The immune system is tightly regulated by the activity of stimulatory and inhibitory immune receptors. Using gene expression datasets, Halwani and coworkers showed a pattern of overall upregulation of immune inhibitor receptors on different myeloid and lymphoid cells during SARS-CoV-2 infection. This dysregulation may contribute to the immunopathology and severity of COVID-19.
