TLR2 and COVID-19: In this work, we observed an overexpression of TLR2 and its coupled MyD88 adaptor in tracheal tissue from COVID-19/B.1.1.7 patients (Figure 1; p < 0.0001 vs. COVID-19/B.1 patients), while only MyD88 was overexpressed in COVID-19/B.1 variant (Figure 1; p = 0.0077 vs. control patients).
