TLR3 mRNA mean expression in polymorphonuclear and mononuclear cells in the COVID-19 SEVERE group was 1.82 and 1.77 respectively (p 0.931; Supplementary Table 3).TLR3 mRNA mean expression in polymorphonuclear was 2.06 in the MILD group and 1.82 in the SEVERE group however not statistically significant (p 0.821; Supplementary Table 3). The gene discussed is TLR3; the disease is COVID-19.
