We have used RNA-seq analysis to define genes differentially expressed between APC subpopulations that could (CD1c+, SLAN+, CD14+ monocytes) and could not induce latent infection (pDC), and identified genes mediating cell adhesion, T-cell activation, immune checkpoints (IC) and regulation of apoptosis as important pathways differentially upregulated in the APC that are able to induce latent infection. Here, CD1C is linked to disease arising from reactivation of latent virus.
