3.4.21.78 up after spring viraemia of carp virus infection, transcripts accumulate in most immune-related tissues in a time-dependent manner. GzmA/K transcript is up-regulated in thymus tissue of GH transgenic carp 717616 3.4.21.78 up the expression of gzma gene in head-kidney leukocytes is significantly up-regulated against E-11 target cells compared to naive head-kidney leukocytes. mRNA levels of gzma is further increased during cell-mediated cytotoxicity assays against nodavirus-target cells 771416 3.4.21.78 up transcription of gzma is significantly up-regulated in seabream head-kidney leukocytes against mock-infected target cells compared to naive head-kidney leukocytes alone, and this up-regulation is even higher when the targets are infected with nodavirus 771416
