A humoral stress response protects Drosophila tissues from antimicrobial peptides

Bruno Lemaitre, Matteo Dal Peraro, Jean Philippe Boquete, Chan Cao, Samuel Rommelaere, Fernando Augusto Teixeira Pinto Meireles, Alexia Laurie Carboni

An efficient immune system must provide protection against a broad range of pathogens without causing excessive collateral tissue damage. While immune effectors have been well characterized, we know less about the resilience mechanisms protecting the host ...
