In the context of the Center for Functional Genomics and Tissue Plasticity (ATLAS), the Mandrup Group investigates the plasticity of adipose tissue in response to obesity and weight loss. We apply single cell technologies combined with other functional genomics approaches to study the transcriptional networks and cellular crosstalk driving cellular plasticity of human adipose tissues; however, we also use models for mechanistic follow-up studies.
Single-nucleus RNA sequencing (snRNA-seq) analyses of mouse and human white adipose tissues by ATLAS and others have demonstrated several distinct subpopulations of the major cell types in human adipose tissues, i.e., adipocytes, fibro-adipo progenitors, and macrophages. Importantly, we and others have shown that the adipocyte and macrophage subpopulations undergo dramatic quantitative and qualitative changes during weight gain, and several lines of evidence indicate that this remodeling has major implications for adipose tissue adaptation as well as obesity pathology. We are investigating how the tissue architecture and intrinsic and extrinsic molecular signals drive cellular fate decisions and tissue plasticity during weight gain and to what extent these signals differ between depots. Furthermore, we investigate to what extent cellular and molecular signatures persist following weight loss.
