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.

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.

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.

In the "zukunft.niedersachsen"" program, Cluster 2 ""Digital Teaching Hub Lower Saxony"" was funded in the funding line Hochschule.digital Niedersachsen: Pillar B - Studies and Teaching. The TiHo is involved in two sub-projects in this cluster. These are the sub-project ""Cooperation of services in the field of digital teaching (Media didactics)"" and ""AI in studies, teaching and examinations""."

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).

Project Details:
Gaining knowledge about the anatomy and physiology of the forestomaches of ruminants is an important part of veterinary education. This sets the basis for proper diagnosis of diseases and surgical interventions on this organ system in their future professional practice. During their preclinical study part at the University of Veterinary Medicine Hannover, Foundation (TiHo), all veterinary students attend certain anatomical and physiological practical courses related to this topic. These courses also include the work with living animals, hence defined as animal experiments. However, the goal of thorough and sustainable veterinary training, conflicts with the raising legal and public pressure to reduce the number of animal experiments and desired improvement of animal welfare. This project aims to develop a virtual anatomical model of the ruminant forestomaches to be implemented into the Virtual Learning Lab of the Clinical Skills Lab (CSL). This virtual resource can be accessed by all students online at any time, providing flexible learning opportunities. According to the 2022 teaching report, students rated the opportunities for deepening their knowledge at the CSL very positively and expressed a desire for additional offerings that allow for independent and needs-based learning of practical, job-relevant skills. Therefore, a second aim of this project is the development of a malleable 3D model of the rumen, simulating its motility and allows for manual palpation of the organ. Simulations play an important role in medical education and are assessed as very useful by the students when linked to practical relevance. The planned project ranges within the framework of the 3Rs concept for animal experiments providing both, a refinement and a reduction method. Using the simulator, students can learn how to palpate the rumen before they do it on a living animal during the practical course. This helps to reduce anxiety and leads to a more skilled and animal-friendly handling. The virtual forestomach model offers the opportunity for independent preparatory learning and thus contributes to reduce the number of animals used in the anatomical practical courses. During the clinical study phase, both models can be used for repetition of anatomical and physiological basics to support final exam preparation and the acquisition of clinical and surgical skills. Therefore, both models can be used across semesters, promoting the development of learning- and career-related skills and competences.
