Outline of Research at the Start

本研究では難病指定されている自己免疫性肝炎と原発性胆汁性胆管炎についてHLAクラスⅠ抗原とナチュラルキラー(NK)細胞の受容体であるKiller cell Immunoglobulin-like Receptor遺伝子サブタイプを次世代シークエンサーで超高解像度解析を行うことで構造変化・変異を明らかにすることと、NK細胞内のシグナル伝達機構を解析することで、疾患発症・病態進展との関連性を明らかにする。

Outline of Annual Research Achievements

本年度は、HLA-G遺伝子多型(rs1736933 [-486 C > A]、rs1049033 [+2018 C > T]、14 bp Insertion [Ins]/Deletion [Del] [+2961 Del > Ins]、rs1063320 [+3142 C > G])と肝細胞癌(HCC)発症、B型肝炎表面抗原(HBsAg)クリアランスとの関連を検討した。
3つのSNPs(-486 C > A, +2018 C > T, +3142 C > G)の対立遺伝子はTaqMan 5'エキソヌクレアーゼアッセイで行い、14bpのIns/Del多型はGenetic AnalyzerとGeneMapperソフトウェアを用いた断片解析でタイピングした。
日本人HBV陽性者325人、健常人355人、HCV陽性者799人について、それぞれ上記の多型を解析した。結果:14 bp Insertion alleleはHBV患者でControlsより有意に高頻度であったが(27.1% vs 20.6%, OR 1.43, P = 0.005)、HCV患者とControlsの間に差はなかった。同様の結果がrs1063320 G対立遺伝子(38.9% vs.26.3%、OR 1.78、P < 0.001)とrs1736933 T対立遺伝子(32.2% vs. 26.9%、OR 1.29、P = 0.034)でもHBVとControlsの間で認められた。rs1049033 T対立遺伝子は弱いが有意な相関を示した。(Okumura et al. Human Immunology 2023)
現在、PBC患者についての検討を進めており、さらに発癌症例について発癌部と非発癌部、血液を収集し、そのHLA遺伝子とKIR遺伝子についてNGSで解析し、一部の結果が出ている。

Current Status of Research Progress
Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

KIR/HLAと自己免疫性肝炎、B型肝炎、C型肝炎の関連性については報告済みである。
次年度は原発性胆汁性胆管炎におけるKIR/HLAの関連性について検討、解析を行うことである。

Strategy for Future Research Activity

原発性胆汁性胆管炎患者は400名の患者、325名の健常人のデータを合わせて疾患感受性、病態予後との関連性について論文作成を行っているところである。
