The SARS-CoV-2 virus may enter and replicate in human cells by exploiting newly-identified sequences within cell receptors, according to work from two teams of scientists. The findings from both groups paint a more complete portrait of the various cellular processes that SARS-CoV-2 targets to not only enter cells, but to then multiply and spread. The results also hint that the sequences could potentially serve as targets for new therapies for patients with COVID-19, although validation in cells and animal models is needed. Scientists know that SARS-CoV-2 binds the ACE2 receptor on the surface of human cells, after which it enters the cell through a process known as endocytosis. Research has suggested that the virus may hijack or interfere with other processes such as cellular housekeeping (autophagy) by targeting other receptors called integrins. However, not much is known about exactly how the virus takes advantage of integrins on the biochemical level. Analyzing the Eukar
