Stimulation of an immune response with antibodies labeled with the alpha -galactosyl epitope

摘要

Humoral and cellular immune responses against tumor cells and infectious agents are induced in a mammal using an antibody that binds with an epitope of an antigen that is associated with a tumor or an infectious agent, and that contains at least one alpha -galactosyl epitope. Such an antibody is capable of forming a complex with cells that express the target epitope and with antibodies that bind alpha -galactosyl epitopes. Suitable antibodies include molecules that contain at least one engineered glycosylation site in the constant region of the heavy chain.
