In this article, we identified bona fide cDCs in chicken spleen. Comparative profiling of global and of immune response gene expression, morphology, and T cell activation properties show that cDCs and macrophages (MPs) exist as distinct mononuclear phagocytes in the chicken, resembling their human and mouse cell counterparts. With computational analysis, core gene expression signatures for cDCs, MPs, and T and B cells across the chicken, human, and mouse were established, which will facilitate the identification of these subsets in other vertebrates. Overall, this study, by extending the newly uncovered cDC and MP paradigm to the chicken, suggests that these two phagocyte lineages were already in place in the common ancestor of reptiles (including birds) and mammals in evolution.

  • Inhibition of Mitochondrial Complex II in Neuronal Cells Triggers Unique
    www.nature.com/scientificreports OPEN Inhibition of mitochondrial complex II in neuronal cells triggers unique pathways culminating in autophagy with implications for neurodegeneration Sathyanarayanan Ranganayaki1, Neema Jamshidi2, Mohamad Aiyaz3, Santhosh‑Kumar Rashmi4, Narayanappa Gayathri4, Pulleri Kandi Harsha5, Balasundaram Padmanabhan6 & Muchukunte Mukunda Srinivas Bharath7* Mitochondrial dysfunction and neurodegeneration underlie movement disorders such as Parkinson’s disease, Huntington’s disease and Manganism among others. As a corollary, inhibition of mitochondrial complex I (CI) and complex II (CII) by toxins 1‑methyl‑4‑phenylpyridinium (MPP+) and 3‑nitropropionic acid (3‑NPA) respectively, induced degenerative changes noted in such neurodegenerative diseases. We aimed to unravel the down‑stream pathways associated with CII inhibition and compared with CI inhibition and the Manganese (Mn) neurotoxicity. Genome‑wide transcriptomics of N27 neuronal cells exposed to 3‑NPA, compared with MPP+ and Mn revealed varied transcriptomic profle. Along with mitochondrial and synaptic pathways, Autophagy was the predominant pathway diferentially regulated in the 3‑NPA model with implications for neuronal survival. This pathway was unique to 3‑NPA, as substantiated by in silico modelling of the three toxins. Morphological and biochemical validation of autophagy markers in the cell model of 3‑NPA revealed incomplete autophagy mediated by mechanistic Target of Rapamycin Complex 2 (mTORC2) pathway.

    www.nature.com/scientificreports OPEN Functional characterization of TBR1 variants in neurodevelopmental disorder Received: 14 May 2018 Joery den Hoed1, Elliot Sollis1, Hanka Venselaar2, Sara B. Estruch1, Pelagia Deriziotis1 & Accepted: 31 August 2018 Simon E. Fisher 1,3 Published: xx xx xxxx Recurrent de novo variants in the TBR1 transcription factor are implicated in the etiology of sporadic autism spectrum disorders (ASD). Disruptions include missense variants located in the T-box DNA- binding domain and previous work has demonstrated that they disrupt TBR1 protein function. Recent screens of thousands of simplex families with sporadic ASD cases uncovered additional T-box variants in TBR1 but their etiological relevance is unclear. We performed detailed functional analyses of de novo missense TBR1 variants found in the T-box of ASD cases, assessing many aspects of protein function, including subcellular localization, transcriptional activity and protein-interactions. Only two of the three tested variants severely disrupted TBR1 protein function, despite in silico predictions that all would be deleterious. Furthermore, we characterized a putative interaction with BCL11A, a transcription factor that was recently implicated in a neurodevelopmental syndrome involving developmental delay and language defcits. Our fndings enhance understanding of molecular functions of TBR1, as well as highlighting the importance of functional testing of variants that emerge from next-generation sequencing, to decipher their contributions to neurodevelopmental disorders like ASD. TBR1 (T-box brain, 1; OMIM *604616) encodes a neuron-specifc transcription factor of the T-box family1. Te TBR1 protein is highly expressed in the deep layers of the cortex, where it is involved in diferentiation of subsets of projection neurons2–4.

