Microglia Emerge from Erythromyeloid Precursors Via Pu.1- and Irf8-Dependent Pathways
ART ic LE S Microglia emerge from erythromyeloid precursors via Pu.1- and Irf8-dependent pathways Katrin Kierdorf1,2, Daniel Erny1, Tobias Goldmann1, Victor Sander1, Christian Schulz3,4, Elisa Gomez Perdiguero3,4, Peter Wieghofer1,2, Annette Heinrich5, Pia Riemke6, Christoph Hölscher7,8, Dominik N Müller9, Bruno Luckow10, Thomas Brocker11, Katharina Debowski12, Günter Fritz1, Ghislain Opdenakker13, Andreas Diefenbach14, Knut Biber5,15, Mathias Heikenwalder16, Frederic Geissmann3,4, Frank Rosenbauer6 & Marco Prinz1,17 Microglia are crucial for immune responses in the brain. Although their origin from the yolk sac has been recognized for some time, their precise precursors and the transcription program that is used are not known. We found that mouse microglia were derived from primitive c-kit+ erythromyeloid precursors that were detected in the yolk sac as early as 8 d post conception. + lo − + − + These precursors developed into CD45 c-kit CX3CR1 immature (A1) cells and matured into CD45 c-kit CX3CR1 (A2) cells, as evidenced by the downregulation of CD31 and concomitant upregulation of F4/80 and macrophage colony stimulating factor receptor (MCSF-R). Proliferating A2 cells became microglia and invaded the developing brain using specific matrix metalloproteinases. Notably, microgliogenesis was not only dependent on the transcription factor Pu.1 (also known as Sfpi), but also required Irf8, which was vital for the development of the A2 population, whereas Myb, Id2, Batf3 and Klf4 were not required. Our data provide cellular and molecular insights into the origin and development of microglia. Microglia are the tissue macrophages of the brain and scavenge dying have the ability to give rise to microglia and macrophages in vitro cells, pathogens and molecules using pattern recognition receptors and in vivo under defined conditions. -

ABSTRACT Thyroid cancer incidence, recurrence, and death rates are higher among Filipino Americans than European Americans. We propose that vitamin D binding protein (DBP) with multifunctionality with ethnic variability plays a key role within different ethnicities. In this study, we determined the correlation between differential DBP expression in tumor tissues and cancer staging in Filipino Americans versus European Americans. We assayed DBP expression by immunohistochemistry and analyzed the data with confocal microscopy on 200 thyroid cancer archival tissue samples obtained from both ethnicities. -

While these subtypes are known to originate from the embryonic caudal ganglionic eminence (CGE), the specific genetic programs that direct their positioning, maturation, and integration into the cortical network have not been eluci- dated. Here, we report that in mice expression of the transcription factor Prox1 is selectively maintained in postmitotic CGE-derived cortical interneuron precursors and that loss of Prox1 impairs the integration of these cells into superficial layers. Moreover, Prox1 differentially regulates the postnatal maturation of each specific subtype originating from the CGE (RELN, Calb2/VIP, and VIP). -

ABSTRACT The majority of gene loci that have been associated with type 2 diabetes play a role in pancreatic islet function. To evaluate the role of islet gene expression in the etiology of diabetes, we sensitized a genetically diverse mouse population with a Western diet high in fat (45% kcal) and sucrose (34%) and carried out genome-wide association mapping of diabetes-related phenotypes. We quantified mRNA abundance in the islets and identified 18,820 expression QTL. We applied mediation analysis to identify candidate causal driver genes at loci that affect the abundance of numerous transcripts. These include two genes previously associated with monogenic diabetes (PDX1 and HNF4A), as well as three genes with nominal association with diabetes-related traits in humans (FAM83E, IL6ST, and SAT2). We grouped transcripts into gene modules and mapped regulatory loci for modules enriched with transcripts specific for a-cells, and another specific for d-cells. -

