Only IL-6 and IL-1RA were significantly higher in Omicron BA.2 virus-infected HNECs compared to D614G, Gamma, and Delta infections (IL-6 D614G vs BA.2 p = 0.0377, p = 0.0093; IL-1RA Delta vs BA.2 p = 0.0174, Gamma vs BA2 p = 0.0063, Delta vs BA.2 p = 0.0065) D614G (Fig. 2A). This evidence concerns the gene IL6 and infection.
