Zusammenfassung:To provide anti-complement component antibodies, such as anti-C1s antibodies and anti-C1r antibodies, and to provide methods of use thereof.SOLUTION: Provided are an anti-C1s antibody and an anti-C1r antibody; a pharmaceutical formulation comprising the antibody; and a method for treating an individual with a complement-mediated disease or disorder comprising a step of administering the antibody to the individual. The binding specificity and C1q dissociation promotion function of the anti-C1s antibody and the anti-C1r antibody have been evaluated. Time-dependent complement neutralization function and binding to native and truncated C1s or C1r proteins have also been demonstrated for the antibody.SELECTED DRAWING: None 【課題】抗補体成分抗体、例えば、抗C1s抗体および抗C1r抗体、ならびにそれらの使用方法を提供する。【解決手段】抗C1s抗体および抗C1r抗体を提供し、該抗体を含む薬学的製剤、および該抗体を個体に投与する工程を含む補体介在性の疾患または障害を有する個体を治療する方法を提供する。該抗C1s抗体および抗C1r抗体の結合特異性およびC1q解離促進機能が評価されている。該抗体に関して、時間依存的補体中和機能ならびに天然型および切断型のC1sまたはC1rタンパク質への結合性も示されている。【選択図】なし
