However, the paucity of markers for isolation of molecularly defined immunomodulatory cell populations poses a barrier to this field. Here, we show that ATP-binding cassette member B5 (ABCB5) identifies dermal immunoregulatory cells (DIRCs) capable of exerting therapeutic immunoregulatory functions through engagement of programmed cell death 1 (PD-1). Purified Abcb5\(^+\) DIRCs suppressed T cell proliferation, evaded immune rejection, homed to recipient immune tissues, and induced Tregs in vivo. In fully major-histocompatibility-complex-mismatched cardiac allotransplantation models, allogeneic DIRCs significantly prolonged allograft survival. Blockade of DIRC-expressed PD-1 reversed the inhibitory effects of DIRCs on T cell activation, inhibited DIRC-dependent Treg induction, and attenuated DIRC-induced prolongation of cardiac allograft survival, indicating that DIRC immunoregulatory function is mediated, at least in part, through PD-1. Our results identify ABCB5\(^+\) DIRCs as a distinct immunoregulatory cell population and suggest promising roles of this expandable cell subset in cellular immunotherapy.}, language = {en} } @article{KirylukYifuSannaCherchietal.2012, author = {Kiryluk, Krzysztof and Yifu, Li and Sanna-Cherchi, Simone and Rohanizadegan, Mersedeh and Suzuki, Hitoshi and Eitner, Frank and Snyder, Holly J. and Choi, Murim and Hou, Ping and Scolari, Francesco and Izzi, Claudia and Gigante, Maddalena and Gesualdo, Loreto and Savoldi, Silvana and Amoroso, Antonio and Cusi, Daniele and Zamboli, Pasquale and Julian, Bruce A. and Novak, Jan and Wyatt, Robert J. and Mucha, Krzysztof and Perola, Markus and Kristiansson, Kati and Viktorin, Alexander and Magnusson, Patrik K. and Thorleifsson, Gudmar and Thorsteinsdottir, Unnur and Stefansson, Kari and Boland, Anne and Metzger, Marie and Thibaudin, Lise and Wanner, Christoph and Jager, Kitty J. and Goto, Shin and Maixnerova, Dita and Karnib, Hussein H. and Nagy, Judit and Panzer, Ulf and Xie, Jingyuan and Chen, Nan and Tesar, Vladimir and Narita, Ichiei and Berthoux, Francois and Floege, J{\"u}rgen and Stengel, Benedicte and Zhang, Hong and Lifton, Richard P. and Gharavi, Ali G.}, title = {Geographic Differences in Genetic Susceptibility to IgA Nephropathy: GWAS Replication Study and Geospatial Risk Analysis}, series = {PLoS Genetics}, volume = {8}, journal = {PLoS Genetics}, number = {6}, doi = {10.1371/journal.pgen.1002765}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-130195}, pages = {e1002765}, year = {2012}, abstract = {IgA nephropathy (IgAN), major cause of kidney failure worldwide, is common in Asians, moderately prevalent in Europeans, and rare in Africans. It is not known if these differences represent variation in genes, environment, or ascertainment. In a recent GWAS, we localized five IgAN susceptibility loci on Chr.6p21 (HLA-DQB1/DRB1, PSMB9/TAP1, and DPA1/DPB2 loci), Chr.1q32 (CFHR3/R1 locus), and Chr.22q12 (HORMAD2 locus). These IgAN loci are associated with risk of other immune-mediated disorders such as type I diabetes, multiple sclerosis, or inflammatory bowel disease. We tested association of these loci in eight new independent cohorts of Asian, European, and African-American ancestry (N = 4,789), followed by meta-analysis with risk-score modeling in 12 cohorts (N = 10,755) and geospatial analysis in 85 world populations. Four susceptibility loci robustly replicated and all five loci were genome-wide significant in the combined cohort (P = 5x10\(^{-32}\) 3x10\(^{-10}\), with heterogeneity detected only at the PSMB9/TAP1 locus (I\(^{-2}\) = 0.60). Conditional analyses identified two new independent risk alleles within the HLA-DQB1/DRB1 locus, defining multiple risk and protective haplotypes within this interval. We also detected a significant genetic interaction, whereby the odds ratio for the HORMAD2 protective allele was reversed in homozygotes for a CFHR3/R1 deletion (P = 2.5x10\(^{-4}\)). A seven-SNP genetic risk score, which explained 4.7\% of overall IgAN risk, increased sharply with Eastward and Northward distance from Africa (r = 0.30, P = 3x10\(^{-128}\)). This model paralleled the known East-West gradient in disease risk. Moreover, the prediction of a South-North axis was confirmed by registry data showing that the prevalence of IgAN-attributable kidney failure is increased in Northern Europe, similar to multiple sclerosis and type I diabetes. Variation at IgAN susceptibility loci correlates with differences in disease prevalence among world populations. These findings inform genetic, biological, and epidemiological investigations of IgAN and permit cross-comparison with other complex traits that share genetic risk loci and geographic patterns with IgAN.}, language = {en} } @article{BenoitAdelmanReinhardtetal.2016, author = {Benoit, Joshua B. and Adelman, Zach N. and Reinhardt, Klaus and Dolan, Amanda and Poelchau, Monica and Jennings, Emily C. and Szuter, Elise M. and Hagan, Richard W. and Gujar, Hemant and Shukla, Jayendra Nath and Zhu, Fang and Mohan, M. and Nelson, David R. and Rosendale, Andrew J. and Derst, Christian and Resnik, Valentina and Wernig, Sebastian and Menegazzi, Pamela and Wegener, Christian and Peschel, Nicolai and Hendershot, Jacob M. and Blenau, Wolfgang and Predel, Reinhard and Johnston, Paul R. and Ioannidis, Panagiotis and Waterhouse, Robert M. and Nauen, Ralf and Schorn, Corinna and Ott, Mark-Christoph and Maiwald, Frank and Johnston, J.

