Bovine Viral Diarrhea/ Mucosal Disease (BVD/ MD) is an economically important notifiable disease of cattle. The causative agent, BVD virus (BVDV), is a plus strand RNA virus of the family Flaviviridae, genus Pestivirus. BVDV is known to enter oronasally and through the respiratory tract, from where it spreads to various organs and tissues. The initial stage of infection is poorly understood. In the context of preliminary work it was shown that non-differentiated polarized respiratory epithelial cells are highly susceptible to apical and basolateral infection with BVDV, but virus release occurs only via the apical side of the cells. Thus, it remains unknown how pestiviruses cross the barrier of the airway epithelium. However, it is well established that BVDV and other pestiviruses have a strong tropism for immune cells. Therefore, an important goal of this project is to explore the pathway by which BVDV crosses the barrier of the respiratory epithelium and spreads from there to immune cells.
In the first part of the project, the infection of airway epithelial cells (tracheal/bronchial epithelial cells) will be investigated. Two cell culture systems established at the Institute of Virology are available for the analysis of end-differentiated cells: Air-liquid-interface (ALI) cultures and precision lung slices (PCLS). Subsequently, cells that have not yet completed differentiation or cells that are in the regeneration phase after epithelial injury will be examined. Finally, we will analyze whether BVDV can overcome the epithelial barrier in a paracellular manner by exploiting leaky junctions between cells. To find out whether the different infection characteristics in the different culture systems and under the various infection conditions depending on the degree of differentiation can be correlated or explained with the presence of the cellular receptor, the expression of the receptor for BVDV, CD46, will be analyzed. For the detection of CD46 a monoclonal antibody is available, which was produced at the Institute of Virology. Another focus will be studies on the infection of macrophages. Co-cultures of macrophages and airway epithelial cells will be established to find out whether macrophage infection can be used to overcome the epithelial barrier.
Other interesting perspectives for future projects include the role of cellular innate immunity for respiratory epithelial infection with BVDV, and viral-viral or viral-bacterial co-infections.

The project is carried out at DIL e.V., Quakenbrück.
The DIL leads the work package that focuses on optimising and up-scaling ultrasound (US). Firstly, an extensive literature review on microbial decontamination by US in food and model systems was conducted. It was found that manothermosonication (MTS), a technology that combines mild thermal treatment, elevated pressure, and sonication, is the most promising approach and a potential alternative to traditional thermal pasteurisation of liquid whole egg. Consequently, the DIL developed an MTS prototype that can be used for experimental work with Salmonella Enteritidis. The results showed that MTS can provide the same level of food safety as conventional pasteurisation but with a lower thermal load, suggesting potential food quality benefits confirmed by work on physico-chemical, functional, and protein properties. In addition, sustainability studies using the life cycle analysis (LCA) methodology revealed a lower energy demand in MTS pasteurisation. As a final part of the project, a computational fluid dynamics simulation will be performed to design industrial MTS treatments for continuous application.

With CLIMAQUA an innovative process for the conversion and recycling of aquaculture side streams to feed based on A. platensis is created, which in turn can be used in aquaculture. The aim is to significantly reduce the high greenhouse gas emissions from aquaculture, especially for feed production, by integrating A. platensis into biomass / feed production. Geographical and site-specific features (temperature, length of daylight, etc.) are taken into account in order to obtain an almost completely digestible algae-based feed for salmon and catfish farming and thereby establish a circulatory system that is economically and ecologically sound. In addition, CLIMAQUA examines climate change-related aspects of aquaculture in two regions of the world: The use of innovative technologies in aquaculture is adapted to the climatic conditions and promotes the implementation of sustainable and local food systems.

Project Details:
The retreat of sea ice and the melting and retreat of tidewater glaciers are particularly visible signs of the changes taking place in the Arctic due to global warming. The deterioration of these two physical features of Arctic marine systems is occurring faster in the northern Barents Sea than elsewhere in the circumpolar Arctic, making the Norwegian High Arctic an indicator of climate change in the Arctic region as a whole. The changes will undoubtedly have profound effects on marine ecosystems in the High Arctic and consequences for endemic Arctic marine mammal species.
The ARK research programme will use a variety of data time series (occurrence, ecology, diet, contaminant levels, health parameters, infectious diseases, trophic interactions, etc.) to quantitatively assess different hypotheses on climate change impacts on Arctic marine mammals: 1) Habitat decline will lead to declines in ice-dependent species, changes in distribution patterns and, in the long term, species extinction. 2) Endemic species will increasingly compete with temperate species, which are expanding their habitats. 3) Exposure to new pathogens and increased levels of pollutants will have a negative impact on endemic species. 4) Atlantification of food webs will negatively impact Arctic species and affect the entire Arctic ecosystem.
Within the ARK project, the Kongsfjord, on the west coast of Spitsbergen, will be used in a case-study approach to investigate changes in the ecosystem, apply physical-biochemical food web models and complex risk analyses to make predictions and provide management information.

Das SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus-Type 2) ist der Erreger von COVID-19. Der bisherige Verlauf der COVID-19 Pandemie hat nachdrücklich gezeigt, dass eine koordinierte Bündelung von interdisziplinären und komplementären Expertisen notwendig ist, um die vielfältigen Aspekte der Biologie, der Pathologie und der Epidemiologie von SARS-CoV-2 zu entschlüsseln und die gewonnenen Erkenntnisse sowohl klinisch für die Behandlung von Patienteninnen und Patienten als auch für die Modellierung von Infektionsverläufen in der Bevölkerung einzusetzen. Um einen solch holistischen Ansatz leisten und umsetzen zu können, bietet das Bundesland Niedersachsen mit seinen international renommierten Wissenschaftsstandorten ideale Voraussetzungen. Das Forschungsnetzwerk COFONI arbeitet am Aufbau eines COVID-19 Forschungsnetzwerkes des Landes Niedersachsen (COFONI)um gebündelt Forschungsvorhaben zur Entwicklung neuer Strategien zur Bekämpfung von COVID-19 zu entwickeln. Hauptfokus der Technologieplattform Tiermodelle ist der Aufbau von Tiermodellen für COVID-19.

Cognitive dysfunction is characteristic to the prodromal stages of Parkinson´s disease, and more generally to synucleinopathies. We test novel therapeutic options for cognitive dysfunction associated with alpha-synuclein pathology. We base our interest on microRNAs (miRNAs) which are small endogenous RNAs, and will test the hypotheses that specific miRNAs that are downregulated in PD brains are associated with cognitive dysfunction and, when delivered into the diseased brain, can form the basis for miRNA replacement therapy.

The aim of the project is to transfer an innovative concept for cold-storage of liquid preserved boar semen into practise. This enables the reduction of antibiotics in the preservation medium and additionally, the optimization of the transport logistics of the semen portions from semen collection centers to the sow farms. The environmental impact resulting from antibiotic use is reduced and possibilities for efficient use of boar semen are tested in practice. Thus, the CoolSperm project particularly promotes sustainability and efficiency in future-oriented pig breeding.

SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus Type 2) is the causative agent of COVID-19. The course of the COVID-19 pandemic so far has emphatically shown that a coordinated bundling of interdisciplinary and complementary expertise is necessary in order to decode the diverse aspects of the biology, pathology and epidemiology of SARS-CoV-2 and to use the knowledge gained clinically for the treatment of patients as well as for modeling the course of infection in the population. In order to be able to provide and implement such a holistic approach, the federal state of Lower Saxony offers ideal conditions with its internationally renowned science locations. We are therefore applying for financial support for collaborative research to set up a COVID-19 research network in the state of Lower Saxony (COFONI).
