Applications for Viral Pneumonia Including COVID-19

Three consecutive papers with a concise “Perspectives” piece summarizing the reports were published in the August 7, 2020 issue of Science magazine.  The work sheds new light on the importance of Type I (IFN-α & IFN-β) and Type III (IFN-λ or IL-29) interferons for viral pneumonia including severe COVID-19 disease.

Myriad RBM has ultrasensitive immunoassays for all of these proteins available from our CLIA-certified laboratory.

The first two papers (Broggi et al. & Major et al.) describe the mechanisms by which IFN-λ responses contribute to pathogenesis in viral pneumonias and the third paper (Hadjab et al.) shows that critical COVID-19 patients have reduced IFN responses paired with a proinflammatory response; including the possibility that IFN-α and IFN-β plasma/serum levels are predictive biomarkers for COVID-19 Cytokine Storm.
