Magnetized stars with differential rotation and a differential toroidal field
, 2015 We have succeeded in obtaining magnetized equilibrium states with differential rotation and differential toroidal magnetic fields. If an internal toroidal field of a proto-neutron star is wound up from the initial poloidal magnetic field by differential ...

Pseudomonas aeruginosa gene products PilT and PilU are required for cytotoxicity in vitro and virulence in a mouse model of acute pneumonia [PDF]
, 1999 Type IV pili of the opportunistic pathogen Pseudomonas aeruginosa mediate twitching motility and act as receptors for bacteriophage infection. They are also important bacterial adhesins, and nonpiliated mutants of P.

Seminal Plasma Initiates a
mBio, 2014 Niche-restricted pathogens are evolutionarily linked with the specific biological fluids that are encountered during infection. Neisseria gonorrhoeae causes the genital infection gonorrhea and is exposed to seminal fluid during sexual transmission ...

Screening of a Haloferax volcanii Transposon Library Reveals Novel Motility and Adhesion Mutants
Life, 2016 Archaea, like bacteria, use type IV pili to facilitate surface adhesion. Moreover, archaeal flagella—structures required for motility—share a common ancestry with type IV pili.

Possible role of Geobacter sulfurreducens in anaerobic corrosion of steels [PDF]
, 2007 Geobacteraceae are the most widespread microorganisms in soils and sediments in which microbial reduction of Fe(III) is an important process, either in the natural degradation of organic compounds or in their bioremediation.

Meningococci drive host membrane tubulation to recruit their signaling receptors
Nature CommunicationsOnce passed into the bloodstream, bacterial pathogens have a limited time to interact with permissive receptors at the surface of host cells. Neisseria meningitidis has developed an extremely effective strategy allowing it to find its receptors in a few ...

Cooperative retraction of bundled type IV pili enables nanonewton force generation.
PLoS Biology, 2008 The causative agent of gonorrhea, Neisseria gonorrhoeae, bears retractable filamentous appendages called type IV pili (Tfp). Tfp are used by many pathogenic and nonpathogenic bacteria to carry out a number of vital functions, including DNA uptake ...

Rapid cytoskeletal response of epithelial cells to force generation by type IV pili.
PLoS ONE, 2011 Many bacterial pathogens interfere with cellular functions including phagocytosis and barrier integrity. The human pathogen Neissieria gonorrhoeae generates grappling hooks for adhesion, spreading, and induction of signal cascades that lead to formation ...

Novel applications of shotgun phage display [PDF]
, 2004 In a shotgun phage display library, theoretically, the entire proteome of a bacterium is represented. Phages displaying specific polypeptides can be isolated by affinity selection, while the corresponding gene remains physically linked to the gene ...
