In vitro analyses of paracrine effects of murine classically activated macrophage on beige adipocyte metabolism.

The communication between macrophage and adipocyte plays a critical role in the initiation and development of metabolic inflammation, which is difficult to study in vivo. Here, we provide a step-by-step protocol using differentiated cells to investigate the paracrine effects of classically activated macrophage on beige adipocyte metabolism in vitro. This protocol uses bone-marrow-derived macrophage and SVF-derived UCP1+ beige adipocyte in a culture model to study immune regulation of adipocyte metabolism by western blot analyses. For complete details on the use and execution of this protocol, please refer to Yao et al. (2021).
