Fig. 5From: BCL-2 expression promotes immunosuppression in chronic lymphocytic leukemia by enhancing regulatory T cell differentiation and cytotoxic T cell exhaustionCytokines secreted from Tregs in BCL-2-positive and -negative CD4+T cells in patients with CLL (n = 45). (a), (c), and (e) Representative examples of IL-10, TGF-β, and IL-35 in BCL-2+ and BCL-2− Tregs. (b), (d), and (f) Percentage positive and MFI of IL-10, TGF-β, and IL-35 among Tregs between BCL-2-positive and -negative T cells. Differences are shown in scatter plots (*p < 0.05; ns, not significant)Back to article page
