Popis: The presence of MICA antibodies was examined in eleven patients diagnosed with AHR. MICA typing was performed in both recipients and donors. Sera were collected sequentially: pre-transplant, at the AHR episode and at follow-up. Sera from 30 patients with functioning graft were also analysed. A stable MICA()008 transfected cell line was used as target to identify MICA antibodies. MICA antibodies were not detected pre-transplant nor post-transplant in patients receiving a compatible graft. MICA antibodies were detected post-transplant AHR in patients receiving an incompatible graft. The persistence of MICA antibodies was associated with chronic graft dysfunction in 3 of 4 patients in this series; although it was not always associated with the graft loss in treated AHR. None of the 30 patients in the control group with long-term functioning grafts showed antibodies to MICA()008. This report provides some insights of the relevance of MICA antibodies in AHR.
