主　　题：BMP4 fat browning adipose tissue macrophages 

摘      要：Thermogenic beige fat improves metabolism and prevents *** evidence shows that the activation of M2 macrophages stimulates beige adipogenesis,whereas the activation of Ml macrophages,which play a major role in inflammation,impedes beige ***,the identification of factors that regulate adipose tissue macrophages(ATMs)will help clarify the mechanism involved in ***,we found that one of the secreted proteins in adipose tissue,namely,BMP4,alters the ATM profile in subcutaneous adipose tissue by activating M2 and inhibiting Ml ***,the BMP4-stimutated p38/MAPK/STAT6/PI3K-AKT signalling pathway is ***,BMP4 improved the potency of M2 macrophages to induce beige fat *** that the overexpression of BMP4 in adipose tissue promotes the beiging of subcutaneous adipose tissue and improves insulin sensitivity,these findings provide evidence that BMP4 acts as an activator of beige fat by targeting immuno-metabolic pathways.
