Abstract
Our understanding of the physical principles organizing the genome in the nucleus is limited by the lack of tools to directly exert and measure forces on interphase chromosomes in vivo and probe their material nature. Here, we introduce an approach to actively manipulate a genomic locus using controlled magnetic forces inside the nucleus of a living human cell. We observed viscoelastic displacements over micrometers within minutes in response to near-piconewton forces, which are consistent with a Rouse polymer model. Our results highlight the fluidity of chromatin, with a moderate contribution of the surrounding material, revealing minor roles for cross-links and topological effects and challenging the view that interphase chromatin is a gel-like material. Our technology opens avenues for future research in areas from chromosome mechanics to genome functions.

Abstract
The remote actuation of cellular processes such as migration or neuronal outgrowth is a challenge for future therapeutic applications in regenerative medicine. Among the different methods that have been proposed, the use of magnetic nanoparticles appears to be promising, since magnetic fields can act at a distance without interactions with the surrounding biological system. To control biological processes at a subcellular spatial resolution, magnetic nanoparticles can be used either to induce biochemical reactions locally or to apply forces on different elements of the cell. Here, we show that cell migration and neurite outgrowth can be directed by the forces produced by a switchable parallelized array of micro-magnetic pillars, following the passive uptake of nanoparticles. Using live cell imaging, we first demonstrate that adherent cell migration can be biased toward magnetic pillars and that cells can be reversibly trapped onto these pillars. Second, using differentiated neuronal cells we were able to induce events of neurite outgrowth in the direction of the pillars without impending cell viability. Our results show that the range of forces applied needs to be adapted precisely to the cellular process under consideration. We propose that cellular actuation is the result of the force on the plasma membrane caused by magnetically filled endo-compartments, which exert a pulling force on the cell periphery.

Abstract
Bordetella pertussis fimbriae are composed of a major subunit, Fim2 or Fim3, and the minor subunit FimD. Using immunoelectron microscopy, we provide evidence that FimD is located at the fimbrial tip. The role of FimD in colonization of the mouse respiratory tract was studied by using two fimbrial mutants: a mutant completely devoid of fimbriae (designated FimD-) and a mutant devoid of the major fimbrial subunits but still producing the minor subunit (designated FimD+). The ability of the two fimbrial mutants to colonize the nasopharynx, trachea, and lungs was compared with those of the wild type parental strain and a filamentous hemagglutinin (FHA) mutant. Of the three mutants studied, the FimD- mutant showed the greatest defect, colonizing less well in the nasopharynx, trachea, and lungs. The most pronounced defect in colonizing ability of the three mutants was observed in the trachea. However, the colonizing defect of the FHA and FimD+ mutants in the trachea was observed only during the first 3 days of infection. After 10 days, the colonization level was nearly restored to wild-type levels. The FHA and FimD+ mutants showed a slight colonization defect in the nasopharynx but no defect in the lungs. A maltose binding protein-FimD fusion protein and a peptide derived from FimD were able to bind to heparin, a member of a class of sulfated sugars which are ubiquitous in the respiratory tract. Recently it was shown (W. L. W. Hazenbos, C. A. W. Geuijen, B. M. van den Berg, F. R. Mooi, and R. van Furth, J. Infect. Dis. 171:924-929, 1995) that FimD also binds to the integrin VLA-5, and our results suggest that the binding of B. pertussis to these two molecules plays an important role in colonization of the respiratory tract of the mouse.
