunogens, are potent in the prevention, or reduction, of atherosclerotic plaque formation over prolonged periods of time, thereby reducing the potential of atheroslerosis leading to coronary or cerebrovascular disease. Also provided are methods of treating or preventing atherosclerosis by active vaccination, or passive vaccination through administration to a patient of an antibody that is capable of binding to the specific fragments of ApoCIII. Specific monoclonal antibodies and their use in therapy of atherosclerosis is provided. There is further provided the use of the immunogens of the present invention in medicine, and methods of their production.

Abstract: The present invention relates to novel vaccine therapies, and prophylactic treatments of atherosclerotic diseases. Accordingly there is provided, immunogens comprising apolipoproteins, or fragments or derivatives thereof, which in their native form the whole apolipoprotein has at least one of the following activities: (a) the inhibition of the binding of Apolipoprotein B to its receptor, and, or, (b) the inhibition of lipoprotein lipase. A preferred example of one such apolipoprotein is Apolipoprotein C-III (ApoCIII). The vaccines of the present invention, comprising said immunogens, are potent in the prevention, or reduction, of atherosclerotic plaque formation over prolonged periods of time, thereby reducing the potential of atheroslerosis leading to coronary or cerebrovascular disease.

Abstract: The present invention relates to variants of the human apolipoproteine A-I comprising a cystein in position 151, the corresponding nucleic acids and the vectors containing them. It also relates to pharmaceutical compositions comprising said elements and their utilization, particularly in genic therapy.

Abstract: Method of preparing a lipoprotein modified by incorporation of at least one lipophilic active substance other than a triglyceride, characterized by incorporation of said active substance into an emulsion of a lipid phase in a continuous aqueous phase, by adding to the emulsion, with stirring, an original lipoprotein and at least one lipid transfer protein, allowing the mixture to incubate, and, using known methods, isolating the lipoprotein into which the active substance is incorporated; a lipoprotein thus obtained, and pharmaceutical or cosmetic composition containing such a modified lipoprotein.
