Dr Cornelia Blume
Dr Cornelia Blume’s research is focused on understanding the complex interaction of the epithelial barrier with environmental challenges like pollen, viruses and bacteria.
Cornelia is investigating cellular crosstalk regulating inflammation by combining novel 3D in vitro models with state-of-the-art, high-resolution analytical methods in the fields of proteomics, transcriptomics, lipidomics and imaging. She investigates the role of the lipid membrane in coordinating epithelial barrier functions, in particular the anti-viral defence mechanisms in the respiratory epithelium. Cornelia is also leading research to characterise the function of the newly discovered short isoform of ACE2 in the antiviral response.

Discovery of a new, short isoform of ACE2. ACE2 has been shown to bind the Spike protein of the coronavirus SARS-CoV-2 and facilitate virus entry into cells. Early data suggested that ACE2 is induced by type I interferons which raised concerns about the inhaled IFN-beta therapy for COVID-19. We showed that only the new, short ACE2 isoform is induced by IFNs, not the long form which facilitates virus entry. Our data increase the confidence in the safety of inhaled IFN-beta therapy.
