Study shows plasmacytoid dendritic cells may be a viable target for protection against SARS-CoV-2

A recent research paper by scientists from Denmark reveals that circulating plasmacytoid dendritic cells may be a potential therapeutic target to maintain desired levels of an antiviral compound known as interferon, allowing for the mitigation of coronavirus disease (COVID-19) severity. The study is currently available on the bioRxiv* preprint server while it undergoes peer review.
