Where this comes from

Abstract

Gao et al. report that the observed reduction in adipose lipolysis with age in women could be explained by an upregulation of the catecholamine-degradation pathway in subcutaneous adipocytes. However, in contrast to findings in mice, these pathways are enriched in adipocytes and not in immune cells, suggesting species-specific differences in aging mechanisms.
