Expression of apoA-I(L141R)Pisa or apoA-I(L159R)FIN mutations in mice was associated with increased diet-induced atherosclerosis compared to either WT apoA-I transgenic or apoA-I(-/-) mice.
In conclusion, large HDL-like particles containing apoE and apoA-I(L159R) contribute rather than protect against atherosclerosis, possibly through defective efflux properties and their potential for aggregation at their site of interaction in the aorta.
