Dexamethasone mediated immunosuppression does not alter the survival of itln3 deficient zebrafish in a mycobacterial infection. (A) A schematic representation of the performed experiment. M. marinum inoculate used in the infections were 47 CFU (SD 4 CFU). (B) Representative flow cytometry plots in WT (itln3uta148) zebrafish at -1 wpi and 2 wpi used for quantifying lymphocyte, myeloid cell and precursor cell populations. FSC = forward scatter, SSC = side scatter. (C,D) Lymphocyte fractions of the total cell populations for both WT and itln3 knockout zebrafish at -1 wpi and 2 wpi. Both the itln3uta145 (n = 12 in all groups) and itln3uta148 background fish (n = 8 in all groups) are shown. Blood cell samples were run as technical duplicates. (E,FM. marinum burden (log10) in 100 ng of zebrafish DNA were measured at 2 wpi and 4 wpi by qPCR in the infected dexamethasone treated zebrafish organ blocks (without the kidney). All bacterial quantification samples were run once. Group sizes at 2 and 4 wpi, respectively, were as follows: WT (itln3uta145) n = 9, n = 8; iltn3uta145/uta145n = 9, n = 10; WT (itln3uta148) n = 6, n = 9 and iltn3uta148/uta148 n = 7, n = 8. A two-tailed Mann-Whitney test was used in the statistical comparison of differences.

Homozygous itln3uta145/uta145 and itln3uta148/uta148 mutants develop normally. A) F3-progeny of itln3uta145/+ and itln3uta148/+ zebrafish were imaged at 1, 4 and 7 dpf. The larvae were anesthetized for imaging with 0.02% 3-amino benzoic acid ethyl ester (Sigma-Aldrich) at 4 and 7 dpf, and the embryos collected for genotyping at 7 dpf. Representative images of itln3uta145/145 and itln3uta148/148 mutants as well as the corresponding WT embryos are shown. Micrographs were taken with Zeiss Lumar V12 fluorescence microscope and Axiocam MRm digital camera using a bright field exposure of 2 ms. A 23.5x-magnification was used at 1 dpf and a 15.0x-magnification at 4 and 7 dpf. B) 12-month-old WT (itln3uta145), itln3uta145/145 , WT (itln3uta148) and itln3uta148/148 female and male zebrafish were anesthetized with 0.02% 3-amino benzoic acid ethyl ester (Sigma-Aldrich) and imaged submerged in water using Canon EOS 7D Mark II camera with an exposure time of 8 ms. Brightness was increased by 20% for all of the images in panel B using Windows Photo Viewer. All images in panels A-B were cropped to exclude unnecessary empty background from the figure.
