ABSTRACT:
A new method is described for eliciting IgG antibody response to proteins or synthetic peptides, particularly those that are weakly immunogenic, 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 mammalian recipient 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.
