" The project investigates the immune responses to SARS-CoV-2 infection in humans. Cohorts of patients and contacts are recruited and followed-up during several months following infection. Using systems serology and systems biology approaches, the quality and dynamics of antibody and cellular responses are analysed to identify correlates of protection against severe disease and to determine the duration of natural immunity to the virus. The project should provide insight in the host response to SARS-CoV-2 and should help define deconfinement strategies and develop prophylactic and therapeutic interventions against COVID-19. "

" The limited capacity of intensive care unit (ICU) beds and the high mortality of patients requiring ICU care after COVID-19 infection are major problems that urgently require solutions. Early evidence suggests that an individual patient's immune responses to this virus are a key factor in their disease pathogenesis. This response can be further compounded by underlying factors, which for patients at Bordet can be exacerbated by their cancer status. A recent study shows that some cancer patients (particularly lung, blood or metastatic cancer patients) are three times more likely to die from COVID-19 infection. Thus, there is an important need to understand and identify immune biomarker(s) that measure functionality of innate and/or adaptive immunity in the blood with rapid turnaround to provide much needed information for clinical decision making. The anticipated results of this collaborative research project include the identification of...

D-tek s.a
" "Multiplex Immuno-Dot technology for COVID-19 serological investigation The Multiplex serological technology, developed since 1995 in D-tek (www.d-tek.be), is dedicated to the profiling of the human antibody response to different immunogens, in a single test. It has various applications in laboratory diagnostics, as well as medical and pharmaceutical research (companion-diagnostics). The technology finds an obvious application for the COVID-19 serological investigation, as the antibody response to the SARS-CoV-2 infection is known to be complex, with multi-epitope targeting, and needs to be better understood. In a typical test (ongoing development), various recombinant SARS-CoV-2 antigens are coated on a membrane strip at different spot positions. The assay is designed to map, in one single test, any patient antibody recognizing any of these protein structures. The test procedure is a classical enzyme immunoassay that can be processed from 10µl of patient's serum or...

Xpress Biologics
" Xpress Biologics, a Belgian based CDMO, has several strategies to tackle the COVID-19 pandemic which includes: - The development of a serology assay to detect Covid-19 seroconversion in humans based on the manufacturing of 3 specific COVID-19 antigens ( full-length Spike protein, S1 subunit, RBD domain) using Pichia pastoris as expression system - Plasmid DNA manufacturing expertise for the development of anti-COVID DNA vaccines - Recombinant protein or antibody fragments manufacturing expertise for diagnostic and treatment of COVID-19 Xpress Biologics has adapted technological platforms that are available to meet the COVID-19 pandemic challenge. In particular our Molecular Biology solution can rapidly help us develop microbial strains for robust and efficient expression of several type of biologics such as viral antigens, neutralizing antibody fragments and DNA vaccines while through our Upstream Process platform we can rapidly engineer industrial processes for...

ULiège - Royal Academy of Sciences, Letters and Fine Arts of Belgium
"The Centre for Protein Engineering (CIP, ULiège), through its two technological platforms, has been involved in the production of reagents (i.e. proteins) for diagnostic and analyses of SARSCoV-2 infection. In particular, Protein Factory has produced a pure and highly active enzyme (CAS12) for a CRISPR/CAS assay, which, in combination with classical PCR technology allows rapid detection of the virus. Automated screening is currently performed at Robotein for optimal formulation of CAS12. The production of complementary protein reagents for such tests is underway. Furthermore, in a collaborative effort with Dr Arnaud Marchant at Institut d'Immunologie Médicale (ULB), the CIP is involved in the design and production of recombinant SARS-COV-2 antigens towards the development of a platform for high dimensional systems serology analysis of SARS-CoV-2 antibodies."

CER Groupe
" "As Approved Research Centre in life sciences, the CER Groupe was requested several times to participate in the action plan against Coronavirus. Among the actions taken, we can point out : • The setting up of an operational structure, qualified to carry out PCR covid-19 tests to assist local hospitals in the lockdown ending and tracing phase ; • Involvement in a Belgian consortium to develop an ELISA quantitative serological test to supplement the PCR analytical capacity and secure the lockdown ending phase ; • implementation of antibody bioproduction for therapeutic/diagnostic use. Finally, let us point out that all of these actions were possible thanks to the involvement and synergy of the CERg various operating units. - development of an ELISA quantitative serological test : design, production and characterization of antigens; design/validation of the ELISA test; production of ELISA kits - production of antibodies in various species (lamas, hens, rabbits, pigs, goats...

" COVerT Our aim is to delineate more accurately the prevalence of the infection in the pregnant population and study vertical transmission in the cord blood of babies born to mothers with confirmed SARS-CoV-2 infection. Determination of prevalence of SARS-CoV-2 infection in mothers by combined universal screening: presence of antibodies (IgG and IgM or IgA) in their blood and/or a positive RT-PCR in the nasopharyngeal swab. We intend to detect evidence of vertical transmission by the identification of SARS-CoV-2 specific IgM or IgA in cord blood samples. If there is evidence of vertical transmission, the analysis of the consequences depending on infection timing during pregnancy will enable us to guide management more precisely. "

" We recently showed that domestic cats can be spontaneously infected by SARS-CoV-2 and develop transient, yet severe, pneumonia. Similar reports in other countries confirmed the susceptibility of cats, ferrets, lions and tigers to the infection. Dogs can get infected but, apparenlty, subclinically. Beside the importance of these findings for veterinarians and animal health, a series of domestic or wild animal species might constitute a reservoir of SARS-CoV-2 and dramatically complicate the "uncontainment" process. Domestic cats, minks, ferrets, hamsters, dogs, tigers and lions were all shown to be naturally or (for some species) experimentally susceptible to SARS-CoV-2 infection. In addition, cats, minks, ferrets and hamsters were shown to be able to efficiently transmit the virus to in-contact animals. Little is known about the actual host range of the virus. It is critically needed to determine which domestic, peri-domestic (especially rodents) and wild animals can...

" During the Covid-19 crisis, I participated in a multidisciplinary research group (biology, medicine, economy) whose objective was to define a deconfinement strategy taking into account public health and economic requirements. We have published several articles for policy makers (VOX-EU), scientists (Nature medicine) and the general public (The Conversation). "

" Are obstructive diseases risk factors for developing pulmonary complications due to COVID19? We will include all patients followed up at CHU of Liege for COVID19 infection and classify them according to their underlying bronchopulmonary disease. The aim is to evaluate if asthma, severe asthma or chronic obstructive pulmonary diseases represent risk factors for developing pulmonary complications during COVID 19 infection. We want to find out biological or clinical predictors of complications. We also want to evaluate efficacy and safety of inhaled corticosteroids in asthma in case of COVID infection. Biomarkers will be measured at baseline and during follow-up. "

" This project aims at developing soluble anti-SARS-CoV-2 virus immunoglobins (IgM and IgG) detection systems based on calixarene coated silver nanoparticles functionalized with viral antigens. These particles could advantageously replace gold nanoparticles (10x more efficient in light extinction) in Lateral Flow ImmunoAssays and Immunoturbidimetry tests. "
