Without a receptor, there is no replication. Without replication, there is no infection. Researchers in Princeton University’s Department of Chemistry and the Department of Molecular Biology have used a cellular mapping technology called µMap, introduced just two years ago by the MacMillan Lab, to uncover eight previously unknown entry points of interest for the spike protein. Four of them, researchers found, are functionally important for viral entry. The research was published earlier this month in the Journal of the American Chemical Society (JACS). It could expand the suite of tools used to fight the virus, particularly as it mutates and evolves ways to evade vaccines. To read the full story.
