Recent findings support the importance of the adenosine pathway in human immunology. Tissue specific differences exist with respect to the capacity of mesenchymal stem cells (MSC) to produce immune regulatory ATP metabolites. While some MSC may produce adenosine in a cell-autonomous fashion, other types of MSC require the cooperative activity of T-cells. Stem Cells 2017;35:1647-1648.
