Tissue-Resident Memory-Like CD8⁺ T Cells Exhibit Heterogeneous Characteristics in Tuberculous Pleural Effusion

Figure 5

Inhibitory characteristics of CD103⁺CD8⁺ T cells. (a) The phenotype of CTLA-4⁺CD8⁺ T cells from PFMCs, the expression of CTLA-4 on different CD45RO⁺CD8⁺ T subsets distinguished based on CD103 and CD69 was detected, and the (b) representative dot plots and (c) statistical data were shown. (d) The phenotype of FoxP3⁺CD25⁺CD8⁺ T cells from PFMCs, the coexpression of FoxP3 and CD25 in different CD45RO⁺CD8⁺ T subsets distinguished based on CD103 and CD69, and the (e) representative dot plots and (f) statistical data were shown (); and .
