In vivo and in vitro approaches uncover a new function for the β-barrel OmpA and reveal how it interacts with the stress sensor lipoprotein RcsF.

Bacterial viruses are an unexpected ‘third party’ that imposes a strong predatory pressure on a bacterial pathogen during the natural course of infection in humans.

Molecular genetic analyses define the first homeostatic control pathway that maintains cell wall remodeling activity during bacterial growth.

Selective activation of FZD7 signaling with an engineered WNT mimetic promotes early developmental programs, including endodermal lineage specification, in human pluripotent stem cells.

Phosphatidylglycerol binding at multiple sites stabilizes the open state relative to the desensitized state of a pentameric ligand-gated ion channel.

Inside the acidic vacuole, expression, DNA binding and DNA binding affinity of the Salmonella regulator SsrB is stimulated by acid pH.

Several neuronal subtypes found in the early zebrafish olfactory placode are not derived from the neural crest, as previously thought, but from the preplacodal ectoderm.

Chemical ablation of olfactory sensory neurons blocks cerebrospinal fluid outflow into the nasal epithelium, leading to alterations of cerebrospinal fluid dynamics.

Dispensable loops shield the functionally-important extracellular loops of the essential Gram-negative bacterial outer membrane protein LptD from antibody interference.
