[MICA*008/A5.1 allele and HCMV infection in kidney transplanted donees of Hunan Han nationality].

Objective: To investigate the relationship between MICA*008/A5.1 allele and human cytomegalovirus (HCMV) infection in kidney transplanted donees of Hunan Han nationality.
Methods: The MICA*008/A5.1 allele based on 91 kidney transplanted donees and 81 unrelated normal individuals of Han nationality in Hunan Province were analyzed by PCR/SSP assay. At the same time, anti-HCMV antibody IgM was detected in the serum by ELISA method.
Results: The positive rate of MICA*008/A5.1 allele was significantly higher in the control group (56.79%) than that in the kidney transplanted donee group (34.07%) (P <0.05). The infection rate of HCMV in those individuals whose genotype was MICA*008/A5.1 (-) was significantly higher than that in the MICA*008/A5.1(+).
Conclusion: The individual whose genotype is MICA*008/A5.1 (+) is not liable to HCMV infection, but the individual whose genotype is MICA*008/A5.1 (-) is liable to HCMV infection.
