Levels of anti-inflammatory extracellular adenosine are controlled by the sequential action of the ectonucleotidases CD39 and CD73, whose expression in CD4(+) T cells has been associated with natural regulatory T cells (nTregs). We here show that CD73 expression on activated murine CD4(+) T cells is induced by TGF-β independently of Foxp3 expression, operates at the transcriptional level and translates into gain of functional capacity to generate adenosine. In the presence of AMP, CD73 induce...Expand abstract
