Research Abstract	項目別にみた本年度の実績概要を記す。(1)脊椎動物、とくに両生類、魚類で新しいMHC遺伝子のクローニングや塩基配列の決定ができた他、MHC領域の遺伝子構成や遺伝子発現に新しい知見を得た。両生類では倍数性が普遍的な現象としてあるが、重複したMHCは部分的に欠失しやすいことが明らかになった。そのため、MHCの遺伝子群は通常とは異なり、複数の染色体に分散している。下等脊椎動物のMHCの分子構造は、高等脊椎動物のそれと類似している知見を得た他に、HSP70分子から進化してきた可能性が指摘された(笠原、橋本、堀)。(2)マウス特有の非古典的MHC分子TLは、器官特異的発現をする。これまでTLは機能をもたないといわれてきたが、TL特異的に誘導されるCD8^+T細胞が存在すること、またTLは限られた抗原だけを提示する知見を得た。これらは、TL様分子がマウス以外にも存在する可能性が高いことを示す。TLの腸内での高い発現は、免疫系が働くのに最も効率がよい場所がどこであるかを示唆している(小幡、森脇、高畑)。(3)ヒトHLA領域の解析が進み、新しい遺伝子座や新しいHLA対立遺伝子の発見があった。これと共に大切な課題は、HLA対立遺伝子やハプロタイプと病気との相関であり、自己免疫疾患に関する基礎的な知見を得た。このような知見は、近い将来新しい免疫療法の開発に役立つものと期待できる。(笹月、猪子、池村、堀)。(4)MHC拘束を受けるT細胞レパートリーの大きさと1個体がもつMHC分子の抗原レパートリーの大きさは、微妙なバランスの上で決まっている。このバランスが破れると自己免疫不全に陥る。これは、MHCがなぜ限られた数の遺伝子座だけで異常に多型的であるかという問題と関係している。この問題を胸線内クローン選択と個体選択の観点から理論的に説明した。対立遺伝子によるMHC拘束が強い程、多型的MHC遺伝子座の数は少なくなる。また異なる遺伝子座のMHC分子による拘束のため、多数の機能的MHC遺伝子座をもつようには進化できなかったと結論された(高畑)。
