To confirm the differential expression pattern of the itln family members in the zebrafish mycobacterial infection and to study the kinetics of the host response more carefully, we analyzed itln1 (ENSDARG00000007534), itln2, itln2-like and itln3 gene expression from the abdominal cavity organ blocks of M. marinum infected (6 CFU; SD 3 CFU) WT e46 background adult zebrafish with qPCR at 1 and 6 dpi, as well as at 4 and 9 weeks post infection (wpi) (Fig. 1B–E). Here, ITLN2 is linked to infection.
