The list of diseases and conditions complicated by obesity is a long one; it includes heart disease, cancer, diabetes and impaired wound healing, as well as skin infections. It is not always clear, however, in what way this complication is caused. New research from the School of Pharmaceutical Science at Xiamen University and the Gallo Lab at UC San Diego School of Medicine, published last month in Science Translational Medicine, has uncovered the mechanisms that link obesity and skin infections, and identified a treatment option that will soon be tested in a Phase 2 clinical trial.
