SARS-CoV-2 T-cell infection and HIV similarity - COVID-19 vaccines update 46

1 year ago

A new discovery that the SARS-CoV-2 virus can infect T-cells via LFA-1 protein which is also how HIV can infect T-cells. We also discuss the fact that the spike protein has been known to contain fragments also found in HIV proteins. However, it is not the spike protein that interacts with LFA-1 on the T-cells to allow infection and we discuss the alternative mechanisms of how SARS-CoV-2 infects T-cells, appearing to mimic what HIV viruses do.
