Description
We provide a map of human ILC heterogeneity across multiple anatomical sites. Tissue-specific distinctions are particularly apparent for ILC1 populations, whose distribution was markedly altered in obesity or aging. Furthermore, the degree of ILC1 population hetero- geneity differed substantially in lymphoid versus mucosal sites. Together, these analyses comprise a comprehensive characterization of the spatial and temporal dynamics regulating the anatomical distri- bution, subset heterogeneity, and functional poten- tial of ILCs in non-diseased human tissues. Overall design: We present a quantitative analysis of ILC distribution and heterogeneity in lymphoid, mucosal, and metabolic tissues obtained from a diverse cohort of 44 previously non-diseased organ donors over a wide range of ages and body mass indexes (BMIs).

Description
The type 2 cytokines interleukin (IL)-4, IL-5, IL-9 and IL-13 play critical roles in stimulating innate and adaptive immune responses required for resistance to helminth infection and promotion of allergic inflammation, metabolic homeostasis and tissue repair. Group 2 innate lymphoid cells (ILC2s) are a potent source of type 2 cytokines and while significant advances have been made in understanding the cytokine milieu that promotes ILC2 responses, there are fundamental gaps in knowledge regarding how ILC2 responses are regulated by other stimuli. In this report, we demonstrate that ILC2s in the gastrointestinal tract co-localize with cholinergic neurons that express the neuropeptide neuromedin U (NMU). In contrast to other hematopoietic cells, ILC2s selectively express the NMU receptor 1 (NMUR1). In vitro stimulation of ILC2s with NMU induced rapid cell activation, proliferation and secretion of type 2 cytokines IL-5, IL-9 and IL-13 that was dependent on cell-intrinsic expression of NMUR1 and Gaq protein. In vivo administration of NMU triggered potent type 2 cytokine responses characterized by ILC2 activation, proliferation and eosinophil recruitment that was associated with accelerated expulsion of the gastrointestinal nematode Nippostrongylus brasiliensis or induction of lung inflammation. Conversely, worm burden was higher in Nmur1-/- mice compared to control mice. Further, use of gene-deficient mice and adoptive cell transfer experiments revealed that ILC2s were necessary and sufficient to mount NMU-elicited type 2 cytokine responses. Together, these data indicate that the NMU-NMUR1 neuronal signaling circuit provides a selective and previously unrecognized mechanism through which the enteric nervous system and innate immune system integrate to promote rapid type 2 cytokine responses that can induce anti-microbial, inflammatory and tissue-protective type 2 responses at mucosal sites. Overall design: To assess changes in gene expression in ILC2s due to NMU treatment, RNAseq was performed on 3 samples from NMU-treated mice and 4 samples from PBS-treated mice.

Description
TGZ is an agonist of the nuclear receptor PPARgamma. This synthetic compound displays anticancer effects on breast cancer cells but some of them are PPARgamma independent. Delta-2-TGZ (delta-2-troglotazone) is a PPARgamma inactive TGZ derivative possessing a double bond adjoining the thiazolidinedione ring. This compound still displays anticancer efefcts. It is an interesting tool to study the PPARgamma-independent mechanisms.

Description
Purpose: Single-cell RNA sequencing has revolutionized cell-type specific gene expression analysis. The goals of this study are to compare cell specific gene expression patterns between retinal cell types originating from the fovea and the periphery of human eyes. Methods: Independent libraries were prepared for foveal and peripheral samples of neural retina from three donors using the 10x Chromium system. Libraries were sequenced on a HiSeq4000. Sequenced reads were mapped to the human genome build hg19 will CellRanger(v3.0.1) and filters removed cells likely to be doublets or cells with a high proportion of mitochondrial reads. Clustering of cells with similar expression profiles was performed with Seurat (v2.3.4). Results: Independent libraries were prepared for foveal and peripheral samples of neural retina from three donors using the 10x Chromium system. Libraries were sequenced on a HiSeq4000. Sequenced reads were mapped to the human genome build hg19 will CellRanger(v3.0.1) and filters removed cells likely to be doublets or cells with a high proportion of mitochondrial reads. Clustering of cells with similar expression profiles was performed with Seurat (v2.3.4). Conclusions: Our study generates a large atlas of human retinal transcriptomes at the single cell level. We identified the majority of expected neural and supportive cell types, and describe regional differences in gene expression between the fovea and the periphery. Our results show that that single-cell RNA sequencing can be performed on human retina after cryopreservation, and that cone photoreceptors and Muller cells demonstrate region-specific patterns of gene expression. Overall design: mRNA profiles for thousands of cells from foveal and peripheral retinal isolates were generated from three human donor eyes using 10X Genomics Chromium single-cell system followed by sequencing on an Illumina HiSeq 4000.

Description
Basic helix-loop-helix (bHLH) proneural transcription factors (TFs) Ascl1 and Neurog2 are integral to the development of the nervous system. Here, we investigated the molecular mechanisms by which Ascl1 and Neurog2 control the acquisition of generic neuronal fate and impose neuronal subtype identity. Using direct neuronal programming of embryonic stem cells, we found that Ascl1 and Neurog2 regulate distinct targets by binding to largely different sets of sites. Their divergent binding pattern is not determined by the previous chromatin state but distinguished by specific E-box enrichments which reflect the DNA sequence preference of the bHLH domain. The divergent Ascl1 and Neurog2 binding patterns result in distinct chromatin accessibility and enhancer activity landscapes that shape the binding and activity of downstream TFs during neuronal specification. Our findings suggest that proneural factors contribute to neuronal diversity by differentially altering the chromatin landscapes that shape the binding of neuronally expressed TFs. Overall design: Single-cell RNA-seq was used to characterize gene expression in mixed populations of mES cells containing induced expression of either Ascl1 or Neurog2.
