In this webinar, you will see:
- Use of MILLIPLEX® Human Cytokine/Chemokine/Growth Factor Panel A to simultaneously profile 48 immune factors in COVID-19 plasma samples.
- How analyte plasma profiles correlated with COVID-19 disease parameters, including the need for mechanical ventilation.
- How a type 2 immune response, specifically IL-13, may play a role in COVID-19 severity.
SARS-CoV-2 is currently causing the global COVID-19 pandemic and understanding the mechanisms that contribute to disease severity will help to protect against poor outcomes. In a previous on-demand webinar, we showed how the MILLIPLEX® SARS-CoV-2 Antigen Panels can be used to test immunoglobulin antibody levels to predict the severity and time point of disease.
Here, we turn our attention to cytokines and report that increased interleukin-13 (IL-13) was associated with the need for mechanical ventilation in two independent patient cohorts. In addition, patients who acquired COVID-19 while prescribed the IL-13 and IL-4 receptor blocker dupilumab had less severe disease. In SARS-CoV-2-infected mice, IL-13 neutralization resulted in reduced disease severity, demonstrating a pathogenic role for this cytokine.
Following IL-13 blockade, Has1, the gene for hyaluronan synthase 1, was identified as the most highly downregulated gene. Furthermore, blocking of CD44, the hyaluronan receptor, reduced mortality in infected mice, suggesting that this pathway is regulated by IL-13. Understanding the role of IL-13 and hyaluronan has important implications for possible therapies for COVID-19 and, potentially, other pulmonary diseases.
