The activation of cytotoxic T lymphocytes by cross-presented antigen (known as cross-priming) is necessary for immunity against certain viruses, bacteria and most tumours. Here, the underlying cellular and molecular mechanisms of cross-priming are described, providing insight into some central questions on the basic mechanisms of cross-priming, and its physiological and therapeutic importance are discussed.
