Research Abstract |
まず、濾胞性リンパ腫における高悪性度化について、濾胞樹状細胞に着目して検索を行った。節性の濾胞性リンパ腫では約90%が濾胞樹状細胞のmeshworkが存在するが、約10%の症例がmeshworkを欠如するパターンをとっていた。これらは臨床病理学的に限局期症例が多かった(Pathol Int 2011)。また、同様のmeshworkが欠如するのを特徴とする十二指腸濾胞性リンパ腫では、非常にindolentな経過をたどるが、この原因の一つとして、節性のものとは異なり、AIDの欠如とBACH2の発現があり、memoryB細胞への分化が見られることを証明した(Mod Pathol 2013)。一方で節性の濾胞性リンパ腫には約3-4割で高悪性度化がみられるが、これらのmemoryB細胞の特徴を有さず、細胞学的な起源に特徴があることが考えられた。次に、網羅的な発現解析を行い、節性濾胞性リンパ腫、十二指腸濾胞性リンパ腫、MALTリンパ腫について解析を行った。十二指腸濾胞性リンパ腫はMALTリンパ腫と分子生物学的に近い関係にあり、節性の濾胞性リンパ腫とは一線を画することが判明した。また、十二指腸濾胞性リンパ腫、MALTリンパ腫に医はCCL20, MAdCAM-1の発現が腫瘍形成に重要な役割を果たしていることをつきとめた(Cancer Sci 2014)。さらに、節性の濾胞性リンパ腫について新たな腫瘍化にかかわる遺伝子を抽出し、これらについての高悪性度化にかかわる機能解析を行っている。
