A serpin mutant links Toll activation to melanization in the host defence of Drosophila

Ligoxygakis, Petros, Pelte, Nadège, Ji, Chuanyi, Leclerc, Vincent, Duvic, Bernard, Belvin, Marcia, ...

A prominent response during the Drosophila host defence is the induction of proteolytic cascades, some of which lead to localized melanization of pathogen surfaces, while others activate one of the...

Critical evaluation of the role of the Toll-like receptor 18-Wheeler in the host defense of Drosophila

Ligoxygakis, Petros, Bulet, Philippe, Reichhart, Jean-Marc

Essential aspects of innate immune responses to microbial infections appear to be conserved between insects and mammals. In particular, in both groups, transmembrane receptors of the Toll superfamily...

Requirements of peptidoglycan structure that allow detection by the Drosophila Toll pathway

Filipe, Sergio R, Tomasz, Alexander, Ligoxygakis, Petros

The Drosophila immune system is able to discriminate between classes of bacteria. Detection of Gram-positive bacteria involves a complex of two pattern recognition receptors: peptidoglycan...

Prophenoloxidase activation is not required for survival to microbial infections in Drosophila

Leclerc, Vincent, Pelte, Nadège, Chamy, Laure El, Martinelli, Cosimo, Ligoxygakis, Petros, Hoffmann, Jules A, ...

The antimicrobial defence of Drosophila relies on cellular and humoral processes, of which the inducible synthesis of antimicrobial peptides has attracted interest in recent years. Another potential...

Sensing of Gram-positive bacteria in Drosophila: GNBP1 is needed to process and present peptidoglycan to PGRP-SA

Wang, Lihui, Weber, Alexander N R, Atilano, Magda L, Filipe, Sergio R, Gay, Nicholas J, Ligoxygakis, Petros

Genetic evidence indicates that Drosophila defense against Gram-positive bacteria is mediated by two putative pattern recognition receptors acting upstream of Toll, namely Gram-negative binding...
