This analysis showed, in tumor samples, an increased percentage of CCR6+ CD8+ T cells expressing both CCR5 and CXCR3 (p < 0.01) and a decrease of Th17 and Tc17 cells expressing only CCR5 (p < 0.01 and p < 0.0001, respectively) and an increase of Tc17 cells expressing only CXCR3 (p < 0.0001). The gene discussed is CCR6; the disease is neoplasm.
