Coronavirus (COVID-19) Collection
- In patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, excessive inflammatory responses are considered to play a major role in the pathogenesis of severe coronavirus disease-2019 (COVID-19) disease, leading to acute respiratory distress syndrome and multiple-organ failure (Moore and June, 2020). Dysregulated inflammatory profile, defective immune responses and lymphopenia have also been identified as important features of severe disease (Del Valle et al., 2020; Bordoni et al., 2020).
- Genetic factors such as the HLA type of patients may play a role in regard to disease severity and clinical outcome of patients with COVID-19. Taking the data deposited in the GISAID database, we made predictions using the IEDB analysis resource (TepiTool) to gauge how variants in the SARS-CoV-2 genome may change peptide binding to the most frequent MHC-class I and -II alleles in Africa, Asia and Europe. We caracterized how a single mutation in the wildtype sequence of of SARS-CoV-2 could influence the peptide binding of SARS-CoV-2 variants to MHC class II, but not to MHC class I alleles.
- As of May 17th 2020, the novel coronavirus disease 2019 (COVID-19) pandemic has caused 307,395 deaths worldwide, out of 3,917,366 cases reported to the World Health Organization. No specific treatments for reducing mortality or morbidity are yet available. Deaths from COVID-19 will continue to rise globally until effective and appropriate treatments and/or vaccines are found. In search of effective treatments, the global medical, scientific, pharma and funding communities have rapidly initiated over 500 COVID-19 clinical trials on a range of antiviral drug regimens and repurposed drugs in various combinations.
