CD26/dipeptidyl peptidase IV: A comparative study of healthy persons and kidney transplant recipients before and early after transplantation

CD26 expression on CD3 + cells was strongly increased in patients with end stage kidney disease compared to HP and remained high early postTx. The differences in sCD26 and DPPIV behavior compared to that of CD26 +/CD3 + postTx may reflect a regulatory response to the new immunological situation and the effects of therapy.
