To characterize the potential chemokine/chemokine receptor axes involved in the localization of Trm CD8+ T cells in the ovarian cancer tumor microenvironment (TME), we profiled the expression of the known chemokine receptors in Trm (CD3+CD8+CD103+) versus non-Trm (CD3+CD8+CD103−) cells obtained from patients with ovarian cancer tumors using Realtime- quantitative polymerase chain reaction (RT-QPCR) and flow cytometry. The gene discussed is CD8A; the disease is ovarian cancer.
