Interestingly, a selective overexpression of DGAT1 in mice macrophages and adipocytes exhibits a higher propensity for obesity, however, up-regulated DGAT1-dependent triacylglycerol storage ameliorates metabolic complications arising from obesity, including inflammatory macrophage activation, macrophage aggregation in white adipose tissue, systemic inflammation, and insulin resistance. Here, DGAT1 is linked to Obesity.
