Human T cell subsets differ in their ability to migrate in vitro and to produce T cell migration inhibitory factor.

abstract：:Multiple activation signals (including antigen, co-stimulation, and cytokines) during T-cell priming affect the subsequent generation of memory T cells, whose survival is maintained by IL-7 and IL-15. Since the IL-7 receptor is highly expressed not only on the surface of memory T cells but also on naïve T cells, we pr...
