Abstract:
In a recent issue of Cell, Coureuil et al. (2010) show that type IV pili of Neisseria meningitidis-the causative bacterium of cerebrospinal meningitis-bind to the endothelial β2-adrenoceptor and elicit biased β-arrestin signaling resulting in microvilli formation and paracytotic bacterial migration.
Insights
Neisseria meningitidis uses type IV pili to bind to endothelial β2-adrenoceptors. This interaction triggers signaling that leads to bacterial migration and meningitis.
Area of Science:
- Microbiology
- Cell Biology
- Immunology
Background:
- Neisseria meningitidis is a bacterium that causes meningitis.
- Type IV pili are involved in bacterial adhesion and invasion.
- Endothelial receptors play a role in host-pathogen interactions.
