objectives: acinetobacter baumannii is a gram-negative, non-motile aerobic bacterium known as a nosocomial pathogen resisting often to broad range of antibiotics. the pathogen is a serious agent of mortality and morbidity in hospital particularly among immunocompromise patients. treatment and control of its infections is complicated owing to its high antibiotic resistance, survival in various e...

Herpesviruses use a vesicle-mediated transfer of intranuclearly assembled nucleocapsids through the nuclear envelope (NE) for final maturation in the cytoplasm. The molecular basis for this novel vesicular nucleo-cytoplasmic transport is beginning to be elucidated in detail. The heterodimeric viral nuclear egress complex (NEC), conserved within the classical herpesviruses, mediates vesicle form...

The ability to recognize related cells in a population can confer evolutionary benefits. For example, some bacteria use contact-dependent inhibition proteins to distinguish kin from nonkin. Kinship recognition is taken to a new level in Myxococcus, which uses the dual-purpose TraA protein for kin recognition and outer membrane and lipoprotein exchange. In this issue of the Journal of Bacteriolo...

Both outer hair cell electromotility and neurotransmission at the inner hair cell synapse are rapid mechanical events that are synchronized to the hair-cell receptor potential. We analyze whether the forces and potentials resulting from membrane flexoelectricity could affect synaptic vesicle fusion. The results suggest that the coupling of membrane curvature with membrane potential is of suffic...
