The first MDA5 was identified from sea perch.
5">LjMDA5 transcripts were constitutively expressed in all examined tissues.
LjMDA5 transcripts were induced greatly in immune and non-immune organs post NNV infection in vivo.
5">LjMDA5 involved in response to LPS and poly(I:C) stimulation and NNV infection in vitro.
Silencing of LjMDA5 by RNAi benefited the replication and virus production of RGNNV in vitro.
