The low number of mpeg:mCherry/arg2:GFP double-positive macrophages observed at 4 dpi, alongside arg2:GFP-positive neutrophils, did not appear to account for the many granuloma-associated arg2:GFP-positive cells that were observed, with many appearing to be mpeg:mCherry negative (Fig. 6B). Here, ARG2 is linked to Granuloma.
