Figure 7 (A) The percentage of larvae with neutrophil swarms at 3 hr post injury after gasdermin inhibitor, LDC7559, or DMSO treatment. Data shown are mean with a minimum of 120 larvae analysed in each group, accumulated from three biological replicates. Joined data represent each individual experiment using larvae from the same zebrafish lay over the two treatment groups (Figure 7—source data 1). (B) The percentage of larvae with neutrophil swarms at 4 hr post injury after neutrophil elastase inhibitor, MeOSu-AAPV-CMK, treatment, or DMSO control. Data shown are mean, with greater than 73 larvae per group over three biological replicates. Joined data represent each individual experiment using larvae from the same zebrafish lay over the two treatment groups (Figure 7—source data 2). (C) Representative fluorescence micrographs of the double transgenic Tg(mpx:GFP);Tg(lyz:nfsβ-mCherry) after myeloperoxidase knockdown using CRISPR-Cas9 with tyrosinase knockdown as a negative control. The myeloperoxidase guide RNA targeted the promoter of mpx, therefore knocking down expression of green mpx:GFP while leaving lyz:mCherry intact. White arrowhead indicates the presence of a swarm at the wound (white dashed line). (D) The percentage of larvae with neutrophil swarms at 4 hr post-injury after mpx knockdown by CRISPR-Cas9 or tyr control. Data shown are mean, with a minimum of 115 larvae analysed in each group, accumulated from three biological replicates (Figure 7—source data 3). Joined data represent each individual experiment using larvae from the same zebrafish lay over the two treatment groups. p-values in (A), (C), and (D) are generated from unpaired t-tests.
