a RLRs are activated by RNA derived from a virus or bacteria and mediate the production of type I and III IFNs and inflammatory cytokines via the MAVS adaptor protein. Interferons released into the extracellular compartment activate interferon-stimulated genes and induce direct antiviral responses. b Positive regulation of RLRs by posttranslational modifications and interacting proteins. c Negative regulation of RLRs by posttranslational modifications and interacting proteins.
