H2BC21 and infection: Zebrafish larvae expressing GFP in macrophages (Tg(mpeg1:H2B-GFP)) or BFP in neutrophils (Tg(lyz:BFP)) were infected with A. fumigatus spores expressing mCherry, and treated with indomethacin or DMSO vehicle control and we enumerated the number of macrophages and neutrophils at the infection site through daily confocal imaging (Fig 3A).
