The two-headed antigen. B-cell co-receptors.
Lymphocytes often recognize antigens using not only their antigen receptors but also 'co-receptors' that bind other molecules associated with the antigen; the co-receptors then modulate the response to antigen. This concept has been used to make chimeric antigens that are extremely potent inducers of antibody responses.
