" We aim to define the clinical characteristics associated with the production and the level of neutralizing antibodies (NAbs) in COVID19 recovered patients. In particular, we will investigate whether the development of a strong and persistent humoral immune response takes place in severely affected, individuals with mild symptoms or asymptomatic individuals. We will also study the study the persistence of NAbs overtime. "

" Thanks to high-throughput sequencing of the strains collected for the diagnosis, we document the viral spread within health care facilities. A better understanding of the virus transmission chains are key to evaluate the efficacy of hygiene measures that were implemented to avoid cross-contamination between patients and health care workers. A secondary objective is the analysis of clinical data related to the patients, in order to search genotypic differences that may possibly explain divergent pathogenic courses. "

" Our solution for SARS-CoV-2 induced disease is to develop small molecules able to disrupt interactions between CoV-2 proteins and human interacting proteins. We anticipate that these molecules will substantially affect CoV-2 virulence and associated lung inflammation. "

" Since SARS-CoV-2 testing began at the CHU of Liège we have been carrying out regular whole genome sequencing (WGS) of COVID-19 samples. At the time of writing we have uploaded 187 viral genomes to https://nextstrain.org/ (almost half of the 393 from Belgium). We have carried out regular WGS to monitor the evolution of viral haplotypes. Where possible we have concentrated on health care workers with the goal of identifying clusters of transmission. This included a cluster of seven individuals who were tested on the Roche cobas® instrument using the SARS-CoV-2 test, all were positive for the ORF1ab assay, but negative for the second E-gene assay. To date we have WGS data from four of these individuals, all share identical viral genomes and a SNP in the E-gene has been identified as the most probable cause of the test failure. This observation highlights the importance of redundancy in SARS-CoV-2 assays, especially as some testing regimes recommend an E-gene assay as a primary...

" Development of specific antigens to allow the detection of circulating antibodies against SARS-CoV-2. Our aim is to contribute to the development of serological tests that could help identifying the people previously infected by SARS-CoV-2 and detect the presence of neutralizing antibodies, which would predict an individual protection against COVID-19. With the help of local renowned companies, we are currently testing various antigens and optimizing their production. "

" The first objectives of our approach was to strongly increase the testing capacity for virus by using protocols that are as effective as possible and above all not very dependent on the external sources of consumables and reagents whose supply is threatened. The ULiege testing platform can analyse more than 3000 samples per day and is member on the National testing platform. "

" Massive infiltration of activated macrophages is associated with the development of a cytokine storm that leads to severe acute respiratory syndrome induced by SARS-CoV-2. Based on our results demonstrating the key role exerted by epigenetic regulation in the activity of macrophages, we propose to study the methyltransferase EZH2 in the pathogenesis induced by SARS-CoV-2. We have also shown that the PD-1 immune checkpoint is responsible for the macrophage anergy induced by the absence of EZH2. The goal of the project is to temper the excessive inflammatory responses associated with macrophages by interfering on the EZH2-PD-1 axis. "

" There is a critical need for therapeutic solutions against SARS-CoV-2. Before implementing innovative treatments in human medicine, a first screening of the antiviral or immunomodulatory activity should be performed by in vitro and in vivo methods. To this aim, we developed in vitro (cell culture) and in vivo (hamsters and mice) models of SARS-CoV-2 infection. We developed an in vitro (cell culture) and in vivo (hamsters and mice) to screen antiviral or immunomodulatory molecules, in partnership with colleagues from the ULiège hospital and the GIGA research center. We also validate the inactivation protocols to facilitate the diagnostic workflow, in partnership with the Federal task force. "
Funding: Currently no funding. We applied to the "Crédits urgents de recherche" call.

" As of today, one of the most promising therapeutic solutions against COVID-19 is the use of convalescent plasma. A subset of the antibodies present in this plasma are able to bind the surface proteins of the virus, chiefly the Spike (attachment) protein, and to neutralize the ability of viral particles to infect permissive cells. Upon request of the Red Cross and ULiège CHU hospital, we developed seroneutralization assays to determine the titers in neutralizing antibodies of convalescent plasma. In collaboration with KU Leuven (Rega) and ITM Antwerp, we just completed an interlaboratory ring test. We screen convalescent plasmas on a routine basis for the Croix Rouge and Rode Kruis. Only plasmas with a titer in neutralizing antibodies above the cut-off value will be used therapeutically. The scarcity of the scientific literature on the subject (only a few studies on the therapeutic use of convalescent plasmas are currently available) make it difficult to fix a cut-off...

" "The purpose of this study is to map the healthcare workers exposure risk in Saint-Pierre University Hospital by combining molecular methods with serological assays. In summary, the short-term objective is threefold: (1) Provide an estimate of the sero-prevalence at baseline among high-risk health care workers (2) Determine prospectively the incidence of new SARS-CoV-2 infections among high-risk health care workers (3) Estimate the healthcare worker exposure to the virus by serological data to help our five partner hospitals in their day-to-day management of the ongoing pandemic The mid-term objectives are: (1) Establish an accurate mapping of the spread of the virus among our population allowing to identify the chain of transmission, (2) Identify predictive immunological markers of susceptibility to infection and disease severity to inform vaccine strategies and, (3) Establish solid diagnosis algorithm that will help adequate lockdown...

" The objective of our project is to describe the nasopharyngeal (NP) microbiota and virome of SARS-CoV-2 infected patients at diagnosis through unbiased nextgeneration sequencing analysis and to correlate microbiota and virome profile with COVID-19 infectious phenotype. At a second stage of our project, provided additional findings are raised, those data will be enriched by NP transcriptome analysis of infected patients, and background genomic determination. Integration of those data and analysis through systems biology approach will enable better understanding of multidirectional host-pathogen interactions. "

" Nous faisons face à une pandémie d'infection COVID-19. Ce virus pathogène est source de complications pulmonaires aggravant fortement le pronostic de nos patients. De nos jours, tant les mécanismes physiopathologiques en cause que les marqueurs de sévérité de l'atteinte restent indéterminés. Il apparaît donc comme urgent de pouvoir identifier des marqueurs diagnostiques, pronostiques et prédictifs pour nos patients. Dans ce contexte, plusieurs voies rapidement explorables nous apparaissent comme critiques. Le but final de cette étude est de contribuer à une prise en charge plus ciblée des patients porteurs d'une infection au SRAS-Cov-2. "

" The Center of Microscopy and Molecular Imaging (CMMI) is currently involved in establishing an accurate SARS-CoV-2 virus distribution topography in the organs and various cells of patients who died in COVID-19 units by providing immunohistochemistry and electron microscopy services (study director Pr. Isabelle Salmon). We have also developed and are currently offering preclinical multimodal quantitative imaging - of lung inflammation - of bacterial population (pathogen or no pathogen) - and of viral infection by isotopic imaging. All these models enable the understanding of pulmonary pathological features caused by SARS-viruses such as CoVID-19. From molecular to humanized animal models, the CMMI provides customized imaging solutions to research projects on Coronavirus The CMMI is also a proud partner of the ULB diagnostic platform set-up in Gosselies to face the epidemic of SARS-CoV2.
