A project by NANBIOSIS researchers, focused on COVID-19 detection and therapy, selected in ‘La Marató’ research program

The Scientific Commission of ‘La Marató TV3’ has seleced the project entitled “Diagnosis and treatment of Sars-Cov-2 by triplex formation”, led by Ramon Eritja, Scientific Director of NANBIOSIS Unit 29 Oligonucleotide Synthesis Platform (OSP) from CIBER-BBN and IQAC_CSIC to be financed with € 398,750.00. Verónica Noé from the Fundació Bosch i Gimpera Universitat de Barcelona, ​​the CIBERESP researcher Enrique Calderón Sandubete, from the Virgen del Rocío University Hospital and María Valeria Grazú Bonavía, from the Institute of Nanoscience and Materials of Aragón, INMA (CSIC- UNIZE) also participate in this project.

The edition of this solidarity initiative promoted by the Corporació Catalana de Mitjans Audiovisuals, raised more than twelve million euros to finance research against COVID-19. The project was selected, among the 229 submitted, to receive funding for its development.
Our project wants to solve two important problems in the fight against the COVID-19 pandemic: the first is how to quickly and specifically detect people infected by this virus; and the second is that right now we do not have a effective therapy specifically designed to be used against the virus that causes COVID-19 “explains Dr. Eritja.

The project will try to solve both problems using synthetic oligonucleotides with high and specific affinity for viral RNA. “In recent years, a dozen oligonucleotides have been approved by Health agencies (EMA and FDA) for the treatment of genetic diseases such as Duchene muscular dystrophy as well as metabolic diseases such as familial hypercholesterolemia. In the project we will use specific oligonucleotides, procuced at NANBIOSIS U29, to bind viral RNA that could be used in vitro for the selective capture and diagnosis of the SARS-.COV-2 virus, but also in vivo to inhibit the replication of viral RNA “adds Ramón Eritja.

The call for grants from ‘La Marató’ was carried out, exceptionally, between the months of December and January. Until May, the 229 candidate projects have been reviewed electronically, following a process of proven rigor and transparency, coordinated by the Catalan Agency for Quality and Health Evaluation, in which 95 international evaluators have participated. The assessment, among other aspects, of the quality, the methodology, the scientific, health and social relevance, the innovative value and the viability of the candidate works has determined which projects have been financed with the resources of La Marató 2020.

With this new edition from La Marató, the solidarity project of the Catalan Audiovisual Media Corporation and the Foundation since 1992 an amount of € 216 million have been awarded and a total of 949 research projects hve been promoted, with participation of 9,350 researchers have participated.

New COVID-19 Diagnostic System Ready for Trials in Clinical Samples

The new system for the rapid, economic and efficient diagnosis of COVID-19 devised by the Universitat Politècnica de València (UPV), the IIS La Fe and the CIBER-BBN is now ready for trials on clinical samples. Since the pandemic broke out, the group of Professor Ramón Martínez Máñez, a researcher at the IDM Institute of the UPV and scientific director of the CIBER-BBN and NANBIOSIS U26 RNM for Biomedical Applications I, has been working on an alternative for the diagnosis of COVID-19, based on nanoporous films. These materials are capable of storing an indicator that is released only in the presence of the SARS-CoV-2 virus thanks to a system of molecular gates. And they do it very quickly, reliably and easily.

The material has already demonstrated its ability to detect the Spike protein present in SARS-CoV-2 and also its function for the detection of a model virus that expresses the aforementioned protein and that has been implemented by the Viral Biology group of the I2SysBio, center mixed of the University of Valencia and the Higher Council for Scientific Research (CSIC), led by Dr. Ron Geller.

“These advances represent another step towards obtaining the final device and confirming that the system is capable of recognizing virus particles”, highlights Ramón Martínez Máñez, director of NANBIOSIS U26 NMR for Biomedical Applications I.

The UPV team of researchers will carry out the clinical validation of the device in collaboration with Dr. Javier Pemán and Dr. Mª Ángeles Tormo, from the Serious Infection Research Group at IIS La Fe, by Dr. María Dolores Gómez, Head of the Molecular Microbiology Unit of the Microbiology Service of the Hospital Universitari i Politècnic La Fe and by Drs. Miguel Salavert and Eva Calabuig, of the Infectious Diseases Unit of the aforementioned hospital.

Once its sensitivity for the diagnosis of COVID-19 has been verified, it is planned to develop a final kit and obtain the CE marking, which will allow its commercialization. “We hope that this process will be carried out as quickly as possible and that it may be on the market to provide a new tool in the face of the pandemic that we are suffering,” says Dr. Elena Aznar, a researcher at CIBER-BBN.

Among the advantages of the device devised by the researchers of the UPV, UV, CSIC, IIS La Fe and CIBER-BBN, I would highlight its ease of use, being able to be used for the diagnosis of COVID-19 in places with limited infrastructure. Furthermore, it does not require highly qualified personnel and the sample does not have to be analyzed in specialized laboratories.

