Fig. 2From: Combining single-cell RNA sequencing of peripheral blood mononuclear cells and exosomal transcriptome to reveal the cellular and genetic profiles in COPDIdentification of exosomal differentially expressed mRNAs, lncRNAs, and circRNAs in COPD. Volcano plots of exosomal differentially expressed A mRNAs, B lncRNAs, and C circRNAs. The green dots represent the downregulated genes, while the red dots represent the upregulated genes.
