Upon encountering the relevant pathogen, memory T cells are thought to initiate cell division much more rapidly than their naive counterparts, and this is thought to confer a significant biological advantage upon an immune host." "Here, we use traceable TCR-transgenic T cells to evaluate this proposed characteristic in CD4(+) and CD8(+) memory T cells. We find that, even in the presence of abundant antigen that was sufficient to induce in vivo IFN gamma production by memory T cells, both memory and naive T cells...
