Drosomycin is an antimicrobial peptide gene that is a direct transcriptional target of Toll/NFκB signalling [24], so we used a Drosomycin-GFP reporter to detect its expression in the primary immune secretory tissue (fat body) of CIN larvae (Figure 2g, 2h). This evidence concerns the gene NFKB1 and cervical squamous intraepithelial neoplasia.
