ABSTRACT

Viruses that cause pathology in humans and animals enter the body at different sites and produce disease by a variety of mechanisms. Such invasions are initially countered by innate defense mechanisms (v.gr. NK cells, interferons and other cytokines), that act within minutes of infection. Only when the innate host defenses are by-passed or evaded is induced the adaptive immune response (v.gr. cytotoxic T cells and antibodies that act in antibody-dependent cell-mediated cytotoxicity), and even then the same effector mechanisms that operate in innate immunity are ultimately harnessed to eliminate the pathogen.
