Adipose tissue macrophages: Amicus adipem?

Justin I Odegaard et al. Cell Metab. .

Abstract

Chronic overnutrition drives complex adaptations within both professional metabolic and bystander tissues that, despite intense investigation, are still poorly understood. Xu et al. (2013) now describe the unexpected ability of adipose tissue macrophages to buffer lipids released from obese adipocytes in a manner independent of inflammatory macrophage activation.

Figure 1. Adipose tissue macrophages buffer local lipid levels through a program of lysosomal lipid metabolism
Chronic overnutrition dramatically remodels adipose tissue architecture, driving adipocyte expansion and the infiltration of numerous immune cells, including macrophages. Triglycerides released from over-burdened adipocytes are taken up by tissue resident macrophages that function to buffer fatty acid release into circulation through a lysosome-dependent mechanism of lipid catabolism. ATM: adipose tissue macrophages.
