SARS-CoV-2 immunology: Understanding the interactions between
SARS-CoV-2 and the host immune system
September 15, 2022
We are in a global pandemic. As the COVID-19 pandemic continues to spread worldwide, there is a pressing need to understand the biological mechanisms determining disease progression and severity. Early research studies have reported alterations in the immune cell composition and dysfunctional immune responses in COVID-19 patients. The extent of the immune dysregulation appears to correlate with the severity of COVID-19 disease. A deeper understanding of the interactions between SARS-CoV-2 and the host immune system is required to further understand the pathogenesis of this disease and identify biomarkers that could, potentially, be used to predict, monitor or prevent COVID-19 progression.
Flow cytometry—a critical tool in COVID-19 research
Flow cytometry plays a critical role in the study of COVID-19 immune response due to the ability to simultaneously measure expression of multiple proteins at the single-cell level. Flow cytometry is therefore routinely used to assess immunophenotypic and functional changes (cytokine production, proliferation, cytotoxicity) in response to viral infection. Some of these assays are also used in vaccine research to assess vaccine candidate immunogenicity.
Multicolor flow cytometry panels for COVID-19 research
Design and optimization of multicolor panels can be challenging and time consuming. To help you accelerate your research, we have created a repository of pre-optimized multicolor flow cytometry panels for the identification of immunological changes previously reported in COVID-19 patients. The panels were designed using best practices and to deliver the best performance, defined as the ability to resolve populations of interest. The panels have been tested on non-COVID-19 healthy human blood samples.

BD Dri Chroma Custom Panel
The dried multicolor panels reduce inter-experiment variability and come with long shelf lives making them ideal choices for multisite and longitudinal studies. A wide variety of reagents and dyes are available for cocktailing, including BD Horizon Brilliant™ Dye Reagents. With the introduction of BD Horizon™ Dri Chroma Technology, dried panels can have up to five* BD Horizon Brilliant™ Dyes in a single tube. Dried multicolor cocktails also have an extended shelf life compared to liquid reagents with stability of ≥1 year when stored at room temperature (20–25 °C). In addition, you can easily incorporate these dried down reagents into your assay workflows, which can help with standardization and efficiency.
*For panels containing more than five BD Horizon Brilliant™ Dyes, contact your sales representative to look at options for your panels.
