Abstrakt: T cells and dendritic cells (DCs) that are positive for the tissue-resident marker CD103 play a vital role in antitumor immunity. In this study, multiplexed immunohistochemistry was applied to stain CD103 and the T-cell marker CD8 as well as the DC marker CD11c on formalin-fixed, paraffin-embedded oral squamous cell carcinoma (OSCC) tissues. Then, the density of CD103+CD8+ and CD103+CD11c+ tumor-infiltrating lymphocytes (TILs) in the intratumoral and stromal regions was calculated, and the correlation of CD103+CD8+ TIL and CD103+CD11c+ TIL density with OSCC patient prognosis was analyzed. The results revealed that CD103+CD8+ TILs and CD103+CD11c+ TILs were abundant in the stromal region and that increased stromal CD103+CD8+ TIL and intratumoral CD103+CD11c+ TIL density indicated a favorable prognosis. Moreover, we freshly isolated TILs from OSCC samples and performed flow cytometry to verify that CD103+CD8+ TILs display a tissue-resident memory T-cell (Trm) phenotype, and we discriminated CD103+CD11c+ TILs from tumor-associated macrophages.
