We have cloned two genes for cell surface molecules, capable of delivering the intracellular signals, which are modulated for their expression by Tax. One is the gamma chain of the interleukin-2 (IL-2) receptor which is suggested to be critical for IL-2-dependent growth of human T-cell leukemia virus type I (HTLV-I) infected cells. The gamma chain is upregulated by Tax, like the IL-2 receptor alpha chain. This upregulation may compensate the gamma chain downregulation after IL-2 binding, presumably resulting in more frequent growth of HTLV-I infected T cells. The other is gp34 that was initially identified as a molecule specifically expressed on HTLV-I-infected T cells. gp34 has been demonstrated to bind OX40 which belongs to the tumor necrosis factor (TNF) receptor family. We found that HTLV-I Tax induces expression of gp34 and OX40, and that normal T cell transiently express both gp34 and OX40 upon antigenic stimulation. Collectively, it may be possible that HTLV-I-infected T cells are in a predisposition to growth due to modulated expression by HTLV-I Tax of gp34/OX40 and the gamma chain.
