Distress signal from fat cells prompts heart to shore up defenses against consequences of obesity
A stress signal received by the heart from fat could help protect against cardiac damage induced by obesity, a new study led by UT Southwestern researchers suggests. The finding, published online in Cell Metabolism, could help explain the “obesity paradox,” a phenomenon in which obese individuals have better short- and medium-term cardiovascular disease prognoses compared […]
Cytokine increases production of ‘beige fat’ to burn more cellular energy: New insights point toward a potential obesity treatment
An immune signal promotes the production of energy-burning “beige fat,” according to a new study publishing Aug. 5 in the open-access journal PLOS Biology by Zhonghan Yang of Sun Yat-Sen University, Guangzhou, China, and colleagues. The finding may lead to new ways to reduce obesity and treat metabolic disorders. The beige color in beige fat […]
