This project focuses on the identification and characterization of glycosylated helminth ligands (protein/lipid) of host C-type lectin receptors (CLRs), in particular Dectin-1, Dectin-2, CLEC12A and DC-SIGN. Further, we plan to investigate how the respective CLR/ligand interactions affect innate responses of host immune cells.

The FBF funded project "Influence of stress during rearing management and later eligibility in sperm production" revealed a clear difference in a developed management score and in mean testosterone concentrations between young bulls with good versus poor sperm quality. However, due to a lack of sensitivity, hormone measurements could not be used as adequate diagnostic tests to identify very good or bad bulls with regard to their later performance and performance persistence, neither at an age of four months nor later at the first semen collection.
This more in-depth study is designed to search for better biomarkers using proteomics as non-target approach. Bulls with a very good versus bad performance persistence over two years will be analyzed by mass spectrometry using the plasma samples collected close to the first semen collection during the preliminary project. Data sets of the mass spectrometric measurements with identified peptides will be matched with a bovine protein database to finally name proteins of the plasma samples. Both groups of bulls will be compared with respect to the proteins identified and the amounts of the same.
In order to establish test methods that are as practicable as possible, promising fertility-associated proteins will subsequently be measured in the blood samples from all age classes investigated during bull calf rearing using commercially available ELISA kits. These data will be used to establish reference ranges and thresholds using receiver operating characteristic (ROC) analyses. Optimally, suitable biomarkers in the blood allow an early preselection of bull calves that are eligible for the collection of quantitatively and qualitatively good semen.

Project Details:
Tetraspanins are evolutionary conserved integral membrane proteins of 200-350 amino acid lengths. Through their large extracellular loop they mediate protein - protein and protein - lipid interactions in cellular membranes thereby shaping membrane microdomains called ?tetraspanin webs?. In humans and mice 33 tetraspanins are described and mosquito species express at least 15 tetraspanin orthologs. In mammalian cells, tetraspanins are host co-factors for several viruses including papillomaviruses, influenza virus, hepatitis C virus, HIV-1 and coronaviruses (Gerold et al., 2015; Bruening et al. 2018; Banse et al., 2018; Alberione et al. 2020; Palor et al., 2020). For hepatitis C virus, colleagues and we showed that the tetraspanin CD81 is a host range determining factor (Vogt et al. 2013; Scull et al., 2015; von Schaewen et al., 2016).
The proposed project aims at characterizing in detail, which of the 33 human tetraspanins in addition to CD81 are host factors for alphaviruses and whether tetraspanins from reservoir species, dead end host species and transmitting mosquito vectors serve as host factors of alphaviruses. Thereby the work will contribute to the understanding of the molecular composition and function of alphavirus replication complexes and determine the role of tetraspanins in species range, transmission and consequently emergence of alphaviruses.

Veterinarians and their employees have a relatively high risk of accidents at work, whether in the clinic, in the diagnostic laboratory or in research. Occupational accident and illness risks in the workplace can be reduced through systematic prevention. Only those who know the specific risks and exposures can minimize them. Safety and health during studies, and later at work in the long term, are the areas that everything should revolve around here. Experience has shown that occupational safety and infection prevention are not the most popular topics and are often only considered relevant once a risk factor has been acutely identified or an accident has already occurred.
The aim of this project is to generate a game-based and collaborative course that uses interactive and digital elements as well as a workshop-based face-to-face event to convey the topic of active occupational safety using memorable practical examples and thus accompany the participants throughout their studies. The aim is to create a profound understanding with long-lasting learning success.

We hypothesize that the stabilization of the vascular system by low-dose ligands to activate the integrin αvβ3 should have beneficial effects on COVID-19 infected patients. We here investigate the effects of the synthetic ligand cylengitide and 29P for integrin αvβ3 in an animal model of SARS-CoV-2 infected hamsters in which the destruction of the vascular system in association with formation of neutrophil extracellular traps has previously been documented.

The core of the research project is to answer important questions regarding the spatiotemporal impact of restrictions due to the Covid 19 pandemic on the value chain of poultry meat production. Data from primary production, structural analyses as well as data on slaughter findings, reported zoonoses in the German population and restrictions due to the pandemic will be linked to derive significances and correlations. From this, important propositions are generated, which address and evaluate the resilience to massive interventions of the integrated process chains in global world trade.

In particular, the project will demonstrate whether the reduction in reported Campylobacter enteritis in the population during the pandemic was due to changes in the occurrence of the pathogen in primary production, process flows in slaughterhouses, changes in consumer behavior, or other factors. The restrictions of the Covid 19 pandemic are included in the synthesis of the results.
