Project Details:
The overall aim of the HELCOM BLUES project is to support regional capacity, coordination and cooperation with regards to developing effective measures to secure good status of the marine environment. This includes provisioning, and making available, necessary knowledge to advance the development and implementation of joint measures addressing common pressures, as well as to provide concrete support to the decision-making process within the Baltic Sea region.
The task carried out by TiHo focuses on highly mobile and under-reported groups (here: cetaceans), and considers several aspects identified in recent HELCOM review processes to be knowledge/assessment gaps and aspects of high regional priority. The harbour porpoise can be categorised as both a highly mobile and an under-reported species in the Baltic Sea region. At present, there are no functional regional HELCOM indicator(s) to assess status for abundance or distribution, which are two of the primary Marine Strategy Framework Directive criteria under MSFD D1. This clear gap was identified as a high priority for the HELCOM region. This task will provide support for the HELCOM indicator team and focus on improving methods and operational assessments of harbour porpoise abundance by HOLAS III, and on harmonising methods of assessment with other EU regions (i.e. OSPAR and HELCOM). The main aspects addressed by TiHo are:
1) Establishment of a harmonised approach to indicator development for harbour porpoises between HELCOM and OSPAR (of particular relevance to shared marine areas);
2) Assessing trend in abundance for assessment of the Belt Sea population;

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).

Project Details:
The viral genome of an RNA virus is released into the cell, where the viral genome is amplified and its transcripts translated into proteins to form more copies the virus. CRISPR/Cas13 enzymes cleave different sites of the viral genome and its transcripts through a combination of crRNAs. Proliferation of the virus is blocked and transcripts to be translated into viral proteins are reduced.

Project Details:
CoVid-19 is characterized by infection of the airways by SARS-CoV-2. Apart from the respiratory tract, other organs are also involved, e.g. the intestinal tract. The importance of the intestinal infection is increasingly recognized. In a large proportion of pediatric patients, virus was detected in rectal swabs and virus shedding from the intestine was found even when oral swabs had become negative. Therefore, prolonged virus shedding and fecal-oral transmission have to be considered. This notion is supported by detection of the virus in wastewater.
The aim of this short project is to apply intestinal cell cultures to characterize the infection of differentiated intestinal epithelial cells by SARS-CoV-2 and thereafter intestinal orgranoids.
This in vitro infection approach will target the following aims:
1. Characterization of the replication efficiency of SARS-CoV-2 (virus yield, virus exit, virus entry, apical, basolateral).
2. Localization of the cellular receptor(s) in human intestinal Caco-2 cells
3. Investigation of the trafficking of the cellular receptor(s), determination and subsequent modulation of their mode of interaction with membrane microdomains (lipid rafts, LRs)
4. Effects of glycosylation modulators on the spike glycoprotein and its interaction with intestinal cells
5. Implication of virus infection on the trafficking and function of crucial enzymes of the intestinal physiology (APN, SI, LPH, DPP4).
This project will provide substantial information on the replication of SARS-CoV-2 in intestinal epithelial cells, evaluate its effects on the intestinal function and provide solid hypotheses on the molecular and biochemical basis for the symptoms elicited by SARS-CoV-2 infections. These hypotheses can be then examined at a later stage in intestinal organoids. Further, unravelling the biosynthetic pathway, glycosylation pattern and mode of interaction of the SARS-CoV-2 receptors and its modulation could constitute exquisite targets for potential therapy.

Vaccination is an important measure in controlling the COVID-19 pandemic. However, there were pharmocovigilance concerns as a very rare but potentially disastrous complication was identified after application with the ChAdOx1 nCoV-19 vaccine, i.e. cerebral sinus thrombosis, but also further thrombotic complications including ischemic stroke. Meanwhile, the most likely mechanism has been identified as platelet factor 4 (PF4) antibody mediated immune thrombotic thrombocytopenia, a mechanism which is already known from heparin-induced thrombocytopenia (HIT). Interestingly NETs were suggested to be critical for thrombus formation in the HIT-pathophysiology as well. Markers of NETosis were observed in platelet-rich thrombi in the lungs of mice with HIT. Therefore, NETs might also be involved in vaccine-induced immune thrombotic thrombocytopenia (VITT) mediated thrombotic complications and might therefore be a common trunk in the pathogenesis of COVID-19 and vaccine-induced complications. Moreover, biomarkers reflecting NETs burden in the circulation and within tissue specimens (e.g. cerebral thrombi) may be suitable as diagnostic, therapeutic or prognostic targets in thrombotic diseases. Most importantly, there is a tremendous need to identify patients at risk for cerebrovascular complications due to both COVID-19 and VITT. The proposed project ISI-VITT is intended to contribute to addressing this issue.

Project Details:
Current antiviral agents mainly target stages in the viral life cycle such as viral attachment to host cell or replication of viral RNA and DNA. Most of the available antiviral agents are effective against replicating viruses only, and due to the lack of specificity, many have adverse side effects. Particularly in endemic and pandemic disease outbreaks, there is additional challenge through virus mutagenesis and the development of viral variants. Therefore, approaches, which target various virus variants are urgently needed. Current paradigms in antiviral treatment involve usage of small molecules and/or therapeutic antibodies. Small molecules often have secondary targets and thus can cause side effects. Antibodies are expensive, their administration is mostly limited to clinical settings, and also they are affected by mutations. In an endemic or pandemic situation, therapies which have broad coverage within virus families, prevent transmission, and can be safely applied during mild and moderate illness are especially valuable.

Our novel approach aims to fill this need through the use of CRISPR/Cas13, an enzyme from bacteria, which cleaves RNA, including the viral genome (of RNA viruses) and of viral mRNA, thereby blocking viral replication and generation of viral proteins. Our therapeutic strategy has no secondary targets, and can be produced at GMP level at low cost. Through a specific combination of so-called crRNAs, Cas13 is directed to different viral mRNAs and to different sites within the viral genome. The crRNAs are selected such that no human RNA is targeted, and therefore no adverse side effects can be expected. This technology can easily be adapted for any single stranded RNA virus. Through targeting different and highly conserved regions, this approach antagonizes also emerging variants of the original virus.
