In addition, we can manipulate the genome of zebrafish, and observe the effects on inflammation in vivo as they are transparent in their larval stages. This has exciting implications for the study of inflammatory diseases. We have established a model of inflammation in the zebrafish tail, in which caspase dependent cell death is required for resolution. For example, addition of the pan-caspase inhibitor zVD added at 4 hours after tailfin injury increases the number of neutrophils present from 6.0+/−1.0 to 28.9+/− 3.3 (mean +/− s.e.m. p<0.001 n = 3). The transparency of the larvae makes these an ideal model for the study of in vivo inflammation, and we have generated fluorescent systems for the easy visualisation of neutrophilic inflammation and resolution in vivo. We are also performing an unbiased forward genetic screen for mutants with defective resolution of inflammation, and to date have identified 38 putative mutants. These techniques allow new approaches to understanding the molecular controls of inflammation resolution. ER -
