Melanoma Differentiation-Associated protein 5 (MDA5) is a member of the retinoic acid-inducible gene I (RIG-I)-like receptor (RLR) family, which are cytosolic pattern recognition receptors that detect viral nucleic acids. Here we show an Mda5-dependent response to rhabdovirus infection in vivo using a dominant-negative mda5 transgenic zebrafish. Dominant-negative mda5 zebrafish embryos displayed an impaired antiviral immune response compared to wild-type counterparts that can be rescued by recombinant full-length Mda5. To our knowledge, we have generated the first dominant-negative mda5 transgenic zebrafish and demonstrated a critical role for Mda5 in the antiviral response to rhabdovirus.
