Abstract

Adult T-cell leukemia/lymphoma (ATLL), an aggressive type of malignant lymphoma, is highly resistant to chemotherapy. However, the detailed mechanisms of the chemoresistance of ATLL have never been elucidated. We previously demonstrated that direct cell‑cell interaction between macrophages and lymphoma cells was significantly associated with lymphoma progression in patients with ATLL. The present study aimed to further analyze the effects of cell‑cell interaction between macrophages and ATLL cells by means of cell culture studies and immunohistochemical analysis using human ATLL samples. It was found that direct co‑culture with macrophages induced chemoresistance in the ATLL ATN‑1 cell line, but not in other cell lines, including TL-Mor, ED and ATL-2S. It was also found that expression of the T cell Ig and mucin domain‑containing molecule‑3 (TIM‑3) was induced in ATN‑1 cells by their long‑term co‑culture with macrophages. TIM‑3 gene transfection induced chemoresistance in the ATN‑1 cells. Immunostaining of ATLL tissues showed TIM‑3 expression in 25 out of 58 ATLL cases. Although TIM‑3 expression was not associated with overall survival or T classification, it was associated with resistance to chemotherapy. TIM‑3 expression is therefore considered to be a marker for predicting the efficacy of chemotherapy, and TIM‑3‑associated signals may be a therapeutic target for patients with ATLL.
