In this study, the subcellular localization, tissue distribution and response to grass carp reovirus ( GCRV ) infection and lipopolysaccharide ( LPS ) stimulation of four grass carp Ctenopharyngodon idellus toll‐like receptor 4 ( tlr4 ) genes were investigated. All four genes were constitutively expressed in all tissues studied, but the subcellular localization and tissue exhibiting the highest expression differed for each protein. Following GCRV infection, all the four tlr4s were upregulated in all tissues examined, and stimulation of C. idellus kidney ( CIK ) cells with LPS resulted in downregulation of all four tlr4s . These results provide a foundation for further investigation of tlr4 genes in bony fishes.
