Fig. 4From: Exploring the relationship between Treg-mediated risk in COPD and lung cancer through Mendelian randomization analysis and scRNA-seq data integrationSingle-cell sequencing reveals the dynamic changes of T cell subtypes in COPD and lung cancer. (A) The expression of marker genes in T cells. (B) UMAP plot showing the subtypes of T cells. (C) Stacked barplot comparing the relative frequencies of each T cell subtype among COPD, lung cancer and normal samples. (D) Boxplots showing the distribution of frequencies for each T cell subtype across different sample groupsBack to article page
