Abstract
Zebrafish lines expressing nitroreductase (NTR) in specific cell compartments, which sensitizes those cells to metronidazole (MTZ)-mediated ablation, have proven extremely useful for studying tissue regeneration and investigating cell function. In contrast to many cells, neutrophils are comparatively resistant to the NTR/MTZ targeted ablation strategy. Recently, a rationally engineered variant of NTR (NTR 2.0) has been described that exhibits greatly improved MTZ-mediated ablation efficacy in zebrafish. We show that a transgenic line with neutrophil-restricted expression of NTR 2.0 demonstrates complete neutrophil ablation, with an MTZ dose 100-fold less than current treatment regimens, and with treatment durations as short as 5 h.
