Our paper on SARS-CoV-2 evasion of NK cell killing is officially out in @CellReports! tldr; SARS-CoV-2 suppresses danger signals that are supposed to help NK cells recognize and kill infected cells so the virus can spread instead of being stopped by the immune system. A 🧵(1/10) NK cells are supposed to kill virally-infected cells to stop the virus from spreading. Unfortunately, they’re terrible at killing SARS-CoV-2-infected targets compared to uninfected “bystander” cells! 2/10

We have a new preprint out today on biorxiv examining the ability of NK cells to kill SARS-CoV-2-infected cells! tldr; they’re pretty terrible at it.
biorxiv.org/content/10.110…

A tweetorial: (1/11) To gauge how well healthy NK could specifically kill SARS-CoV-2-infected cells, we infected A549-ACE2s with enough virus to get 50% of cells infected after 48 hours. Then, we performed flow-based killing assays using purified, healthy NK cells. (2/11)
