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.

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

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.

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

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

There is a strand-based evolutionary mechanism for the diversification of outer membrane proteins, which has implications for how repeat proteins are created and for how outer membrane proteins fold.

Biochemical and genetic experiments show that Ebf and Lhx2 cooperate to specify olfactory receptor enhancers, which cooperate to drive olfactory receptor expression.

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.
