| Popis: | The regulation of murine T cell proliferation by IL-7 was investigated. Highly purified resting splenic T cells were induced to proliferate in a short term assay by IL-7 in the presence of the comitogen, Con A. The proliferation of these resting T cells showed both IL-2-dependent and -independent components as determined by the susceptibility of the response to the blocking effects of anti-IL-2 mAb. Furthermore, IL-7 was found to augment the Con A-induced production of IL-2 and expression of IL-2R by resting splenic T cells. In contrast, Con A blasts and long term, Ag-dependent cloned T cells proliferated in response to IL-7 independently of any involvement of IL-2. Finally, differences were observed between IL-7 and IL-6 with regard to the regulation of T cell growth and activation. As with IL-7, IL-6 stimulated resting splenic T cells to proliferate in the presence of comitogen. However, in contrast to IL-7, IL-6 failed to stimulate the proliferation of Con A blasts or T cell clones and did not augment the Con A-induced expression of IL-2R on resting T cells. |
