Resources for coronavirus (COVID-19) research

Scientists around the world are involved in research to better understand the immunopathogenesis of the COVID-19 virus, enabling the development of therapeutic vaccines and treatment modalities to combat this pandemic.

Flow cytometry is a critical tool used by many labs for studies including:

  • Immune cell profiling
  • Cytokines, and T and B cell analysis
  • Detection of cytokine response or cytokines neutralizing antibody titers in patient blood
  • Sorting of antibody-producing B cells for therapeutic antibody candidates

We are committed to supporting the research community in its mission to advance scientific knowledge about the virus, and aim to develop focused solutions during these challenging times.

Navigate the resources below to help with your teams’ COVID-19 research.

Cell sorting and COVID-19 research

There are several crucial clinical questions surrounding COVID-19 that urgently need an answer. Discovering more about the immune system, and which assays, approaches, models and methodologies are best to use, is key in the research to make an impact in the fight against this virus. Deep characterization of the immune system is essential, and an approach that combines flow cytometry and single cell multi-omic profiling may offer some insight into possible solutions, such as developing a cure or an innovative vaccine.

Flow cytometry is an indispensable tool in COVID-19 research. Sony cell sorters are microfluidics-based flow cytometry systems used for high throughput and gentle isolation of COVID-19 donor cells. Purified cells of interest are used for studies ranging from therapeutic monoclonal antibody discovery and immune repertoire analysis to single cell transcriptome analysis for investigating virus pathology.

Rationale for neutralizing antibody discovery for COVID-19 treatment

Donor blood sample is a source of peripheral blood mononuclear cells (PBMCs). Enriched B cells are used for sorting antigen-specific B cells. These are processed for in vitro expansion/activation sequence analysis to identify best candidates. Characterized candidates are then scaled up for therapeutic treatments

Analysis of immune repertoire using flow cytometry

Analyses of innate and adaptive immune responses during acute COVID-19 infection offer information on the underlying basis of the anti-viral activity and inflammatory response, supporting the development of treatments.

The workflow below shows the steps of isolating immune cells of interest by flow-based cell sorting, and the functional assays needed to study immune cell subsets, as well as the types and levels of cytokines produced.

Diagram of single cell workflow

Single cell isolation for transcriptome analysis of COVID-19 infected cells

Transcriptome landscape of blood immune cell subsets are being studied to better understand the immune clearance mechanism in COVID-19 infection. In order to look at the transcriptome, the nuclei need to be extracted from infected tissue. Viable nuclei are then sorted for downstream RNA Seq analysis, before transcriptome analysis of the single cells to understand the tropism of the COVID-19 virus.

Sony solutions

Flow cytometry forms a large part of the global effort to combat COVID-19 and Sony offers a range of instrumentation to help. The MA900 Multi-Application Cell Sorter can isolate and analyze epithelial, dendritic, monocytic and alveolar macrophage populations from infected lungs, providing important information about the immunopathology of COVID-19. The Sony SH800 Cell Sorter can purify nuclei from lung tissue of healthy donors to be isolated to study the epigenetic regulation of key lung genes. These cell sorters are used for isolation of antigen-specific B cells for profiling human antibodies targeting the SARS-CoV-2 spike protein.

The table below shows Sony’s solutions for a range of experimental protocols for investigating COVID-19.

COVID-19 research highlights

Scientists around the world are using Sony’s solutions for their critical COVID-19 research. Below are examples of some of the important collaborative work that is being carried out using Sony cell sorters.

Rapid isolation and profiling of a diverse panel of human monoclonal antibodies targeting the SARS-CoV-2 spike protein

Stylized image of vaccine vial and gloved hand

The novel coronavirus SARS-CoV-2 pandemic has led to millions of infections and hundreds of thousands of deaths, and there is an urgent need to develop therapeutics. A recently published study has isolated hundreds of human monoclonal antibodies (mAbs) against the SARS-CoV-2 spike (S) protein, using the SH800 cell sorter to isolate target-specific memory B cells from pooled PBMCs of two patients with documented infection. The results provide potential candidate biologics, showing that many of these mAbs inhibit virus infection, with most neutralizing mAbs recognizing the S protein receptor-binding domain (RBD). The work also highlights the RBD of SARS-CoV-2 S as a potential target for vaccine design and therapeutic antibody development.

Single nucleus multi-omic profiling reveals age-dynamic regulation of host genes associated with SARS-CoV-2 Infection

Stylized image of human lungs and viruses

As the COVID-19 (SARS-CoV-2) pandemic has engulfed the globe, respiratory failure has emerged as the leading cause of death, with a disproportionate impact on adults compared to children. Learn more about a recently published study, that looked at the expression patterns of a number of genes implicated in SARS-CoV-2 cell entry in lung cell samples from healthy donors of different ages. Using large-scale single nuclei ATAC-Seq/RNA-Seq, it aimed to identify age-associated changes that could help to explain differences in susceptibility and response to SARS-CoV-2 infection.

Type III interferons disrupt the lung epithelial barrier upon viral recognition

Diagram of cytokine

Inflammation and superinfection susceptibility appear to be linked to case severity when it comes to the recent outbreak of the highly pathogenic SARS-CoV-2 pandemic. The ability to overcome lung viral infections relies on the production of interferons (IFNs) and inflammatory cytokines, and researchers have suggested the use of type III IFNs against SARS-CoV-2 to limit immunopathology but maintain antiviral activity. A recently published study looked at the ability of SARS-CoV-2 to induce interferon production in the upper or lower airways, as well as directly evaluating the contribution of IFN-λ to immune pathology.

Vanderbilt vaccine development program sprints towards COVID-19 antibody therapies

Photo of researcher and syring with vial

VVC researchers have developed techniques for rapidly isolating clones of white blood cells that produce antibodies targeting – and neutralizing – specific viral proteins. Using these techniques, they have generated human monoclonal antibodies against a wide range of pathogenic viruses including Ebola, chikungunya, HIV, dengue, norovirus and respiratory syncytial virus (RSV). The team has pioneered the rational design of neutralizing antibody treatments and vaccines, some of which have progressed to clinical trials, and are now hoping to develop antibodies that could be given to people infected with SARS-CoV-2. Learn more about their work here.
