Another 5% of patients, found that the sequence of the S1-S2 junction of virus isolates from human patients suggested that they fit the C-end rule, with Arg-Arg-Ala-Arg (RRAR) predicted to form the carboxyl-terminal sequence of the furin-cleaved S1. 2. Viruses enter cells and initiate infection by binding to their cognate cell surface receptors. M. et al., “Activation and proliferation of the isolated microglia by colony stimulating factor-1 and possible involvement of protein kinase C” Brain Research 509:119-124 ( 1990). (2020). In this regard, two papers have identified ACE2 as cell entry receptors for SARS-CoV-2 (Hoffmann et al., 2020, Zhou et al., 2020). The angiotensin-converting enzyme 2 is the receptor required for cellular entry of COVID-19, consistent with the epidemiologic risk for severe disease seen in patients with cardiovascular disease and hypertension in China.
