酶、激素或抗体的生物活性只有在识别其特定靶标后才会被诱导。这种选择性活性是在自然界中用具有至少两种不同功能(识别和生物活性)的分子获得的,通常由同一分子的不同结构域执行。抗体活性的特异性是通过顺序参与获得的,首先是结合单元,然后激活效应器功能,即补体结合抗体仅在首先与其特异性抗原结合时激活补体系统并破坏靶细胞。将抗体特异性细胞裂解应用于肿瘤被动免疫治疗的想法多年来一直非常有吸引力。然而,抗体破坏动物或人类肿瘤的能力一直是有限的,并且经常观察到特异性抗体可以促进肿瘤生长(增强现象)。因此,人们进行了一系列尝试,通过将任一抗癌剂附着到这些抗体上来使抗体的效应器功能更有效,这是Mathe等人首先描述的一个尝试性步骤。 (1958),或毒素,由 Moolten & Cooperband (1970) 发起。然而,只有当它对靶组织具有特异性时,更高的效力才会有利于肿瘤治疗,从某种意义上说,效应器功能
Biological activities of enzymes, hormones or antibodies are induced only after recognition of their specific targets. This selective activity is obtained in Nature with molecules which possess at least two different functions, recognition and biological activity, in general performed by different domains of the same molecule. Specificity of antibody activity is obtained by the sequential involvement, first of the binding unit, which then activates the effector function, i.e. complement-binding antibodies only activate the complement system and destroy target cells if they are first bound to their specific antigen. The idea of applying specific cell lysis by antibodies to passive immunotherapy of tumors has been very attractive for many years. However, the capacity of antibodies to destroy tumors in animals or man has always been limited, and it has often been observed that specific antibodies can enhance tumor growth (enhancement phenomenon). As a result, a series of attempts have been made to render the effector function of antibodies more potent by attaching either anticancer agents to these antibodies, a tentative step first described by Mathe et al. (1958), or toxins, as initiated by Moolten & Cooperband (1970). Higher potency, however, will only be beneficial for tumor therapy if it is specific for the target tissue, in the sense that the effector function