ABSTRACT Pancreatic cancer (PC) is the fourth leading cause of cancer deaths in the United States with a five-year patient survival rate of only 6%. Early detection and treatment of this disease is hampered due to lack of reliable diagnostic and prognostic markers. Recent studies have shown that dynamic changes in the global DNA methylation and gene expression patterns play key roles in the PC development; hence, provide valuable insights for better understanding the initiation and progression of PC. In the current study, we used DNA methylation, gene expression, copy number, mutational and clinical data from pancreatic patients. -
Transcriptional Control of Microglia Phenotypes in Health and Disease
REVIEW SERIES: GLIA AND NEURODEGENERATION The Journal of Clinical Investigation Series Editors: Marco Colonna and David Holtzmann Transcriptional control of microglia phenotypes in health and disease Inge R. Holtman,1,2 Dylan Skola,1 and Christopher K. Glass1,3 1Department of Cellular and Molecular Medicine, UCSD, San Diego, California, USA. 2Department of Medical Physiology, University of Groningen, University Medical Center Groningen, Groningen, Netherlands. 3Department of Medicine, UCSD, San Diego, California, USA. Microglia are the main resident macrophage population of the CNS and perform numerous functions required for CNS development, homeostasis, immunity, and repair. Many lines of evidence also indicate that dysregulation of microglia contributes to the pathogenesis of neurodegenerative and behavioral diseases. These observations provide a compelling argument to more clearly define the mechanisms that control microglia identity and function in health and disease. In this Review, we present a conceptual framework for how different classes of transcription factors interact to select and activate regulatory elements that control microglia development and their responses to internal and external signals. We then describe functions of specific transcription factors in normal and pathological contexts and conclude with a consideration of open questions to be addressed in the future. Introduction regulatory control necessary to generate cell type–specific programs Microglia are tissue-resident macrophages that perform CNS- of gene expression. This additional information is provided by distal specific functions (1). They derive from a unique lineage of eryth- regulatory elements called enhancers (12). Enhancers represent the romyeloid precursors (EMPs) in the yolk sac and fetal liver (2). most numerous binding sites for LDTFs and signal-dependent tran- EMPs infiltrate the brain during early development, differentiate scription factors (SDTFs), and are major sites for the integration of into microglia, and maintain their population by self-renewal (3). -
Establishment of a Long-Term Stable Β-Cell Line and Its
www.nature.com/scientificreports OPEN Establishment of a long‑term stable β‑cell line and its application to analyze the efect of Gcg expression on insulin secretion Satsuki Miyazaki1, Fumi Tashiro1, Takashi Tsuchiya2, Kazuki Sasaki2,4 & Jun‑ichi Miyazaki3* A pancreatic β‑cell line MIN6 was previously established in our lab from an insulinoma developed in an IT6 transgenic mouse expressing the SV40 T antigen in β‑cells. This cell line has been widely used for in vitro analysis of β‑cell function, but tends to lose the mature β‑cell features, including glucose‑ stimulated insulin secretion (GSIS), in long‑term culture. The aim of this study was to develop a stable β‑cell line that retains the characteristics of mature β‑cells. Considering that mice derived from a cross between C3H and C57BL/6 strains are known to exhibit higher insulin secretory capacity than C57BL/6 mice, an IT6 male mouse of this hybrid background was used to isolate insulinomas, which were independently cultured. After 7 months of continuous culturing, we obtained the MIN6‑CB4 β‑cell line, which stably maintains its GSIS. It has been noted that β‑cell lines express the glucagon (Gcg) gene at certain levels. MIN6‑CB4 cells were utilized to assess the efects of diferential Gcg expression on β‑cell function. Our data show the functional importance of Gcg expression and resulting basal activation of the GLP‑1 receptor in β‑cells. MIN6‑CB4 cells can serve as an invaluable tool for studying the regulatory mechanisms of insulin secretion, such as the GLP‑1/cAMP signaling, in β‑cells.
