Compartmentalized PGRP expression along the dipteran Bactrocera dorsalis gut forms a zone of protection for symbiotic bacteria

Bruno Lemaitre, Yichen Wang, Ping Zhang

All metazoan guts are subject to opposing pressures wherein the immune system must eliminate pathogens while tolerating the presence of symbiotic microbiota. The Imd pathway is an essential defense against invading pathogens in insect guts, but tolerance m ...

The Drosophila Baramicin polypeptide gene protects against fungal infection

Bruno Lemaitre, Mark Austin Hanson, Igor Iatsenko, Alice Marra

The fruit fly Drosophila melanogaster combats microbial infection by producing a battery of effector peptides that are secreted into the haemolymph. Technical difficulties prevented the investigation of these short effector genes until the recent advent of ...

Susceptibility to infection in early life: a growing role for human genetics

Jacques Fellay, Alessandro Borghesi

The unique vulnerability to infection of newborns and young infants is generally explained by a constellation of differences between early-life immune responses and immune responses at later ages, often referred to as neonatal immune immaturity. This devel ...

Unpaired extracellular cysteine mutations of CSF3R mediate gain or loss of function

Oliver Hantschel, Tim Kükenshöner

Exclusive of membrane-proximal mutations seen commonly in chronic neutrophilic leukemia (e.g. T618I), functionally defective mutations in the extracellular domain of the granulocyte colony-stimulating factor receptor (CSF3R) have been reported only in seve ...

Sirtuin 2 Deficiency Increases Bacterial Phagocytosis by Macrophages and Protects from Chronic Staphylococcal Infection

Johan Auwerx, Tytti Heinonen, Marc Pfefferlé

Sirtuin 2 (SIRT2) is one of the seven members of the family of NAD(+)-dependent histone deacetylases. Sirtuins target histones and non-histone proteins according to their subcellular localization, influencing various biological processes. SIRT2 resides mai ...

Thioester-containing proteins regulate the Toll pathway and play a role in Drosophila defence against microbial pathogens and parasitoid wasps

Bruno Lemaitre, Samuel Rommelaere, Anna Dostalova

Background: Members of the thioester-containing protein (TEP) family contribute to host defence in both insects and mammals. However, their role in the immune response of Drosophila is elusive. In this study, we address the role of TEPs in Drosophila immun ...

Toll-like receptor 8 agonist nanoparticles mimic immunomodulating effects of the live BCG vaccine and enhance neonatal innate and adaptive immune responses

Jeffrey Alan Hubbell, Melody Swartz, Sachiko Hirosue, Alexandre de Titta, Daniel Kenneth Bonner

Background: Newborns display distinct immune responses, leaving them vulnerable to infections and impairing immunization. Targeting newborn dendritic cells (DCs), which integrate vaccine signals into adaptive immune responses, might enable development of a ...

De novo identification of lipid II binding lipopeptides with antibacterial activity against vancomycin-resistant bacteria

Inmaculada Rentero Rebollo

Creative strategies for identifying new antibiotics are essential to addressing the looming threat of a post-antibiotic era. We here report the use of a targeted peptide phage display screen as a means of generating novel antimicrobial lipopeptides. Specif ...
