A mouse model of humanized liver shows a human-like lipid profile, but does not form atherosclerotic plaque after western type diet.

Mouse models are a crucial and often used tool to provide insight into the underlying mechanisms of human atherosclerosis. However, mice profoundly differ from humans in lipoprotein synthesis and metabolism, key factors in atherosclerotic plaque formation. Mouse models often require genetic and dietary modifications to mimic human pathophysiology, shifting from a high-density lipoprotein to an low-density lipoprotein dominant lipoprotein profile.
