Project Details:
Die steril-eitrige Meningitis-Arteriitis des Hundes (SRMA)ist die häufigste entzündliche Erkrankung des zentralen Nervensystems des Hundes im Norddeutschen Raum. Mit Hilfe mehrerer Pathogenesestudien soll versucht werden, die Erkrankung besser zu charakterisieren, um neue Therapiestrategien entwickeln zu können. Die Zellpopulation in Liquor cerebrospinalis und Blut wurde mit Hilfe durchflusszytometrischer Studien charakterisiert. Studien zur Zytokinexpression sollen helfen, das Phänomen der hohen IgA Produktion zu erleuchten. Die Untersuchung von Toll-like Rezeptoren soll einen Hinweis auf die Ätiologie der Erkrankung liefern. Die Th17 Antwort, NETs und das Endocannabinoidsystem werden näher untersucht

Project Details:
Few standardized studies are available on the effect of slow-release GnRH agonists in avian patients. With this background, the aim of this study is to examine the influence of deslorelin, a slow-release GnRH agonist, on the gonadal activity of female and male budgerigars in order to optimize the clinical use of this drug. The activity of the gonads will be examined, for example, by determining the sex hormones and by radiographic assessment of the reproductive organs.

Project Details:
The high-energy cosmic radiation has a decisive influence on all manned space missions. The effect of this radiation on the model organism Trichoplax adhaerens (Placozoa) will be investigated in this project. Placozoans are the most simply organized multicellular animals and can give us crucial clues about the effect of cosmic radiation on humans.

Project Details:
The European Partnership on Animal Health and Welfare (EUPAHW) is a research and innovation initiative funded by the European Commission (EC) to control infectious diseases of animals, and to promote animal welfare. Due to the close link between animal health, animal welfare and human well-being, the One Health-One Welfare perspective takes a prominent position in the EUPAHW. Within the EUPAHW, the Institute for Terrestrial and Aquatic Wildlife Research will work with other partners on wildlife-livestock-human interface. The overall objective is to integrate the health of wild mammals and birds into the overall health surveillance and monitoring of livestock. Wildlife health surveillance contributes to the assessment of environmental health because wild animals may serve as sentinels for both terrestrial and aquatic ecosystems. Improving wildlife population monitoring and surveillance of wildlife pathogens/diseases aims to detect the emergence of pathogens and reduce the risk of transmission of infectious diseases between wildlife and livestock and even humans. The information is needed to design, apply and support sustainable livestock and wildlife management systems. In this context, the EUPAHW will assess the impact of climate change and human/anthropogenic activities such as hunting, trade, feeding, rewilding and translocation of wildlife on the spread of diseases and the establishment of invasive species.

Project Details:
We will study the immunogenicity and efficacy of our vaccine candidate, MVA-MERS-S, when used in different single vaccination and vaccination-booster setting in the lethal k18-hDPP4-mouse model after MERS-CoV-challenge infection. Different vaccination schedules also include different time points of challenge infection. We will characterize the activation of MERS-CoV-specific antibodies and T cells. The protective efficacy will be analyzed by morbidity, mortality and viral load in the lung and the brain a target organs. Moreover, a histopathological examination of the upper and lower respiratory tract of the animals upon challenged with MERS-CoV will show any evidence of ADE and ERD, respectively. Another study will evaluate the impact of passively transfered sera from MVA-MERS-S vaccinated mice for the outcome of protection after challenge infection.

Project Details:
Chronic pain represents a significant health problem affecting approximately 20 to 50% of the world's population. Therapeutic methods are largely developed in behavioral tests with induced pain in rodents. This approach does not allow for pain treatment, leading to severe distress for the animals. Nevertheless, therapeutics developed in animals are not always effective in humans. Therefore, two in vitro models using human cells will be developed to quantify neuron-mediated chronic pain with the highest possible predictive power. For this purpose, stem cell-derived sensory neurons will be used (1.) to develop a luciferase-based exocytosis assay to easily quantify the increased release of neuropeptides (Substance P and Calcitonin Gene-Related Peptide) involved in the chronic pain response. Additionally, (2.) an innervated skin model will be developed to quantify neurite outgrowth and the expression of regulated genes associated with chronic pain receptors and ion channels involved in signal transduction in vitro. The proof-of-concept for the use of these models in pharmacology and toxicology will be provided by inhibiting induced neuropeptide release, induced neurite outgrowth, and induced gene expression with therapeutically effective substances or by triggering them through the addition of exogenous substances. This approach allows for the modeling of molecular pathways of chronic pain development in vitro, directly in human cells, to avoid unnecessary animal experiments and to develop effective and safe therapeutics for humans. Following the project, the skin model will be adapted to model atopic dermatitis using induced pluripotent stem cells and primary cells from patients, aiming to bring specific in vitro disease models into application for the development of new therapies in cooperation with industrial partners. Furthermore, the project should serve as a foundation for further cross-disciplinary in vitro modeling, such as the simulation of chronic joint pain.

Project Details:
Amphibians worldwide are confronted with a variety of factors causing a rapid population declines. In Schleswig-Holstein, these population declines can also be in otherwise widely distributed species and cannot be explained by structural parameters alone, such as habitat loss and alteration. Other factors influencing amphibians can include toxicological contamination and invasive pathogens. The effects of those stressors on our native amphibians are largely unknown. Furthermore, the extent to which the different stressors interact is largely unknown, although it is assumed that they potentiate each other. In order to implement successful conservation measures in the long term, it is important to identify and evaluate the relevant stressors. Based on preliminary studies carried out at the Institute for Terrestrial and Aquatic Wildlife Research (ITAW) from 2021 to 2023, the project aims to investigate possible stressors for amphibians native to Schleswig-Holstein. This includes the continued monitoring of pathogens, such as fungi originating from Asia (Batrachochytrium dendrobatidis (Bd) and B. salamandrivorans (Bsal)) as well as Ranaviruses and herpes viruses. In addition, of animal-related data as well as data on habitat-specific factors are collected to be able to explain differences in the occurrence of infectious agents. The collection of habitat-related data includes water quality characteristics (e.g. pH value, water temperature) and analyses of possible contaminants correlation with utilization, structure and surrounding vegetation over the course of the year.
In addition to recording possible stressors and their interaction, this study aims to develop a basis to evaluate habitats in the course of species protection measures such as reintroduction projects.
