Outline of Research at the Start

本研究 は、「臓器移植(肝、肺、腎、膵)、造血幹細胞移植において、X、Y の免疫原性を実証す るとともに HLA エピトープ解析に基づいた移植後免疫反応に関わる新規バイオマーカー開 発」を目的とした。具体的には後方視的にエピトープ解析と臨床情報から臓器横断的に 免疫原性の高いエピトープ候補を抽出し、前方視的に X、Y を含む1で抽出されたエピ トープの免疫原性をリンパ球混合試験と臨床転帰から実証すると共に、マスサイトメトリ ーを用いた次世代型解析により移植後免疫反応に関わる新規バイオマーカーを探索する。

Outline of Final Research Achievements

The suppression of antibody-mediated rejection following organ transplantation remains a significant challenge. The primary cause is the development of donor-specific antibodies (DSAs), which arise from Human Leukocyte Antigen (HLA) mismatches between donors and recipients. We focused on the epitope mismatches on HLA molecules, particularly eplets, in liver, lung, and kidney transplant patients. We developed a high-precision cross-organ DSA development prediction algorithm. We identified specific eplets that could serve as therapeutic targets by elucidating the hierarchy of DSA development risk associated with individual mismatched eplets. Furthermore, we developed an application utilizing this algorithm for clinical use.

Academic Significance and Societal Importance of the Research Achievements

我々の導出したアルゴリズムにより、簡便に臓器移植後の高ドナー抗体の出現や拒絶反応のリスクを算出可能なアプリケーションを開発した。これを臨床応用することにより、臓器移植後の至適な免疫抑制剤の投与量の設定を目指すことができる。さらに研究を進めることにより免疫原性の高いepletをターゲットとした抗体によるドナー特異的な免疫抑制療法を開発する学術的な意義を有している。最終的には、臓器移植患者における移植後の新規個別化免疫抑制戦略を構築することを社会的意義がある。
