Key result
LpL deficiency worsens atherosclerotic lesions in mice, indicating TRLs contribute to atherosclerosis.
Why the study?
Higher remnant levels have been implicated in the link between TRLs and CVD, leading researchers to hypothesize that nascent, non-remnant lipoproteins are also atherogenic.
Does induced whole-body lipoprotein lipase deficiency increase atherosclerosis in LDLR-deficient mice on a Western diet?

No immediate clinical implications for lipid management; leaves open whether intact TRLs promote human atherosclerosis beyond remnants.
Does induced whole-body lipoprotein lipase deficiency increase atherosclerosis in LDLR-deficient mice on a Western diet?
Intact, non-remnant triglyceride-rich lipoproteins contribute directly to atherosclerosis and vascular inflammation, challenging the widely accepted view that only remnant lipoproteins are atherogenic.
Cabodevilla et al. (2026) studied this question. Mice with lipoprotein lipase deficiency showed more severe atherosclerotic lesions after 12 weeks on a Western-type diet compared to controls, indicating TRLs contribute to atherosclerosis.
