Journal ArticleDOI
Inactivation of the dlt operon in Staphylococcus aureus confers sensitivity to defensins, protegrins, and other antimicrobial peptides.
TL;DR: A role of thed-alanine-esterified teichoic acids which occur in many pathogenic bacteria in the protection against human and animal defense systems is proposed.
Journal ArticleDOI
Staphylococcus aureus resistance to human defensins and evasion of neutrophil killing via the novel virulence factor MprF is based on modification of membrane lipids with L-lysine

TL;DR: A novel staphylococcal gene, mprF, which determines resistance to several host defense peptides such as defensins and protegrins constitutes a novel virulence factor, which may be of general relevance for bacterial pathogens and represents a new target for attacking multidrug resistant bacteria.
Journal ArticleDOI
H-2 class I knockout, HLA-A2.1-transgenic mice: a versatile animal model for preclinical evaluation of antitumor immunotherapeutic strategies
Hüseyin Firat,Francisco Garcia-Pons,Sophie Tourdot,Steve Pascolo,Antonio Scardino,Zacarias Garcia,Marie-Louise Michel,Ralph W. Jack,Günther Jung,Konstadinos Kosmatopoulos,Luis Mateo,Andreas Suhrbier,François A. Lemonnier,Pierre Langlade-Demoyen +13 more
TL;DR: HHD mice provide a versatile animal model for preclinical evaluation of peptide‐based cancer immunotherapy and CTL responses against five distinct epitopes could be elicited simultaneously in a single animal.
Journal ArticleDOI
Induction of exosome release in primary B cells stimulated via CD40 and the IL-4 receptor.
Sarah C. Saunderson,Petra C. Schuberth,Amy C. Dunn,Lilija Miller,Barry D. Hock,Philippa A. MacKay,Norbert Koch,Ralph W. Jack,Alexander D. McLellan +8 more
TL;DR: The results suggest that exosome release is not R constitutive activity of B cells, but may be induced following cell: cell signaling, and a link between the BCR and this exocytic pathway is demonstrated.
Journal ArticleDOI
Lantibiotics and microcins: polypeptides with unusual chemical diversity.
Ralph W. Jack,Günther Jung +1 more
TL;DR: In vitro studies with microcin B17 have helped to uncover the molecular mechanisms by which post-translational modification results in the formation of heterocyclic oxazole and thiazole rings, and the identification of the 'docking molecules' represents a step forward in the search for novel targets for future antibiosis.
