TLR3 and COVID-19: It was observed that mRNA expression of TLR3 (fold change = 2.3, P = 0.016), TLR7 (fold change = 2.1, P = 0.033), TLR8 (fold change = 2.3, P = 0.022), and TLR9 (fold change = 2.4, P = 0.019) was significantly upregulated in the COVID-19- Group B versus Control-Group II (Table 3).
