Nanomedicine-based strategies for treatment of atherosclerosis

•Nanomedical formulations allow for treatment of atherosclerosis in animal models.•Such formulations can target lipid metabolism, inflammation, or mechanisms of destabilization.•Clinical trials are hampered by possible toxic and immunostimulatory/-suppressive properties.

Atherosclerosis is a chronic inflammatory disease of the arterial wall that arises from an imbalanced lipid metabolism and a maladaptive inflammatory response. Despite intensive research on mechanisms underlying atherosclerotic lesion formation and progression during the past decade, translation of this knowledge into the clinic is scarce. Although developments have primarily been made in the area of antitumor therapy, recent advances have shown the potential of nanomedicine-based treatment strategies for atherosclerosis. Here we describe the features of currently available nanomedical formulations that have been optimized for atherosclerosis treatment, and we further describe how they can be instructed to target inflammatory processes in the arterial wall. Despite their limitations, nanomedical applications might hold promise for personalized medicine, and further efforts are needed to improve atherosclerosis-specific targeting.
