acmsd-/- zebrafish retain normal numbers and activation of microglia. Representative images from wholemount immunohistochemistry against 4c4 in acmsd+/+ (A) and acmsd-/- (B) siblings at 5dpf (scale bar = 100 µm). C No difference was found in the number of 4c4+ cells between acmsd+/+ and acmsd-/- larvae in the forebrain, midbrain, or these combined (whole brain) (p = 0.9827 for forebrain, p = 0.9925 for midbrain, p = 0.9836 for whole brain). D No difference in microglial activation, represented as the percentage of amoeboid cells out of the total 4c4+ cell count, was identified between genotypes (p = 0.6983 for forebrain, p = 0.8307 for midbrain, p = 0.8441 for whole brain). n = 31 acmsd-/-, 27 acmsd+/+, from three biological replicates. Statistics analysed by two-way ANOVA with post hoc Sidak’s multiple comparisons test.
