Internet Explorer). Huang, C. et al. Zhou et al.1 from the Wuhan Institute of Virology showed, in early February 2020, that the ability of SARS-CoV-2 to infect cells in vitro was dependent on the expression of ACE2, the cell-surface molecule that had previously been shown to be the receptor forSARS-CoV (ref.2). The authors predicted that this lack of interferon responses would enable sustained viral replication and lead to serious SARS-CoV-2 infection. Here, we take readers through the timeline of key discoveries during the first year of the pandemic, which showcases the extraordinary leaps in our understanding of theimmune response to SARS-CoV-2 and highlights gaps in our knowledge as well as areas for future investigations. viral load infectious exposure.
