Description
We examined the brain''s choroid plexus and myeloid cell populations isolated from the brain of 5XFAD Alzheimer''s disease transgenic mice following PD-1 blockade Overall design: Choroid plexus samples and myeloid cell populations were isolated from the brain of 5XFAD mice following PD-1 blockade, and sequenced. For choroid plexus samples, 5 mice were treated with anti-PD-1, 5 with IgG control, and 4 were left untreated. For the myeloid cells samples, myeloid cells sorted from the brains of 5XFAD mice according to a gating strategy that seperate microglia (CD11b+CD45-low) and monocytes-derived macrophages (CD11b+CD45-high).

Description
Alzheimer''s disease (AD) is a detrimental neurodegenerative disease with no effective treatments. Due to cellular heterogeneity, the roles of immune cell subsets in AD onset and progression are poorly understood. By transcriptional single cell sorting, we comprehensively map all immune populations in wild type and AD–transgenic (Tg-AD) mouse brains. We describe a novel microglia type associated with neurodegenerative diseases (DAM) and identify the markers, spatial-location, and pathways associated with these cells. Immunohistochemical staining of mice and human brain slices showed DAM with intracellular/phagocytic Aß particles. Single cell analysis of DAM in Tg-AD and Trem2-/- Tg-AD revealed that the DAM program is activated in a two-step process. Activation is initiated in a Trem2 independent manner which involves down-regulation of microglia checkpoints, followed by activation of a Trem2-dependent program. These data identify a unique microglia-type, which may have important implications for future treatment of AD and other neurodegenerative diseases. Overall design: Transcriptional profiling of single cells from immune populations of mouse models of neurodegenerative diseases with matched controls, generated from deep sequencing of tens of thousands of cells, sequenced in several batches on illumina Nextseq500

Description
The mammalian liver consists of hexagonal-shaped lobules, radially polarized by blood flow and morphogens. Key liver genes have been shown to be differentially expressed along the lobule axis, a phenomenon termed zonation, but a detailed genome-wide reconstruction of this spatial division of labor has not been achieved. Here we measure the whole transcriptome of thousands of single mouse liver cells and infer their lobule coordinates using a panel of zonated landmark genes, characterized with single-molecule FISH. We obtain a genome-wide reconstruction of liver zonation profiles with unprecedented spatial resolution. We find that more than 50% of liver genes are significantly zonated and uncover abundant non-monotonic profiles that peak at the mid-lobule layers. Our approach can facilitate reconstruction of similar spatial genomic blueprints for other mammalian organs. Overall design: mRNA profiles from single cells extracted from mouse liver were generated by deep sequencing of 1736 of single cells, sequenced in several batches in an Illumina NextSeq.

Description
Microglia play important roles in life-long brain maintenance and in pathology, but are also crucial in the developing central nervous system; yet their regulatory dynamics during development have not been fully elucidated. Genome-wide chromatin and expression profiling coupled with single-cell transcriptomic analysis throughout development reveal that microglia undergo three temporal developmental stages in synchrony with the brain: early, pre-, and adult microglia, which are under the control of distinct regulatory circuits. Knockout of the transcription factor MafB caused disruption of homeostasis in adulthood and increased inflammation. Environmental perturbations, such as the microbiome or prenatal immune activation, led to dysregulation of the developmental program, particularly in terms of inflammation. Together, our work identifies a stepwise developmental program of microglia integrating immune response pathways that may be associated with several neurodevelopmental disorders. Overall design: Yolk sac progenitors (CD45+CD11B+CX3CR1-GFP+), microglia from early brain (CD45+CD11B+CX3CR1-GFP+), and microglia from later stages (CD45intCD11BintCX3CR1-GFP+) were isolated from CX3CR1+ C57BL/6J mice or microglia from perturbation models (CD45intCD11Bint) from mice of C57BL/6J background

Description
Scope: As a result of population ageing, the number of Alzheimer’s disease (AD) patients has rapidly increased. There are many hypothesises on the pathogenesis of AD, but its detailed molecular mechanism is still unknown, and so no effective preventive or therapeutic measures have been established. Some reports showed a decrease in levels of norepinephrine (NE) has been suspected to be involved in the decline of cognitive function in AD patients and NE concentrations were decreased in postmortem AD patient brains. Tyr-Trp was identified as being the most effective dipeptide in enhancing norepinephrine (NE) synthesis and metabolism. And Tyr-Trp treatment ameliorated the short-term memory dysfunction in AD model mice caused by amyloid beta (Aβ) 25-35. So, the purpose of this study was to investigate the preventive or/and protective effects of Tyr-Trp administration in AD model mice.

Tyr-Trp administration facilitates brain norepinephrine metabolism and ameliorates a short-term memory deficit in a mouse model of Alzheimer's disease.

Description
The mouse anterior-posterior (A-P) axis polarization is preceded by formation of the distal visceral endoderm (DVE). However, the mechanism of the emergence of DVE cells is not well understood. Here, we show by in vitro culturing of embryos immediately after implantation in micro-fabricated cavities (narrow; 90 micro-meter, wide; 180 miro-meter in diameter) that the external mechanical cues exerted on the embryo, i.e. cultured in the narrow cavity, are crucial for DVE formation as well as elongated egg cylinder shape. This implies that these developmental events immediately after implantation are not simply embryo-autonomous processes but require extrinsic mechanical factors. Further whole genome-wide gene expression profiles with DNA microarray revealed that no significant difference of transcripts were evident with or without mechanical cues except DVE-related markers. Thus, we propose that external mechanical cues rather than not specific molecular pathways can trigger the establishment of the A-P axis polarization, which is one of the fundamental proccesses of mammalian embryogenesis.

Description
Ovarian clear cell carcinoma (OCCC) shows unique clinical features including an association with endometriosis and poor prognosis. We previously reported that the contents of endometriotic cysts, especially high concentrations of free iron, are a possible cause of OCCC carcinogenesis through iron-induced persistent oxidative stress. In this study, we conducted gene expression microarray analysis using 38 ovarian cancer cell lines and identified genes commonly expressed in both OCCC cell lines and clinical samples, which comprise an OCCC gene signature. The OCCC signature reproducibly predicts OCCC specimens in other microarray data sets, suggesting that this gene profile reflects the inherent biological characteristics of OCCC. The OCCC signature contains known markers of OCCC, such as hepatocyte nuclear factor-1b (HNF-1b) and versican (VCAN), and other genes that reflect oxidative stress. Expression of OCCC signature genes was induced by treatment of immortalized ovarian surface epithelial cells with the contents of endometriotic cysts, indicating that the OCCC signature is largely dependent on the tumor microenvironment. Induction of OCCC signature genes is at least in part epigenetically regulated, as we found hypomethylation of HNF-1b and VCAN in OCCC cell lines. This genomewide study indicates that the tumor microenvironment induces specific gene expression profiles that contribute to the development of distinct cancer subtypes.
