HDL

A new view of a cholesterol carrier

Vanderbilt researchers developed a novel method to measure small RNAs carried by HDL and demonstrated that these molecules circulate in greater concentrations than previously believed and are likely to contribute to communication between immune cells.

The study could suggest ways to promote the transport of phospholipids and cholesterol out of macrophages, immune system cells that play key roles in all stages of atherosclerosis development.

Study suggests new mechanism for lipid transporter

A new model suggests that a protein involved in the generation of high-density lipoprotein (HDL) works differently than previously thought.

Potential protection from atherosclerosis

Vanderbilt researchers have discovered a potential way to reduce atherosclerosis: blocking the modification of an HDL-associated enzyme by reactive molecules called isolevuglandins.

Cholesterol

NIH grant bolsters research on heart disease, cholesterol

Thanks to major funding from the National Institutes of Health (NIH), researchers at Vanderbilt University Medical Center have made major inroads in understanding how high-density lipoprotein (HDL), commonly known as good cholesterol, in some cases may actually contribute to the development of atherosclerosis.

A new contributor to atherosclerosis

Sean Davies and colleagues are exploring lipid aldehydes produced during oxidative stress and their contribution to HDL dysfunction and atherosclerosis.

HDL-cholesterol and breast cancer risk

Genetic analyses suggest that high circulating HDL-cholesterol levels may increase breast cancer risk — a surprising finding since increased HDL-cholesterol is thought to be healthy.
