Abstract

Brestoff et al. show that adipose-tissue-resident macrophages acquire mitochondria from neighboring adipocytes in a heparan-sulfate-dependent process that is impaired in obesity. Genetic disruption of mitochondria uptake by macrophages reduces energy expenditure and exacerbates diet-induced obesity in mice, indicating that intercellular mitochondria transfer to macrophages mediates systemic metabolic homeostasis.
