RNA-seq of dendritic cell subsets


ABSTRACT: Comparison of cDC1, cDC2, mcDC transcriptome Conventional dendritic cells (cDCs) are classically subdivided in two subsets, named cDC1 and cDC2. We demonstrated that mcDC are a new subset of cDCs. To understand their transcriptomic relatedness, we perform a RNA sequencing on cDC1, cDC2 and mcDCs sorted from mouse spleens. We demonstrate that cDC1, cDC2 and mcDCs all cluster independently in a PCA analysis and an unbiased hierarchical cluster analysis reveals unique gene profile for all three cDC subsets. As mcDC cluster slightly more towards cDC1 than cDC2, we next aimed to more closely examine the transcriptomic relatedness between mcDC and cDC2. We compared the DC subsets gene expression signatures based on a selected gene set known to define cDC2. Both the PCA and hierarchical cluster analysis show that mcDC exhibit a different signature to cDC2. Altogether, we demonstrate that mcDC are a distinct subsets of cDCs with a specific transcriptomic signature.
