Increased expression of Ectodysplasin A2 Receptor EDA2R is the most remarkable and ubiquitous aging-related transcriptional hallmark (Human Myoblasts)

We report that increased mRNA-expression of Ectodysplasin-A2-Receptor (EDA2R) is the most remarkable aging-associated transcriptional perturbation in humans and that its induction is confirmed in murine-models of Hutchinson-Gilford progeria syndrome and in other species. Up-regulation of EDA2R occurs in all solid-tissues and is complemented by the progressive transcriptional increase of its ligand in bloodstream. Strengthening of EDA2R/EDA-A2 signaling may exacerbate inflammation in ageing individuals which might be prevented by EDA2R/EDA-A2 blockade.
