The co-stimulated salmon (i.e., ASAL/lice) showed higher transcript levels of the putatively immune-related GOIs toll-like receptor 13 (tlr13), C-type lectin domain family 1 member B (clec1b), hepcidin antimicrobial peptide A (hampa), cathelicidin antimicrobial peptide B (campb), saa5, tyrosine-protein kinase Lyn (lyn), B-cell lymphoma 6 protein (bcl6), interleukin 4 receptor (il4r), and chloride intracellular channel 2 (clic2) than the other injection/infection groups (EMM pairwise comparisons; Figures 7A, D, J, L, M, S, U, V, Y). This evidence concerns the gene IL4R and infection.
