Class and subclass selection in parasite-specific antibody responses

Antibodies are characteristically induced in many parasitic infection processes. The class and subclass of the antibody response is instrumental because each isotype has a distinct biological function. It is thus crucially important for an infected individual to mount the most appropriate secondary antibody response - that is the response that has the best chance of clearing the infection and/or controlling disease. This represents a fundamental of vaccine strategies. Immuno-epidemiological surveys and in vitro models of antibody production have helped to understand some of the goals which should be achieved when designing antiparasitic vaccines.
