Role and regulation of the melanization reaction in Drosophila immune response

In arthropods, the melanization reaction consists in the rapid synthesis of melanin at the site of infection and injury. A key enzyme in the melanization process is phenoloxidase (PO), which catalyzes the oxidation of phenols to quinones that subsequently ...

Cues and regulatory pathways involved in natural competence and transformation in pathogenic and environmental Gram-negative bacteria

Melanie Blokesch, Patrick Martin Seitz

Bacterial genomics is flourishing, as whole-genome sequencing has become affordable, readily available, and rapid. As a result, it has become clear how frequently horizontal gene transfer (HGT) occurs in bacteria. The potential implications are highly sign ...

Ergodic behaviour of "signed voter models"

Thomas Mountford, Grégory Maillard

We answer some questions raised by Gantert, Lowe and Steif (Ann. Inst. Henri Poincare Probab. Stat. 41 (2005) 767 780) concerning "signed" voter models on locally finite graphs. These are voter model like processes with the difference that the edges are co ...

Tissue- and ligand-specific sensing of gram-negative infection in drosophila by PGRP-LC isoforms and PGRP-LE

Bruno Lemaitre

The Drosophila antimicrobial response is one of the best characterized systems of pattern recognition receptor-mediated defense in metazoans. Drosophila senses Gram-negative bacteria via two peptidoglycan recognition proteins (PGRPs), membrane-bound PGRP-L ...

TransFLP - A Method to Genetically Modify Vibrio cholerae Based on Natural Transformation and FLP-recombination

Melanie Blokesch

Several methods are available to manipulate bacterial chromosomes(1-3). Most of these protocols rely on the insertion of conditionally replicative plasmids (e.g. harboring pir-dependent or temperature-sensitive replicons(1,2)). These plasmids are integrate ...

Synthesis, characterization and anticancer studies of mixed ligand dithiocarbamate palladium(II) complexes

Christine Neuhausen, Zia Ur Rehman

Six mixed ligand dithiocarbamate Pd(II) complexes (1-6) of general formula [(DT)Pd(PR3)Cl], where DT = dimethyldithiocarbamate (1, 5), diethyldithiocarbamate (2, 3), dicyclohexyldithiocarbamate (4), bis(2-methoxyethyl)dithiocarbamate (6); PR3 = benzyldiphe ...

Drosophila immunity: analysis of PGRP-SB1 expression, enzymatic activity and function

Bruno Lemaitre, Juan Camilo Paredes Escobar, David Welchman

Peptidoglycan is an essential and specific component of the bacterial cell wall and therefore is an ideal recognition signature for the immune system. Peptidoglycan recognition proteins (PGRPs) are conserved from insects to mammals and able to bind PGN (no ...

Spiroplasma and host immunity: activation of humoral immune responses increases endosymbiont load and susceptibility to certain Gram-negative bacterial pathogens in Drosophila melanogaster

Bruno Lemaitre, Jeremy Keith Herren

Spiroplasma poulsonii and its relatives are facultative, vertically transmitted endosymbionts harboured by several Drosophila species. Their long-term survival requires not only evasion of host immunity, but also that Spiroplasma does not have a net detrim ...

Quorum Sensing Contributes to Natural Transformation of Vibrio cholerae in a Species-Specific Manner

Melanie Blokesch, Patrick Martin Seitz, Gaia Francesca Marianne Suckow

Although it is a human pathogen, Vibrio cholerae is a regular member of aquatic habitats, such as coastal regions and estuaries. Within these environments, V. cholerae often takes advantage of the abundance of zooplankton and their chitinous molts as a nut ...

Non-uraninite products of microbial U(VI) reduction

Rizlan Bernier-Latmani, Elena Suvorova Buffat, Harish Veeramani, Jonathan Sharp, Elena Cristina Dalla Vecchia, Nicholas Wigginton

A promising remediation approach to mitigate subsurface uranium contamination is the stimulation of indigenous bacteria to reduce mobile U(VI) to sparingly soluble U(IV). The product of microbial uranium reduction is often reported as the mineral uraninite ...
