Ontogenic, phenotypic, and functional characterization of XCR1+ dendritic cells leads to a consistent classification of intestinal dendritic cells based on the expression of XCR1 and SIRPα

Martina Becker, Steffen Güttler, Annabell Bachem, Evelyn Hartung, Ahmed Mora, Anika Jäkel, Andreas Hutloff, Volker Henn, Hans Werner Mages, Stephanie Gurka & Richard Kroczek
In the past, lack of lineage markers confounded the classification of dendritic cells (DC) in the intestine and impeded a full understanding of their location and function. We have recently shown that the chemokine receptor XCR1 is a lineage marker for cross-presenting DC in the spleen. Now, we provide evidence that intestinal XCR1+ DC largely, but not fully, overlap with CD103+ CD11b− DC, the hypothesized correlate of “cross-presenting DC” in the intestine, and are selectively...

Background: In all European countries, hospital-acquired infections caused by Gram-negative multidrug-resistant microorganisms (GN-MDRO) are a major health threat, as these pathogens cannot be adequately treated anymore, or the start of effective antibiotic treatment is delayed. The efforts to limit the selection and spread of GN-MDRO remains a problem in cross-border healthcare, as the national guidelines on hygiene standards applicable for patients colonized or infected with GN-MDRO in hospitals are not harmonized between European countries. Methods:...

Background: There is a growing body of evidence on the risks and benefits of influenza vaccination in various target groups. Systematic reviews are of particular importance for policy decisions. However, their methodological quality can vary considerably. Objectives: To investigate the methodological quality of systematic reviews on influenza vaccination (efficacy, effectiveness, safety) and to identify influencing factors. Methods: A systematic literature search on systematic reviews on influenza vaccination was performed, using MEDLINE, EMBASE and three additional...

Activation of the Mitochondrial Apoptotic Signaling Platform during Rubella Virus Infection

Claudia Claus, Lena Manssen, Denise Hübner, Sarah Roßmark, Viktoria Bothe, Alice Petzold, Claudia Große, Mareen Reins, Annette Mankertz, Teryl K. Frey & Uwe G. Liebert
Mitochondria- as well as p53-based signaling pathways are central for the execution of the intrinsic apoptotic cascade. Their contribution to rubella virus (RV)-induced apoptosis was addressed through time-specific evaluation of characteristic parameters such as permeabilization of the mitochondrial membrane and subsequent release of the pro-apoptotic proteins apoptosis-inducing factor (AIF) and cytochrome c from mitochondria. Additionally, expression and localization pattern of p53 and selected members of the multifunctional and stress-inducible cyclophilin family were examined. The application...

Characterization of attaching and effacing Escherichia coli (AEEC) isolated from pigs and sheep

Erik Fröhlicher, Gladys Krause, Claudio Zweifel, Lothar Beutin & Roger Stephan
Background: Attaching and effacing Escherichia coli (AEEC) are characterized by their ability to cause attaching-and-effacing (A/E) lesions in the gut mucosa of human and animal hosts leading to diarrhoea. The genetic determinants for the production of A/E lesions are located on the locus of enterocyte effacement (LEE), a pathogenicity island that also contains the genes encoding intimin (eae). This study reports data on the occurrence of eae positive E. coli carried by healthy pigs and...

Knockdown of porcine endogenous retrovirus (PERV) expression by PERV-specific shRNA in transgenic pigs

Britta Dieckhoff, Björn Petersen, Wilfried A. Kues, Reinhard Kurth, Heiner Niemann & Joachim Denner
Background: Xenotransplantation using porcine cells, tissues or organs may be associated with the transmission of porcine endogenous retroviruses (PERVs). More than 50 viral copies have been identified in the pig genome and three different subtypes of PERV were released from pig cells, two of them were able to infect human cells in vitro. RNA interference is a promising option to inhibit PERV transmission. Methods: We recently selected an efficient si (small interfering) RNA corresponding to...

