What's impressive about their research is that they realized that it would be worth using less aggressive and less-differentiated memory T cells rather than using the tougher, mature, and more-specialized CMV-programmed T cells. They can apparently isolate the memory T cells that "know" about CMV.
Their theory is that the process they successfully used to provide CMV immunity in mice will be applicable to humans because CMV-specific memory T cells in mice and humans are genetically similar. Let's hope so!