    Science Bulletin 64 (2019) 1562–1564 Contents lists available at ScienceDirect Science Bulletin journal homepage: www.elsevier.com/locate/scib Research Highlight Reduction of BCL11A in hematopoietic stem cells through gene editing: new strategy to ameliorate the severe b-globin disorders sickle cell disease ⇑ Weiqi Hong, Mengyuan Huang, Yuquan Wei, Xiawei Wei Laboratory of Aging Research and Cancer Drug Target, State Key Laboratory of Biotherapy, National Clinical Research Center for Geriatrics, West China Hospital, Sichuan University, Chengdu 610041, China Site-specific gene editing is of great importance in precise Sickle-cell anemia is a prototypical monogenic disorder caused medicine. Two conventional genome editing methods, Zine finger by mutation of b-globin subunit. It is a promising therapy strategy nucleases (ZFNs) and transcription activator-like effector nucleases to induct fetal hemoglobin (HbF, a2c2) by re-expressing the paral- (TALENs), are based on protein-DNA recognition, with tedious ogous c-globin genes (HBG1/2) for severe b-globin disorders sickle work in constructing target protein [1,2]. Developed from immune cell disease (SCD) and b-thalassemia [9]. Researches in the past response of bacteria, CRISPR/Cas9 has been widely investigated as have shown that the core of the +58 erythroid enhancer of BCL11A a promising tool for therapeutic genome editing in clinical settings was crucial for repression of HBF in adult stage erythroid. Wu et al nowadays [3,4]. This system succeeds in gene deletion, insertion found that chemically modified synthetic sgRNAs (MS-sgRNAs) and frameshift mutations with higher efficiency, less cost, was more efficient than in vitro transcribed sgRNAs. Targeting improved flexibility and simplified designing process [5].

  • Characterization of Transcription Factor Networks Involved in Umbilical Cord Blood CD34+ Stem Cells-Derived Erythropoiesis
    Characterization of Transcription Factor Networks Involved in Umbilical Cord Blood CD34+ Stem Cells-Derived Erythropoiesis Biaoru Li1, Lianghao Ding2, Chinrang Yang2, Baolin Kang1, Li Liu3, Michael D. Story2, Betty S. Pace1* 1 Department of Pediatrics, Hematology/Oncology Division, Georgia Regents University, Augusta, Georgia, United States of America, 2 Department of Radiation Oncology and Simmons Comprehensive Cancer Center, University of Texas Southwestern Medical Center, Dallas, Texas, United States of America, 3 Department of Molecular and Cell Biology, University of Texas at Dallas, Richardson, Texas, United States of America Abstract Fetal stem cells isolated from umbilical cord blood (UCB) possess a great capacity for proliferation and differentiation and serve as a valuable model system to study gene regulation. Expanded knowledge of the molecular control of hemoglobin synthesis will provide a basis for rational design of therapies for b-hemoglobinopathies. Transcriptome data are available for erythroid progenitors derived from adult stem cells, however studies to define molecular mechanisms controlling globin gene regulation during fetal erythropoiesis are limited. Here, we utilize UCB-CD34+ stem cells induced to undergo erythroid differentiation to characterize the transcriptome and transcription factor networks (TFNs) associated with the c/b-globin switch during fetal erythropoiesis. UCB-CD34+ stem cells grown in the one-phase liquid culture system displayed a higher proliferative capacity than adult CD34+ stem cells. The c/b-globin switch was observed after day 42 during fetal erythropoiesis in contrast to adult progenitors where the switch occurred around day 21. To gain insights into transcription factors involved in globin gene regulation, microarray analysis was performed on RNA isolated from UCB-CD34+ cell-derived erythroid progenitors harvested on day 21, 42, 49 and 56 using the HumanHT-12 Expression BeadChip.
