Th17 Cell Therapy Diagram (IMAGE) Medical University of South Carolina Caption A faster approach for T-cell therapy against cancer. Knochelmann and colleagues show a subset of CD4 T-cells, Th17 cells, can effectively kill tumor cells when they are grown in cell culture for only four days. Th17 cells grown for shorter or longer periods of time cannot successfully eradicate the tumor. Additionally, the cytokine IL-6 is produced by the day-four Th17 cells, which supports the tumor-eradicating functions of the Th17 cells.