“In addition, the POC technologies on which it is based are global detection tools to monitor for possible new outbreaks in the future, so that once it is ready for use, it will contribute to the rapid implementation of containment measures”, he highlights Ramón Martínez Máñez.

The development of this project is financed by funds from the Covid-19 Donations of the Generalitat Valenciana, made by people and companies during 2020 to contribute to the fight against the pandemic. The solidarity of the Valencian citizenship materialized in donations of about 1 million euros, destined entirely to research projects of excellence against the virus such as the one led by Professor Martínez Máñez, managed by the Ministry of Innovation, Universities, Science and Society Digital.

The project also has the support of the Supera COVID-19 Fund, promoted by Crue Universidades Españolas, Banco Santander -through Santander Universidades- and the CSIC. In addition, the I2SysBio Viral Biology group (UV-CSIC) received funding from the Valencian Innovation Agency (AVI) for the implementation of the model virus.

The report by Spanish Higher Council for Scientific Research (CSIC) summarizng the most relevant scientific results on the Covid-19 pandemic.  “A global vision of the Covid-19 pandemic: What we know and what we are investigating from CSIC”, has just published its version number 4.

This report is structured in five blocks: prevention, disease, containment and diagnosis, treatment and vaccines, and global impact.

The containment and diagnosis block describes how the virus is transmitted in the air indoors and the analysis of wastewater as a system for early detection of SARS-CoV-2 is explained. In addition, the importance of diagnosis in the face of the pandemic is underlined and the different types of detection tests available and the diagnostic strategies to control the spread of the infection are detailed. The CIBER-BBN/IQAC-CSIC Nb4D research group and its research platform NANBIOSIS-ICTS Unit 2 Custom Antibody Service (CAbS) takes and important role in this block.

Pilar Marco, Scientific Director of CAbS is co-author, toguether with Cesar Fernandez (IBM-CNM-CSIC) of the chapter 3.4 “The role of the Diagnosis in the face of pandemic” wich provides information on the types of tests, how to perform and how to use them for the different purposes for which  diagnosis is an indispensable tool. “From a broad perspective, we can  distinguish between two types of tests: A. Viral tests: they detect the SARS-CoV-2 virus, include the well-known PCR (Polymerase Chain Reaction) or molecular tests, which detect the genetic material virus B. Test that detect the response of the human body to infection. They include so-called “serological tests, which detect antibodies produced by the patient’s immune system, although other types of biomarkers can also be detected.”

COVID-19 detection system: a fast, cheap and easy to use alternative to PCR.

PCR (acronym in English for “Polymeric Chain Reaction”), is a type of diagnostic test for the detection of infectious diseases. The PCR diagnosis of COVID-19 used since the outbreak of the pandemic offers a high level of specificity and sensitivity but presents a certain degree of complexity, requiring specialized personnel and is expensive.

Researchers from Polytechnic University of Valencia (UPV), the Foundation for the Promotion of Health and Biomedical Research of the Valencian Community (FISABIO), the La Fe Health Research Institute (IIS La Fe) and the consortium Centro de Investigación Biomédica en Red de Bioengineering, Biomateriales y Nanomedicina (CIBER-BBN) has been working, during the pandemic. Within the framework of the Diacovid project, different tests have been carried out with a first prototype of a rapid point-of-care (POC) test, based on nanosystems with molecular gates, that would detect quickly, reliably and easily, SARS-CoV-2.

Ramón Martínez Máñez, Scientific Director of Nanbiosis U26 NMR: Biomedical Applications II explains the advantages of POC techniques as their ability to diagnose in sites with limited infrastructure, without specially qualified staf and without the requirement to transport the sample to a centralized facility. In addition, POC technologies are global detection tools for surveillance against possible new outbreaks in the future. Its use would allow the rapid implementation of containment measures, reduction of therapeutic response times, in situ detection and the use of a low sample volume.

New project to alleviate the effects of Covid will be developed by JUMISC, partner of NANBIOSIS

The Jesús Usón Minimally Invasive Surgery Center (JUMISC), partner of NANBIOSIS, will develop an R&D project aimed at alleviating the effects of the health and social crisis of COVID-19, thanks to a collaboration agreement with Banco Santander.

The project “Analysis of ligands for SARS-CoV-2 in lymphocyte subpopulations with application for disease staging and patient stratification“, will be developed for a year with the collaboration of researchers from from the San Pedro de Alcántara Hospital in Cáceres, the University of Extremadura, the Reina Sofía Hospital and Mount Sinai in New York.

This research initiative aims to provide a reliable prediction of the development of the disease through the study of certain molecules related to the mechanisms of entry of the virus and how they are altered depending on the age and immune status of the individual. The result of the characterization of SARS-CoV-2 receptors and their correlation with the degree of differentiation of lymphocytes of patients could allow, by means of cytometric analysis, the stratification of patients.The project includes three phases: the first will define a panel of antibodies to identify, by cytometry, those subcellular populations with high levels of expression of ligands for the virus; in the second, the panel of markers already defined will be analyzed and the third will allow to establish groups of patients according to the stage of the disease and predict the evolution of those diagnosed.
