View SamplesInnate sensing of viruses by dendritic cells (DCs) is critical for the initiation of anti-viral adaptive immune responses. Virus, however, have evolved to suppress immune activation in infected cells. We now analyze the susceptibility of different populations of dendritic cells to viral infections. We find that circulating human CD1c+ DCs support infection by HIV and influenza virus. Viral infection of CD1c+ DCs is essential for virus-specific CD8+ T cell activation and cytosolic sensing of the virus. In contrast, circulating human CD141+ DCs and pDCs constitutively limit viral fusion. The small GTPase RAB15 mediates this differential viral resistance in DC subsets through selective expression in CD141+ DCs and pDCs. Therefore, dendritic cell sub-populations evolved constitutive resistance mechanisms to mitigate viral infection during induction of antiviral immune response. Overall design: Examination of transcriptional profiles in 4 DC subsets purified from 3 donors using RNASeq

View SamplesWe performed single-cell RNA-seq on CD14+ monocytes isolated from the blood of healthy donors. Using the 10x chromium technology, we analyzed 425 and 431 cells from 2 individual donors. Overall design: Peripheral Blood Mononuclear Cells (PBMC) were prepared by centrifugation on a Ficoll gradient. Blood CD14+ monocytes were isolated from healthy donors' PBMC by positive selection using magnetic beads. Monocytes were 93-95% CD14+CD16- as assessed by flow cytometry. Cellular suspensions (1700 cells) were loaded on a 10X Chromium instrument (10X Genomics) according to manufacturer's protocol.

View SamplesWe performed single-cell RNA-seq on CD4 T cells isolated from the tonsils of one healthy donor. We used the 10x chromium technology. Overall design: Tonsil CD4 T cells were enriched by negative selection using magnetic beads. Cell populations (CXCR5+PD-1low T cells, CXCR5+PD-1int T cells and CXCR5+PD-1high T cells ) were further isolated by cell sorting. Cellular suspensions (3500 cells) were loaded on a 10X Chromium instrument (10X Genomics) according to manufacturer's protocol.

The dynamics of gene expression changes in a mouse model of oral tumorigenesis may help refine prevention and treatment strategies in patients with oral cancer.
