Description
The phenotypic and functional dichotomy between IRF8+ type 1 and IRF4+ type 2 conventional dendritic cells (cDC1-cDC2) is well accepted; it is unknown how robust this dichotomy is under inflammatory conditions, when additionally monocyte-derived cells (MCs) become competent antigen presenting cells (APC). Using single-cell technologies in models of respiratory viral infection, we found that lung cDC2s acquired expression of Fc receptor CD64 shared with MCs, and of IRF8 shared with cDC1s. These inflammatory (Inf-)cDC2s were superior in inducing CD4+ T helper (Th) cell polarization while simultaneously presenting antigen to CD8+ T cells. When carefully separated from inf-cDC2s, MCs lacked APC function. Inf-cDC2 matured in response to cell-intrinsic toll-like receptor and type 1 interferon receptor signaling, upregulated an IRF8-dependent maturation module and acquired antigens via convalescent serum and Fc receptors. Since hybrid inf-cDC2s are easily confused with monocyte-derived cells, their existence could explain why APC functions have been attributed to MCs.

Description
FNDC4 is a novel secreted factor sharing high homology with the exercise-associated myokine irisin (FNDC5). Here we report that Fndc4 is robustly upregulated in various mouse models of inflammation as well as in human inflammatory conditions. Specifically, subjects with inflammatory bowel disease show increased FNDC4 levels locally at inflamed sites of the intestine. Interestingly, administration of recombinant FNDC4 during colitis development in mice resulted in markedly reduced disease severity compared to mice injected with a control protein. Conversely, mice that lacked Fndc4 showed increased colitis severity. Analysis of binding of FNDC4 to different immune cell types revealed strong and specific binding to macrophages and monocytes. FNDC4 treatment of bone marrow-derived macrophages in vitro resulted in reduced phagocytosis, improved survival and reduced pro-inflammatory chemokine expression. Hence, treatment with FNDC4 resulted in a state of dampened macrophage activity, while enhancing their survival. Thus, we have characterized a novel factor with direct therapeutic potential in inflammatory bowel disease and possibly other inflammatory diseases.

Description
Transformation of Glycine max with seed-targeted expression vectors via Agrobacterium causes measurable unscripted gene expression changes in the seed transcriptome Overall design: mRNA was sequenced from three transgenic events expressing three different recombinant proteins in soybean seeds. Three plants were chosen from each as group replicates, and three seeds from each plant as individual biological replicates.

Description
CTSK-mGFP positive cells from Day 6 old mouse femurs were sorted as single cells into 384 well plates pre-loaded with unique barcoded RT-primers. After sorting, cells were snap frozen on dry ice before being submitted to the New York Genome Center (NYGC) for cDNA synthesis and library preparation. The FACS profile for all the sored cells were collected to co-relate with gene expression. Overall design: Mouse femur was obtained from mice within the same litter. Femur samples was subjected to collagenase digestion, and single cell suspension was obtained. The samples were stained for FACS antibodies and single cell sorting was performed into two individual 384 well plates. The experiment has two replicates from two independant animals. The samples were always kept discrete.

Description
The immune system generates pathogen-tailored responses. The precise innate immune cell types and pathways that direct robust adaptive immune responses have not been fully characterized. By using fluorescent pathogens combined with massively parallel single cell RNA-seq, we comprehensively characterized the initial 48 hours of the innate immune response to diverse pathogens. We found that across all pathogens tested, most of the lymph node cell types and states showed little pathogen-specificity. In contrast, the rare antigen-positive cells displayed pathogen-specific transcriptional programs as early as 24 hours after immunization. In addition, mycobacteria activated a specific NK driven IFN? response. Depletion of NK cells and IFN? showed that IFN? initiated a monocyte specific signaling cascade, leading to production of major chemokines and cytokines that promote Th1 development. Our systems immunology approach sheds light on early events in innate immune responses and may help further development of safe and efficient vaccines. Overall design: Transcriptional profiling of single cells from pathogen-injected mouse auricular lymph nodes, generated from deep sequencing of thousands of cells, sequenced in several batches on illumina Nextseq500. For all experiments, innate immune lymph node cells were sorted accordng to the markers indicated in Samples' Characteristics "selection marker" field into 384-well MARS-seq2.0 cell capture plates. Sorting of antigen-carrying cells (Ag+) was based on the AF488-fluorescence of the pathogens injected. Different pathogens and time points were used, as indicated in the Samples' Characteristics "infection" and "time points" fields.
