General Comments
The EPO/EPOR sytem is responsible for erythropoiesis and has an endogenous tissue protective role. The classical hematopoietic EPO receptor is a homodimer of two EPOR subunits. A non-hematopoietic EPOR-containing receptor, called the innate repair receptor (IRR) or tissue-protective receptor exists, and structurally this is a heterodimer composed of the EPOR and the cytokine receptor β common receptor subunit (CD131) [1].
