“…For example, serum levels of IFNg, sampled at up to 28 days after engraftment, were found to be lowest in paediatric liver transplant patients who tolerated their graft without episodes of rejection [22]. Additionally, in renal transplant patients, urinary protein levels of the IFNginduced chemokine MIG [monokine induced by IFNg known as chemokine (C-X-C motif) ligand 9 CXCL9] and IFN-inducible protein 10 (IP10, CXCL10) were significantly elevated during episodes of biopsy-proven acute rejection [23].…”
