IL6 and infection: We measured the levels of mRNA encoding for interleukins IL-6 and IL-1β and interferons IFN-α and IFN-β, which can inhibit viral replication by interaction with viral components and modulation of the host cell metabolism [43], and TLR-7, which is an endosomal pattern recognition receptors that can detect viral RNA at the site of infection to induce an inflammatory response [49].
