Alteration of peripheral frequencies of regulatory lymphocytes in patients with lung cancer. A: peripheral frequency of CD4⁺ T cells in total peripheral blood mononuclear cells (PBMCs), B: peripheral frequency of CD19⁺ B cells in total PBMCs, C: peripheral frequency of Tregs in CD4⁺ T cells, D: peripheral frequency of CD45RA⁺Tregs in CD4⁺ T cells, E: peripheral frequency of CD19⁺CD24^hiCD27⁺ B cells in CD19⁺ B cells, and F: peripheral frequency of CD19⁺IL-10⁺ B cells in CD19⁺ B cells. * and *** stand for p value less than 0.05 and 0.001, as compared to healthy control, respectively.
