Adipocytes are cells that make up adipose tissue, which is also known as body fat. These cells store energy in the form of lipids, and play a key role in regulating metabolism and energy balance. Adipocytes also secrete hormones and cytokines that are important for regulating various physiological processes in the body, such as inflammation, insulin sensitivity, and appetite. Research in this area focuses on understanding the function and regulation of adipocytes, as well as their role in obesity, diabetes, and other metabolic disorders.
