PGLYRP1 and bacterial infectious disease: To further confirm the hypothesis that a single PGRP-LB isoform, PGRP-LBPD, was implicated in the control of egg-laying behavior during bacterial infection, we generated via the CRISPR-Cas9 technology, two PGRP-LBRDspecific alleles which delete part of the PGRP-LBRD specific exon (Figure 2—figure supplement 1B).
