Abstract: This invention provides a composition comprised of nanoparticles containing a therapeutic or diagnostic agent having a block copolymer linked to at least one anionic group as a surface modifier adsorbed on the surface thereof and a method of making such nanoparticles. The compositions exhibit unexpectedly improved autoclave stability, reduced macrophage uptake, improved toxicological profiles and facilitate particle size reduction such that milling time can be reduced and/or sterile filtration of the nanoparticles can be accomplished.

Abstract: The use of substituted glycosides to enhance the penetration of drugs across mucus covered epithelial tissues of humans and animals is disclosed, including enhanced penetrations of topically applied ophthalmic drugs through the corneal epithelium of said humans and animals.

Abstract: Acetylated low density lipoproteins are combined with active and effective lipophilic peptide or other lipophilic immunomodulators, antigens or vaccines to carry the same to macrophage specific targeted receptor mediated endocytosis sites in a living system for treatment of cancer, infection hyperimmune related diseases or deficiences, or to enhance vaccine induction of immunity. Such receptor mediated endocytosis sites are found on macrophages, monocytes and endothelial cells in organs and tissues of the body.The combination of acetyl-LDL and a lipophilic peptide or related lipophilic immunomodulators, antigens, polynucleotides or vaccines enables delivery of such to be made across vascular barriers by transcytosis. The penetration of endothelial blood-brain, eye or testicular barriers is included in this concept.
