Abstrakt: It is shown that in the absence of antigenic stimulus interleukin-7 (IL-7) is capable of increasing the content of cells expressing the CD25 molecule among both CD4-positive and CD4-negative effector memory T-cells (CD45RA-CD197-), as well as terminally differentiated T cells (CD45RA+CD197-) without causing a significant impact on the status of the activation of naive T cells (CD45RA+CD197+) and central memory T cells (CD45RA-CD197+). IL-7 was also able to enhance T-cell production of IL-2, interferon-γ (IFN-γ) and IL-10, but not IL-4. These data indicate the involvement of IL-7 into a direct upregulation of growth and functional activity of human T cells in the absence of antigenic stimulus and the relative scarcity of costimulatory effects.
