Memories of virus-specific CD8 ⁺ T cells

This brief review focuses on the way that our understanding of virus-specific CD8 ⁺ T-cell-mediated immunity evolved, giving particular attention to the early impact of the program at the Australian National University. The story developed through a sequence of distinct eras, each of which can be defined in the context of the technologies available at that time. The progress has been enormous, but there is a great deal still to be learned. A particular challenge is to use what we know for human benefit.
