High-Fat Diet Exacerbates Early Psoriatic Skin Inflammation Independent of Obesity: Saturated Fatty Acids as Key Players

In obesity, hypertrophic adipocytes secrete high amounts of adipocytokines, resulting in low-grade inflammation amplified by infiltrating proinflammatory macrophages, oxidative stress, hypoxia, and lipolysis. These chronic proinflammatory conditions support the development of type II diabetes and cardiovascular diseases, but the mechanisms of obesity-related exacerbation of inflammatory skin disorders like psoriasis are unclear. In this study,...
