| pubmed-article:14764683 | pubmed:abstractText | Transient TCR stimulation induces multiple rounds of CD8 T cell division without further requirement for Ag. The mechanism driving Ag-independent proliferation, however, remains unclear. In this study, we show that the initial duration of TCR stimulation positively correlates with the number of divisions that CD8 T cells subsequently undergo. We find that increased periods of Ag stimulation result in enhanced CD25 up-regulation and greater IL-2 production by CD8 T cells. Depletion of IL-2 from T cell cultures with specific Abs dramatically impairs programmed proliferation. Consistent with this result, IL-2-deficient T cells undergo markedly attenuated Ag-independent proliferation in vitro. Although IL-2 production by stimulated CD8 T cells appears to be essential for in vitro proliferation, upon transfer into recipient mice, IL-2-deficient CD8 T cells undergo extensive proliferation in vivo after transient stimulation. Furthermore, the extent of in vivo proliferation correlates with the duration of in vitro Ag stimulation. These results indicate that the requirements for autocrine IL-2 production by CD8 T cells differs between in vitro and in vivo conditions and suggests that factors in addition to IL-2 can support Ag-independent CD8 T cell proliferation. | lld:pubmed |
