abstract: In the Technical Comment "Trans-activator gene of HTLV-II: Interpretation" by W. C. Greene et al. (27 Feb., p. 1073), the third-from-the-last sentence should have read, "In addition, using Jurkat or other T-cell lines, Inoue and colleagues (2) and Maruyama et al. (3) have described activation of both the IL-2 receptor and IL-2 genes by the tat-I gene isolated from HTLV-I, which shares similar structural and functional properties with the tat-II gene." Reference 3 should have been to M. Maruyama et al., cell 48,343(1987).
