Outline of Final Research Achievements |
To identify the association between KIR gene polymorphisms and susceptibility to EBV-LPD (EB virus-associated lymphoproliferative disorder), we determined EBV copy numbers in the whole blood of patients suspected of having EBV-LPD using quantitative real-time PCR, and determined the KIR gene profile of these patients as well as those who develop non-EBV associated lymphoma and healthy individuals using PCR with specific primers. In patients with EBV-LPD, the frequencies of KIR2DS1, 2DS5 and 2DL5 were significantly lower than those in healthy individuals and non-EBV associated lymphoma. The result suggests that the KIR gene repertoire may be associated with susceptibility to EBV-LPD.

Academic Significance and Societal Importance of the Research Achievements |
KIR 遺伝子プロフィルがEBV-LPDの発症に影響する可能性が示唆されたことで、免疫抑制療法中の患者において、よりEBV-LPDを発症しやすい患者群の特定につながる可能性がある。また、EBV再活性を来した患者において、治療方針の改善につながる可能性がある。
