Adipocyte mitochondria
WebMay 31, 2024 · In contrast white adipocytes have one large lipid droplet and very few mitochondria [ 11, 12 ]. Prior studies have shown that imaging agents able to quantify mitochondrial expression can aid in the detection of new beige fat deposits in WAT after β 3AR agonist stimulation [ 8, 13 ]. WebMay 3, 2024 · Brown adipocytes regulate body temperature by using their plentiful pools of mitochondria to generate heat in a process called thermogenesis. Rosina et al. found that efficient thermogenesis required the breakdown of damaged mitochondria released from brown adipocytes in extracellular vesicles by brown adipose tissue (BAT) macrophages.
