Researchers identify a new entryway into cells for virus causing COVID-19

Posted on Wednesday, December 7, 2022

Dr. Marceline Côté’s team found a new viral entry for SARS-CoV-2 and suggests it may be able to use proteins to infect a wider range of cells.

One of the many pressing research undertakings by the scientific community amid the ongoing COVID-19 pandemic has focused on ways the coronavirus manages to enter host cells.

Now, in a study adding to the pool of knowledge about viral entry Dr. Marceline Côté’s Faculty of Medicine lab and collaborators have published a highly compelling study showing a previously unrecognized entryway for SARS-CoV-2, the virus that causes COVID-19 and the driver of the global health crisis that’s transformed the world.

Previous studies have shown that SARS-CoV-2 as well as an earlier coronavirus, SARS-CoV-1, the virus behind the SARS outbreak in 2003, enter cells via two distinct pathways. The new research led by Dr. Côté’s lab shows a third entry route.