Highly sensitive detection of the group A Rotavirus using Apolipoprotein H-coated ELISA plates compared to quantitative real-time PCR

Cornelia Adlhoch, Marco Kaiser, Marina Hoehne, Andreas Mas Marques, Ilias Stefas, Francisco Veas & Heinz Ellerbrok
Background: The principle of a capture ELISA is binding of specific capture antibodies (polyclonal or monoclonal) to the surface of a suitable 96 well plate. These immobilized antibodies are capable of specifically binding a virus present in a clinical sample. Subsequently, the captured virus is detected using a specific detection antibody. The drawback of this method is that a capture ELISA can only function for a single virus captured by the primary antibody. Human Apolipoprotein...

Methods: Over 12 months, job-seekers were recruited at three job-agencies in northeastern Germany. Among all individuals eligible for study inclusion, 7,906 (79.8%) provided information on smoking, risky drinking, overweight/ obesity (body mass index), fruit and vegetable intake, physical inactivity, illicit drug use, and self-rated health. Proportions and 95% confidence intervals stratified...

Umweltstress, Sozialstatus und Verhaltensauffälligkeiten bei Kindern und Jugendlichen im KiGGS

Dieter Helm & Detlef Laußmann
One aspect of the German Health Interview and Examination Survey for Children and Adole-scents (KiGGS 2003-2006, Principal publication 2007) was to investigate the relationship between social status and health. Socio-economic status, often expressed as an index (e.g. Ducan’s SEI or Winkler’s Index), is known to correlate with health outcomes like behavioural problems. We constructed a new index that en-capsulated not only economic and social but also environmental stressors (ESES), using data of the German Health...

The mglA gene and its flanking regions in Brucella: The role of mglA in tolerance to hostile environments, Fe-metabolism and in vivo persistence

Jens Jacob, Antje Finke & Martin Mielke
We previously demonstrated that a spontaneous smooth small-colony variant of Brucella abortus S19 is characterized by increased in vivo persistence and the differential expression of a gene predicted to encode a galactoside transport ATP binding protein (mglA). In order to further investigate the role of this gene in the context of its flanking regions, we analyzed the respective DNA sequences from the formerly described B. abortus S19 as well as from avirulent B. neotomae 5K33...

Sexual behavior and factors associated with young age at first intercourse and HPV vaccine uptake among young women in Germany: implications for HPV vaccination policies

Cornelius Remschmidt, Michaela Fesenfeld, Andreas M. Kaufmann & Yvonne Deleré
Background: In Germany, immunization against human papillomaviruses (HPV) is free of charge for all females aged 12 to 17 years. Since HPV infection rates rise soon after first intercourse, immunization against HPV should be completed before sexual debut. Knowledge of country-specific data on age at first intercourse and related risk factors is important to optimize prevention of HPV and other sexually transmitted infections. Therefore, the primary aim of this study was to describe sexual behavior...

Survey of pediatricians in Germany reveals important challenges for possible implementation of meningococcal B vaccination

Anja Takla, Ole Wichmann, Judith Koch, Martin Terhardt & Wiebke Hellenbrand
Incidence of invasive meningococcal disease is low in Germany at 0.5 cases/100,000 inhabitants. Serogroup B (MenB) is most common, causing 70% of cases, with highest incidence in infants (5.9/100,000). In 2013, a MenB vaccine was licensed in Europe. To assess pediatricians’ attitudes towards MenB vaccination and its potential use in Germany we conducted a nationwide cross-sectional survey among 5677 pediatricians. Of 3107 participants (response: 55%), 79.1% would recommend a MenB vaccination to parents, with 66.7%...

Gene expression profiling of rubella virus infected primary endothelial cells of fetal and adult origin

Henriette Geyer, Michael Bauer, Jennifer Neumann, Amy Lüdde, Paul Rennert, Nicole Friedrich, Claudia Claus, Ludmilla Perelygina & Annette Mankertz
Background: Rubella virus (RV) infection is usually a mild illness in children and adults. However, maternal infection during the first trimester of pregnancy can lead to congenital rubella syndrome (CRS) in the infant. Fetuses with CRS show damage to the endothelium of the heart and blood vessels; thus, it has been speculated that the clinical manifestations associated with CRS may be a result of endothelial cells persistently infected with RV. Here, we compared the effects...
