TLR4 and COVID-19: Since TLR7/TLR8 recognize single-stranded RNA from viruses such as SARS-CoV-2 and TLR4, a receptor that recognizes various endogenous and exogenous proteins which was predicted to strongly interact with the SARS-CoV-2 spike glycoprotein (Choudhury and Mukherjee, 2020), activation of these TLR signaling pathways can partially mimic the inflammatory response in COVID-19.
