Abstract
Disclosed herein are compositions and methods for eliciting immune responses against antigens. In particular, the compounds and methods elicit immune responses against foreign antigens that are otherwise recognized by the host as “self” antigens, thus breaking host tolerance to those antigens. Presenting the host immune system with a chimeric antigen comprising an immune response domain and a target binding domain, wherein the target binding domain comprises an antibody fragment, enhances the immune response against the foreign or tolerated antigen. Antigen presenting cells take up, process, and present the chimeric antigen, eliciting both a humoral and cellular immune response against the desired antigen.
