SARS-CoV-2 and interferon blockade

Mol Med. 2020 Nov 9;26(1):103. doi: 10.1186/s10020-020-00231-w.

Abstract

The response to viral infection generally includes an activation of the adaptive immune response to produce cytotoxic T cells and neutralizing antibodies. We propose that SARS-CoV-2 activates the innate immune system through the renin-angiotensin and kallikrein-bradykinin pathways, blocks interferon production and reduces an effective adaptive immune response. This model has therapeutic implications.
