Résumé
TRIM proteins play a crucial antiviral effector role in the innate immune system of vertebrates. In this study, we found that TRIM proteins exhibited the highest expression levels in immune organs such as spleen and kidney during IHNV infection in rainbow trout, meanwhile, we successfully amplified TRIM23 and TRIM32 from diseased rainbow trout and analyzed their gene sequences, revealing that rainbow trout TRIM23 and TRIM32 proteins are closely related to Atlantic salmon and Chinook salmon; In this experiment, the TRIM23 and TRIM32 protein genes were resoundingly constructed as a recombinant plasmids and expressed in CHSE-214 cells. Upon transfected with the recombinant plasmid, followed by viral infection, significant decreasion in the copy numbers of the virus was observed, indicating that the TRIM23 and TRIM32 proteins of rainbow trout play an important role in inhibiting virus replication, with the TRIM32 role being the most pronounced. These results provide a basis for subsequent in-depth study of the antiviral effects of TRIM proteins, and provide new ideas for immune enhancers.
