A new method is described for eliciting IgG antibody response to proteins or synthetic peptides without the requirement for the use of adjuvants, thereby making it easier and safer to confer protection against pathogenic organisms. The antigen is coupled to a monoclonal antibody, specific for membrane determinants expressed on certain types of mamalian recipients cells, called antigen presenting cells. The monoclonal antibody acts as a "vector" or "delivery vehicle" for targeting foreign antigens onto such recipient cells. This targeting facilitates subsequent antigen recognition by helper T-cells, which are pivotal in helping the induction of antigen-specific IgG responses.
本文介绍了一种新方法,可在不需要使用佐剂的情况下激发对蛋白质或合成肽的 IgG 抗体反应,从而更容易、更安全地提供对病原体的保护。 抗原与一种单克隆抗体结合在一起,该抗体对某些类型的哺乳动物受体细胞(称为抗原提呈细胞)上表达的膜决定簇具有特异性。 单克隆抗体充当 "载体 "或 "传递载体",将外来抗原靶向此类受体细胞。 这种靶向性有利于辅助 T 细胞随后识别抗原,而辅助 T 细胞在帮助诱导抗原特异性 IgG 反应方面起着关键作用。
