Study reveals novel mechanism that triggers a cell-mediated immune response

Viruses and other disease-causing microbes influence the type of immune response their hosts will develop against them. In some cases, the predominant response involves antibodies, proteins made by the immune system that specifically recognize parts of the invading microbe and mediate its destruction.
