Comparisons of T lymphocyte subsets and HLA-DR-positive monocyte between the stable KTRs and 2 groups of KTRs according to the sum scores of MI. The frequencies of CD4⁺HLA-DR⁺/CD4⁺ T cells and CD8⁺HLA-DR⁺/CD8⁺ T cells at the time of biopsy were significantly increased in KTRs with MI sum score ≥ 1 (n = 13) in KTRs with an MI sum score = 0 (n = 11; P = 0.018 and P = 0.037, respectively) as well as KTRs in the normal control group (P = 0.015 and P = 0.038, respectively).

HLA-DR = human leukocyte antigen-antigen D related, KTRs = kidney transplant recipients; MI = microcirculation inflammation, DR = antigen D related, MFI = mean fluorescence intensity.
