Abstract

abstract the present inventors created antigen-binding molecules containing an antigen-binding domain and an fc?-receptor-binding domain, wherein the molecules have human-fcrn-binding activity in an acidic ph range condition, the antigen-binding domain changes the antigen-binding activity of the antigen-binding molecules depending on the ion-concentration condition, and the fc? receptor-binding domain has higher binding activity to the fc? receptor in a neutral ph range condition than an fc region of a native human igg in which the sugar chain bound at position 297 (eu numbering) is a fucose-containing sugar chain. changes from the specification of wo2013/047729 (our ref.: c1-a1110p) to that of wo2013/047752 (our ref.: c1-a1111p). unchanged parts are shown in black. changes in the tables are not shown. this document is provided solely for your reference and convenience. when preparing a translation, please refer to and literally translate the english specification into your language. -------------------------------------------------------------------------- tradução do resumo resumo patente de invenção: "molécula de ligação a antígeno pa-ra promoção de perda de antígenos". a presente invenção refere-se a moléculas de ligação a an-tígeno contendo um domínio de ligação a antígeno e um domínio de ligação a receptor fc?, onde as moléculas têm atividade de ligação a fcrn humano em uma condição de faixa de ph ácido, o domínio de ligação a antígeno muda a atividade de ligação a antígeno das molé-culas de ligação a antígeno dependendo da condição de concentração de íon, e o domínio de ligação a receptor fc? tem atividade de ligação mais alta ao receptor fc? em uma condição de faixa de ph neutro do que uma região fc de uma igg humana nativa onde a cadeia de açúcar ligada na posição 297 (numeração eu) é uma cadeia de açúcar contendo fucose.
