Abstract

Objective

Lymphatic vessels collect extravasated fluid and proteins from tissues to blood circulation as well as play an essential role in lipid metabolism by taking up intestinal chylomicrons. Previous studies have shown that impairment of lymphatic vessel function causes lymphedema and fat accumulation, but clear connections between arterial pathologies and lymphatic vessels have not been described.

Approach and Results

Two transgenic mouse strains with lymphatic insufficiency (sVEGFR3 and Chy) were crossed with atherosclerotic mice (LDLR−/−/ApoB100/100) to study the effects of insufficient lymphatic vessel transport on lipoprotein metabolism and atherosclerosis. Both sVEGFR3 × LDLR−/−/ApoB100/100 mice and Chy × LDLR−/−/ApoB100/100 mice had higher plasma cholesterol levels compared to LDLR−/−/ApoB100/100 control mice during both normal chow diet (16.3 mmol/l and 13.7 mmol/l vs. 8.2 mmol/l, respectively) and Western-type high fat diet (e.g. after 2 weeks of fat diet 45.9 mmol/l and 42.6 mmol/l vs. 30.2 mmol/l, respectively). Cholesterol and triglyceride levels in very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL) fractions were increased. Atherosclerotic lesions in young and intermediate cohorts of sVEGFR3 × LDLR−/−/ApoB100/100 mice progressed faster than in control mice (e.g. intermediate cohort mice at 6 weeks 18.3% vs. 7.7% of the whole aorta, respectively). In addition, lesions in sVEGFR3 × LDLR−/−/ApoB100/100 mice and Chy × LDLR−/−/ApoB100/100 mice had much less lymphatic vessels than lesions in control mice (0.33% and 1.07% vs. 7.45% of podoplanin positive vessels, respectively).

Conclusions

We show a novel finding linking impaired lymphatic vessels to lipoprotein metabolism, increased plasma cholesterol levels and enhanced atherogenesis.
