PG - 223-9 AB - Antibodies to MICA and MICB antigens were sought in the sera of 139 kidney transplant recipients. MICA*001, *002, *007, *008, and MICB*002 antigens were produced in Escherichia coli and then tested using enzyme-linked immunosorbent assay plates. Among 35 normal sera, 6% had MIC antibodies, and among 14 sera from pregnant women, 21% had MIC antibodies. Among 34 patients with functioning transplants with human leukocyte antigen (HLA) antibodies, 24% had MIC antibodies, and 19% of 32 patients without HLA antibodies had MIC antibodies. Among 46 patients who lost grafts with HLA antibodies, 26% had MIC antibodies, and among 27 failed patients without HLA antibodies, 37% had MIC antibodies. We conclude that antibodies to MIC are produced in the course of immunization by pregnancies and kidney transplants. They also occurred more frequently in rejected patients (30%) than in those with functioning grafts (21%).
