Specific antibodies protect us against viral infections – or do they not? Researchers at the German Cancer Research Center (DKFZ) studied the immune response to papillomaviruses in mice and discovered a hitherto unknown mechanism by which the pathogens outwit the immune system: At the beginning of the infection cycle, they produce a longer version of a protein that surrounds the viral genome. The body produces antibodies against this protein, but they are not effective in fighting the pathogen.
