Outline of Research at the Start

本研究は、物理化学ストレスが誘発する治療用モノクローナル抗体の凝集化のメカニズム解明と予測理論構築を目的とし、(A)酸ストレスが誘発する劣化抗体の局所的構造変化の部位の特定、(B)酸ストレスが誘発する劣化抗体のドメインの空間的変位の定量、(C)劣化抗体が形成するマイクロメータ・スケールの凝集体のフラクタル性の判定、(D)異なる物理化学ストレス・異なる可変領域アミノ酸配列の依存性の評価、の4項目を実施する。

Outline of Final Research Achievements

The purpose of this study was to elucidate the mechanism of physicochemical stress-induced aggregation of therapeutic antibodies and to develop a theory to predict aggregation. As a result, we succeeded in identifying the site of local structural change of degraded antibodies induced by acid stress, and revealed that the exposure of the hydrophobic core associated with a slight conformational change in the C-terminus is a common sign of structurally degraded antibodies. The spatial displacement of the domains of degraded antibodies was also quantified, and it was found that at pH 2, the homodimer of the CH3 domain dissociates into single monomers and the native-like quaternary structure is completely disrupted. Furthermore, we performed non-dehydrated and unstained measurements of micrometer-scale aggregates composed of degraded antibodies and confirmed they possess the same fractal dimension as nanometer-scale aggregates.

Academic Significance and Societal Importance of the Research Achievements

本研究で蓄積された治療用抗体の凝集化メカニズムに関する知見は、凝集化予測技術や防止技術の基盤となる。バイオ医薬品の製造管理におけるknowledge-basedからscience-basedへの展開を加速し、治療用抗体の有効性と安全性に関するリスク管理の高度化に寄与することが期待される。また、得られた知見以外にも、本研究で採用した多角的アプローチは、動的な生体高分子の構造状態解析、液中試料の無乾燥・無染色高解像度計測、マルチスケールコロイド科学現象の解明など、関連分野への学術的波及が期待される。
