Outline of Annual Research Achievements |
本課題では、アレルギー炎症の病態において、炎症メディエーターとしてのペリオスチンが産生され標的細胞にシグナルを誘導する過程を解明することを目的とするし、下記の実験を行い結果を得た。 1.インテグリンαVβ3を強制発現させたSW480細胞を、ペリオスチンを固相化したプレートに播種し、接着した細胞数を定量するシステムを用い、ペリオスチンにインテグリンαVβ3強制発現SW480細胞の接着が有意に増強することを確認した。さらに、このシステムを用いて、リコンビナントペリオスチンタンパク質を抗原とするモノクローナル抗体をスクリーニングし、インテグリンαVβ3強制発現SW480細胞のペリオスチンへの接着を阻害する抗体を作製した。 2. この接着阻害抗体が、接着だけでなく、ペリオスチンによるシグナル伝達を阻害するかどうかを、前年度に構築したNF-κBレポーター遺伝子を導入したNIH/3T3細胞のシステムを用いて、ペリオスチンで誘導されるNF-κBシグナルの当該抗体による阻害の有無を観察することで確認しているところである。 3. 既に樹立している別の抗ペリオスチン抗体を用いて、血漿中からペリオスチンを免疫沈降した。免疫沈降物をSDS-PAGEにかけ、タンパク染色を行ったところ、共沈してくる他の分子のバンドが認められた。これらのバンドを切り出し、含まれる分子を質量分析で同定したところ、複数の分子が同定され、ペリオスチンと結合している可能性が示唆された。これらの分子とペリオスチンとの結合の再現性を、in vitroで確認中である。
