Project Details:
Motile cilia are microtubule-based, hair-like projections on the luminal membrane of epithelial cells in conducting airways. Through their continuous wave-like beating, they evacuate mucus secreted by goblet cells, thereby contributing to muco-ciliary clearance (MCC). In this function, motile cilia are actors of the first-line defense against inhaled pathogens. Dysregulated cilia will have a long-term effect on MCC and predispose for further diseases. Similarly, the diffuse endocrine system plays an essential role in respiratory tract imbalances. However, underlying pathogenetic mechanisms are not well understood, neither in various organs nor in the trachea and larynx. Therefore, the envisioned study will enhance our understanding of short- and potential long-term effects of SARS-CoV-2 infection in the upper respiratory tract and its associated endocrine and nervous system.

Project Details:
This project aims to investigate the effect of an early (3 days post infection [dpi]) and a late (8 dpi) adoptive transfer of green (GFP) and red fluorescent (RFP) T- cells on the microglial morphology and transcriptomic data in TMEV- infected OT-I and OT-II mice. The contribution of CD8+ and CD4+ T cell subsets for viral clearance and course of clinical disease will be investigated individually as well as the general pathomorphology and immune response with special focus on microglia morphology and transcriptomic data.

Project Details:
It is well known that a number of viral pathogens can be detected in saliva of infected humans and animals. However, for most of these viruses the source of their presence in saliva and in the oral cavity remains unknown. While it has been reported that human salivary glands can be infected by SARS-CoV-2 and some other viruses, the role of salivary gland tissues in infection of pigs with respiratory and most enteric viruses has not been addressed so far. To characterize infection of porcine salivary glands by both respiratory viruses (influenza A virus, porcine respiratory coronavirus) and enteric viruses (transmissible gastroenteritis virus, porcine rotavirus A), differentiated salivary gland epithelial cells and organoid cultures from pigs were established by the group of the PI. In addition to porcine influenza viruses, human and avian influenza viruses will be used to investigate a possible role of porcine salivary glands in interspecies transmission and evolution of influenza virus.

Project Details:
The bovine epithelia-choreal placenta protects the fetus from infections with numerous pathogens. However, some viruses, such as bovine viral diarrhea virus (BVDV) or bluetongue virus, are able to cross the placenta barrier during pregnancy. In the case of BVDV, diaplacental infection with non-cytopathogenic (ncp) viruses between the 40th and 125th day of gestation is a mandatory prerequisite for the establishment of persistent infections and is therefore of outstanding epidemiological importance. In contrast, infection of pregnant animals with cytopathogenic (cp) BVDV does not lead to the birth of persistently infected offspring.
An important aspect of the placenta's barrier function against pathogens is innate immunity. First, we want to investigate the innate immune response of polarized bovine placenta cells to dsRNA applied to either the basolateral or apical compartment. Moreover, we will examine the efficiency of viral replication and release of BVDV and other bovine viruses, and characterize the innate immune response after basolateral and apical infection.

Project Details:
As top predators, marine mammals play a crucial role in the ecosystem, as they regulate and maintain marine food webs, promote the biodiversity of the marine environment and contribute to the overall maintenance of the ecological balance. The protection of their habitats and the conservation of the biodiversity of marine mammals is of great importance and can contribute to the long-term health of the entire marine ecosystem.
Against the background of increasing or shifting populations of marine mammals, lower life expectancy and the increase in anthropogenic activities, threats and conflicts caused by stressors are also increasing, including fishing (bycatch, entanglement, overfishing, habitat degradation), shipping traffic (noise, collisions, pollution), offshore wind energy projects (noise, habitat loss, increasing shipping traffic), raw material extraction, sand and gravel mining and tourism.
Scientifically robust concepts and high-quality data are required to assess the status in order to adopt measures that will subsequently lead to a good conservation status of the respective populations of marine mammal species. To ensure that this data is available as comprehensively, comparably and are-wide as possible regional coordination of monitoring and the indicators used for evaluation is essential.
The aim of this research project is to develop recognized indicators based on reliable data in order to reliably assess the status of marine mammals in the North and Baltic Seas. These indicators are to be defined and coordinated at both regional and national level, which is also stipulated by the Marine Strategy Framework Directive (MSFD). Various approaches for assessing the status of biodiversity within the framework of the MSFD are being developed, improved and harmonized at international, regional and national level. The indicators are used nationally, regionally and internationally in marine conservation agreements (relevant for Germany: Oslo-Paris Commission (OSPAR) and Helsinki Commission (HELCOM)) by numerous committees and working groups (e.g. under the International Council for the Exploration of the Sea (ICES)).
The ITAW plays a leading role in these committees, for example as head of the expert groups and in the development of indicators.
In this way, the project is generating evaluation methods, models, basic knowledge that can be used in the long term, and urgently needed knowledge on options for action, which is required for the implementation of political and social objectives, for example under the (MSFD).