This global resurgence is likely linked to increased international travel and commerce in addition to widespread insecticide resistance. Analyses of the C. lectularius sequenced genome (650 Mb) and 14,220 predicted protein-coding genes provide a comprehensive representation of genes that are linked to traumatic insemination, a reduced chemosensory repertoire of genes related to obligate hematophagy, host-symbiont interactions, and several mechanisms of insecticide resistance. In addition, we document the presence of multiple putative lateral gene transfer events. Genome sequencing and annotation establish a solid foundation for future research on mechanisms of insecticide resistance, human-bed bug and symbiont-bed bug associations, and unique features of bed bug biology that contribute to the unprecedented success of C. lectularius as a human ectoparasite.}, language = {en} } @article{EckardtStasikKrameretal.2021, author = {Eckardt, Jan-Niklas and Stasik, Sebastian and Kramer, Michael and R{\"o}llig, Christoph and Kr{\"a}mer, Alwin and Scholl, Sebastian and Hochhaus, Andreas and Crysandt, Martina and Br{\"u}mmendorf, Tim H. and Naumann, Ralph and Steffen, Bj{\"o}rn and Kunzmann, Volker and Einsele, Hermann and Schaich, Markus and Burchert, Andreas and Neubauer, Andreas and Sch{\"a}fer-Eckart, Kerstin and Schliemann, Christoph and Krause, Stefan W. and Herbst, Regina and H{\"a}nel, Mathias and Frickhofen, Norbert and Noppeney, Richard and Kaiser, Ulrich and Baldus, Claudia D. and Kaufmann, Martin and R{\´a}cil, Zdenek and Platzbecker, Uwe and Berdel, Wolfgang E. and Mayer, Jiř{\´i} and Serve, Hubert and M{\"u}ller-Tidow, Carsten and Ehninger, Gerhard and St{\"o}lzel, Friedrich and Kroschinsky, Frank and Schetelig, Johannes and Bornh{\"a}user, Martin and Thiede, Christian and Middeke, Jan Moritz}, title = {Loss-of-function mutations of BCOR are an independent marker of adverse outcomes in intensively treated patients with acute myeloid leukemia}, series = {Cancers}, volume = {13}, journal = {Cancers}, number = {9}, issn = {2072-6694}, doi = {10.3390/cancers13092095}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-236735}, year = {2021}, abstract = {Acute myeloid leukemia (AML) is characterized by recurrent genetic events. The BCL6 corepressor (BCOR) and its homolog, the BCL6 corepressor-like 1 (BCORL1), have been reported to be rare but recurrent mutations in AML. Previously, smaller studies have reported conflicting results regarding impacts on outcomes. Here, we retrospectively analyzed a large cohort of 1529 patients with newly diagnosed and intensively treated AML. BCOR and BCORL1 mutations were found in 71 (4.6\%) and 53 patients (3.5\%), respectively. Frequently co-mutated genes were DNTM3A, TET2 and RUNX1. Mutated BCORL1 and loss-of-function mutations of BCOR were significantly more common in the ELN2017 intermediate-risk group. Patients harboring loss-of-function mutations of BCOR had a significantly reduced median event-free survival (HR = 1.464 (95\%-Confidence Interval (CI): 1.005-2.134), p = 0.047), relapse-free survival (HR = 1.904 (95\%-CI: 1.163-3.117), p = 0.01), and trend for reduced overall survival (HR = 1.495 (95\%-CI: 0.990-2.258), p = 0.056) in multivariable analysis. Our study establishes a novel role for loss-of-function mutations of BCOR regarding risk stratification in AML, which may influence treatment allocation.}, language = {en} }
