Dispute with “unlisted author whose claim to authorship could not be solved” topples cancer paper
The article, “Antitumor activity of human γδ T cells transducted with CD8 and with T-cell receptors of tumor-specific cytotoxic T lymphocytes,” appeared online in July 2012 and was written, ostensibly, by Takeshi Hanagiri, Yoshiki Shigematsu, Koji Kuroda, Tetsuro Baba, Hironobu Shiota, Yoshinobu Ichiki, Yoshika Nagata, Manabu Yasuda, Tomoko So, Mitsuhiro Takenoyama and Fumihiro Tanaka from the Second Department of Surgery at the University of Occupational and Environmental Health, in Kitakyushu.
The abstract states:
The difficulty in the induction and preparation of a large number of autologous tumor-specific cytotoxic T lymphocytes (CTL) from individual patients is one of major problems in their application to adoptive immunotherapy. The present study tried to establish the useful antitumor effectors by using γδ T cells through tumor-specific TCRαβ genes transduction, and evaluated the efficacy of their adoptive transfer in a non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice model. The TCRαβ gene was cloned from the HLA-B15-restricted CTL clone specific of the Kita-Kyushu Lung Cancer antigen-1 (KK-LC-1). The cloned TCRαβ as well as the CD8 gene were transduced into γδ T cells induced from peripheral blood lymphocytes (PBL). Cytotoxic T lymphocyte activity was examined using a standard 4 h 51Cr release assay. Mice with a xenotransplanted tumor were treated with an injection of effector cells. Successful transduction of TCRαβ was confirmed by the staining of KK-LC-1-specific tetramers. The γδ T cells transduced with TCRαβ and CD8 showed CTL activity against the KK-LC-1-positive lung cancer cell line in a HLA B15-restricted manner. Adoptive transfer of the effector cells in a mice model resulted in marked growth suppression of KK-LC-1- and HLA-B15-positive xenotransplanted tumors. Co-transducing TCRαβ and CD8 into γδ T cells yielded the same antigen-specific activity as an original CTL in vitro and in vivo. The TCRαβ gene transduction into γδ T cells is a promising strategy for developing new adoptive immunotherapy. (Cancer Sci, doi: 10.1111/j.1349-7006.2012.02337.x, 2012)
