title: PGRP-LB minds the fort.
abstract: Peptidoglycan recognition proteins (PGRPs) are a class of molecules that play a critical role in Drosophila immunity. In this issue of Immunity, Zaidman-Rémy et al. (2006) show that PGRP-LB controls systemic immune responses as well as homeostasis at the barrier surfaces.
