During growth in biofilms and host infection, the opportunistic pathogen Pseudomonas aeruginosa employs respiratory heterocomplexes that support extracellular electron shuttling and pathogenicity.

Genetic and molecular analyses reveal the decisive role of fatty acid oxidation (FAO) acting downstream to the ROS-JNK circuit essential for hemocyte progenitor differentiation in Drosophila..

C. elegans utilizes bacterially produced nitric oxide as a sensory cue to elicit avoidance of pathogenic bacteria.

Plasmodium parasites secrete RhopH2 from the rhoptry organelle into their host red blood cell to facilitate the uptake of essential nutrients required for parasite replication and survival.

A structural and functional analysis of the electron transfer complex between a sulfite oxidase and its redox protein partner reveals an elegant compromise between the requirements for fast and efficient electron transfer and reaction specificity.

Discovery of the structural basis for recognition and uptake of a human precursor for body odour production reveals an important role for bacterial peptide transport and novel routes to prevent its production in humans.

The death of bacterial kin cells releases a danger signal that activates a posttranscriptional response in surviving cells, resulting in the rapid elaboration of interbacterial competition factors.

Cell replenishment within the airways is governed by the random division of a population of basal progenitor cells, in a process that is accelerated in smokers.

Feedback from the intestine during infection can modulate the behavior, learning, and microbial perception of the host.
