Researchers at University of California San Diego School of Medicine discovered that they can block inflammation in mice with a naturally occurring antibody that binds oxidized phospholipids (OxPL), molecules on cell surfaces that get modified by inflammation. Even while on a high-fat diet, the antibody protected the mice from arterial plaque formation, hardening of the arteries and liver disease, and prolonged their lives.

This study, published June 6 by Nature, marks the first demonstration in a living system that OxPL triggers in...

A biomaterials hack can boost cells’ ability to combat inflammation and potentially treat autoimmune diseases. With a trick of engineering, scientists at the Gladstone Institutes improved a potential weapon against inflammation and autoimmune disorders. Their work could one day benefit patients who suffer from IBD or organ transplant rejection.

Model for the regulation of visceral fat ER stress in obesity. Induction of TRIP-Br2 and GATA3 during obesity via ER stress is critical for the visceral fat proinflammatory responses.

Researchers have long-known that visceral fat (which wraps around the internal organs) is more dangerous than subcutaneous fat (under the skin). But how visceral fat contributes to insulin resistance and inflammation has remained unknown. A study points blame at a regulatory molecule in cells called TRIP-Br2 that is produced in response to overeating’s stress on the machinery cells use to produce proteins.

In previous studies, in obese humans TRIP-Br2 was turned-up in visceral fat but not in subcutaneous fat...

In a new heart failure study, the blood system is being explored for the purpose of improving heart function. The study has revealed the potential of a secondary system that had previously received scant attention.

The researchers analysed the heart lymphatic system in an animal model which was highly impaired following a myocardial infarction. Using a biotherapy based on the injection of innovative microparticles, they succeeded in regenerating lymphatic vessels in a targeted manner. This treatment promotes lymphatic drainage, thus limiting post-infarct oedema and inflammation. Heart function is thereby improved.
