How 'memory' T cells curb the spread of viruses throughout the body

...pread quicker. Sigal’s work shows the CD8 T cells can protect from viral disease without the need to migrate from the lymph nodes to the site of viral entry. “It was very difficult to imagine how the memory T cells could win this race,” said Sigal, the lead author of the study. The Fox Chase expe...
