Molecular Link between Obesity and Type 2 Diabetes Reveals Potential Therapy

Inflammatory molecule LTB4 promotes insulin resistance in obese mice and blocking the LTB4 receptor prevents and reverses type 2 diabetes in this model —

Obesity causes inflammation, which can in turn lead to type 2 diabetes. What isn’t well established is how inflammation causes diabetes — or what we can do to stop it. Researchers at University of California, San Diego School of Medicine have discovered that the inflammatory molecule LTB4 promotes insulin resistance, a first step in developing type 2 diabetes. What’s more, the team found that genetically removing the cell receptor that responds to LTB4, or blocking it with a drug, improves insulin sensitivity in obese mice. The study is published Feb. 23 by Nature Medicine. … Read the full story from the UC San Diego Newsroom
