Emulating Early Atherosclerosis in a Vascular Microphysiological System Using Branched Tissue-Engineered Blood Vessels.

Adv Biol (Weinh) 2021 Apr 6;5(4):e2000428. Epub 2021 Mar 6.

Department of Biomedical Engineering, Columbia University, New York, NY, 10027, USA.

Atherosclerosis begins with the accumulation of cholesterol-carrying lipoproteins on blood vessel walls and progresses to endothelial cell dysfunction, monocyte adhesion, and foam cell formation. Endothelialized tissue-engineered blood vessels (TEBVs) have previously been fabricated to recapitulate artery functionalities, including vasoconstriction, vasodilation, and endothelium activation. Here, the initiation of atherosclerosis is emulated by designing branched TEBVs (brTEBVs) of various geometries treated with enzyme-modified low-density-lipoprotein (eLDL) and TNF-α to induce endothelial cell dysfunction and adhesion of perfused human monocytes.

The role of vascular endothelial growth factor in ischemic stroke.

Pharmazie 2021 Apr;76(4):127-131

College of Life Sciences, Zhejiang Chinese Medical University, Hangzhou, Zhejiang, China.

Ischemic stroke is an injury caused by temporary or permanent cerebral vascular occlusion. It has a high incidence, mortality, and disability rate in clinical practice, and thus poses a considerable threat to public health as one of the top three major conditions endangering human health. Vascular endothelial growth factor is a specific mitogen of endothelial cells and a protein factor that is closely related to ischemic stroke. Read More

The benzoate plant metabolite ethyl gallate prevents cellular- and vascular-lipid accumulation in experimental models of atherosclerosis.

Biochem Biophys Res Commun 2021 Apr 8;556:65-71. Epub 2021 Apr 8.

School of Chemistry and Chemical Engineering, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250353, China. Electronic address:

Ethyl gallate (EG) is a well-known constituent of medicinal plants, but its effects on atherosclerosis development are not clear. In the present study, the anti-atherosclerosis effects of EG and the underlying mechanisms were explored using macrophage cultures, zebrafish and apolipoprotein (apo) E deficient mice. Treatment of macrophages with EG (20 μM) enhanced cellular cholesterol efflux to HDL, and reduced net lipid accumulation in response to oxidized LDL. Read More

High-density lipoproteins, reverse cholesterol transport and atherogenesis.

Nat Rev Cardiol 2021 Apr 8. Epub 2021 Apr 8.

Weill Cornell Medicine, New York, NY, USA.

Plasma HDL-cholesterol concentrations correlate negatively with the risk of atherosclerotic cardiovascular disease (ASCVD). According to a widely cited model, HDL elicits its atheroprotective effect through its role in reverse cholesterol transport, which comprises the efflux of cholesterol from macrophages to early forms of HDL, followed by the conversion of free cholesterol (FCh) contained in HDL into cholesteryl esters, which are hepatically extracted from the plasma by HDL receptors and transferred to the bile for intestinal excretion. Given that increasing plasma HDL-cholesterol levels by genetic approaches does not reduce the risk of ASCVD, the focus of research has shifted to HDL function, especially in the context of macrophage cholesterol efflux.

Clinical and subclinical findings in heterozygous carriers: results from a Belgian cohort and clinical practice guidelines.

J Med Genet 2021 Apr 5. Epub 2021 Apr 5.

Center for Medical Genetics, University Hospital Ghent, Ghent, Belgium

Background: Biallelic pathogenic variants in the () gene cause pseudoxanthoma elasticum, a multisystemic ectopic calcification disorder, while heterozygous variants are associated with an increased risk of cardiovascular and cerebrovascular disease. As the prevalence of pathogenic variants in the general population is estimated at ~1%, identifying additional -related (sub)clinical manifestations in heterozygous carriers is of the utmost importance to reduce this burden of disease. Here, we present a large Belgian cohort of heterozygous carriers with comprehensive clinical, biochemical and imaging data. Read More
