Figure Lengend Snippet: (A) UMAP plot showing unbiased clustering of CD8+ T cells based on the immune markers CD103, CD69, CD27, CCR7, CD127, CCR5, CD28, HLA-DR, CD38, 287 PD1, CD39, TIGIT. (B) UMAP plots of expression levels of selected immune markers in TB-PE-derived CD8+ T cells. (C) Proportions of CD8+ T cell clusters identified by UMAP analysis. (D) Heatmap of average expression of 12 variably expressed markers across clusters. (E) scRNA/TCR-seq analysis of TB-PE-derived CD8+ T cells from one PLWH/TB, showing TCR specificities for viral antigens. Cytokine and cytotoxic signatures from scRNAseq data are shown (top), with a heatmap of TNF, IFNG, GZMA, and GZMB expression (bottom). (F) Exhaustion signature from scRNAseq data (top), with a heatmap showing relative expression of exhaustion-associated genes TIGIT, LAG3, CTLA4, PDCD1, and HAVCR2 (bottom).
