Discovery could lead to further advances against diseases tied to obesity and type II diabetes
Researchers at NYU Langone Medical Center have found that blocking the action of a key signaling molecule in the immune system known as Netrin-1 stalls chronic inflammation and insulin resistance tied to obesity and often derived from fatty diets.
Reporting in this week's issue of Nature Medicine, the NYU Langone team showed in experiments in mice and human tissue that Netrin-1 signaling is propelled by fat tissue growth. The team previously discovered that Netrin-1 was secreted by the immune system clean-up cells, or macrophages, whose buildup leads to inflammation.
