Hieshima, K., D. Nagakubo, T. Nakayama, A.-K. Shirakawa, Z. Jin, and O. Yoshie. 2008. Tax-inducible production of CC chemokine ligand 22 by human T cell leukemia virus type 1 (HTLV-1)-infected T cells promotes preferential transmission of HTLV-1 to CCR4-expressing CD4+ T cells. J. Immunol. 180: 931–939 .

In Materials and Methods, the following primers for Tax mentioned in the first paragraph under the heading Semiquantitative RT-PCR are incorrect: +5′-CCGGCGCTGCTCTCATCCCGGT-3′ and −5′-GGCCGAACATAGTCCCCCAGAG-3′ for Tax. The correct primers are listed as follows: +5′-CCGGCGCTGCTCTCATCCCGGT-3′ and −5′-GGCCGAACATAGTCCCCCAGAG-3′ for Tax in HTLV-1-infected and ATL-derived cell lines; +5′-ATCGGCTCAGCTCTACAGTTCCT-3′ and −5′-ATTCGCTTGTAGGGAACATTGGT-3′ for Tax in JPX-9 and JPX-M cells.
