Brief Summary

BACKGROUND: A notorious and dreaded adverse effect of glucocorticoids (GC) is redistribution of muscle and fat mass towards muscle wasting and visceral obesity. Fibroadipogenic progenitors (FAPs) are hypothesized to mediate this process. AIM: Utilizing human data, the investigators study the effects of GC exposure on skeletal muscle structure and function, adipose tissue and skin in healthy older subjects. METHODS: FAPs will be analyzed in biopsies from skeletal muscles, adipose tissue and skin and further characterized using scRNA-sequencing and Fluorescence-Activated Cell Sorting. Body composition including muscle mass (DXA scan), muscle strength, spontaneous physical activity and glucose homeostasis are recorded. PERSPECTIVES: The investigators combine translational research with multidisciplinary and international collaboration to elucidate the pathophysiology of GC excess, which is of significant clinical interest since 3% of the Danish population receive GC treatment.
