Binding agents with differential activity can be provided, whereby certain activities of a first part of the binding agent are reduced or prevented until binding to a target occurs. This is useful if the binding agent is intended to bind both an effector cell and a target to be destroyed, because the effector cell can be protected from significant cell damage that might otherwise occur (e.g. due to premature activation of complement and/or ADCC). Such binding agents are useful in the treatment of cancer, for example.
可以提供具有不同活性的结合剂,从而降低或阻止结合剂第一部分的某些活性,直到与目标物结合。如果结合剂既要与效应细胞结合,又要与待破坏的靶点结合,这就非常有用,因为效应细胞可以得到保护,避免可能发生的重大细胞损伤(例如,由于补体和/或 A
DCC 的过早激活)。这种结合剂可用于治疗癌症等。
