Described herein is the design and construction of a class of lipoprotein targeting protease inhibitors. Small peptides with protease inhibitor activity are conjugated to hydrophobic, lipoprotein targeting molecules using, for instance, amine reactive chemistry. Methods of use of the resultant lipoprotein targeting protease inhibitor (antiprotease) molecules are also described. Also described is the production and use of protease inhibitor enriched HDL particles, as well as A1AT-peptide-enriched HDL particles, and their use in various therapeutic contexts.

The present invention generally relates to compositions and methods for treatment of subjects having or at risk of arteriosclerosis, hypertension, sickle-cell anemia, or other conditions. In some cases, the composition may include nitric oxide, peptides, or both. The nitric oxide and/or peptide may be present within a first phase comprising a lecithin, such as phosphatidylcholine. In certain embodiments, the lecithin is present in liposomes, micelles, or other vesicles containing nitric oxide and/or peptide. The composition can take the form of a gel, a cream, a lotion, an ointment, a solution, a solid “stick,” etc., that can be rubbed or sprayed onto the skin. Other aspects of the present invention are generally directed to methods of making or using such compositions, methods of promoting such compositions, kits including such compositions, or the like.

A method of modulating growth factor responses of cells expressing C3a receptor (C3aR) and C5a receptor (C5aR) and at least one growth factor receptor includes administering to the cells at least one agent that modulates C3aR and/or C5aR signaling of the cells.
