Retraction: Immunity to Murine Prostatic Tumors: Continuous Provision of T-Cell Help Prevents CD8 T-Cell Tolerance and Activates Tumor-Infiltrating Dendritic Cells

The editors and authors retract the article titled “Immunity to Murine Prostatic Tumors: Continuous Provision of T-Cell Help Prevents CD8 T-Cell Tolerance and Activates Tumor-Infiltrating Dendritic Cells,” which was published in the August 1, 2009 issue of Cancer Research (1), based on the findings of data falsification regarding Fig. 6A. Following review by an NIH investigation committee, NIH found the author Stephanie Watkins was the sole individual responsible for the instances of research misconduct. None of the other authors were aware of the misconduct.

Seven of the eight authors have agreed to this retraction and they are as follows:
