Fig. 4From: Repeated cycles of 5-fluorouracil chemotherapy impaired anti-tumor functions of cytotoxic T cells in a CT26 tumor-bearing mouse modelAbsolute number of proliferated immune cells after 5-FU C1 and C3. Proliferated immune cells were detected by CFSE assay, and the absolute numbers of proliferated CD4 T-cells (a), CD8 T-cells (b), NK cells (c) and B cells (d) were calculated. The significance between groups was analyzed by Student’s t-test. The results are representatives of at least three independent experimentsBack to article page
