Type IV pili mechanochemically regulate virulence factors in Pseudomonas aeruginosa

Alexandre Louis André Persat, Joanne Netter Engel

Bacteria have evolved a wide range of sensing systems to appropriately respond to environmental signals. Here we demonstrate that the opportunistic pathogen Pseudomonas aeruginosa detects contact with surfaces on short timescales using the mechanical activ ...

Mechanistic aspects of DNA uptake in naturally competent Vibrio cholerae

Patrick Martin Seitz

The physiological state of competence for natural transformation allows bacteria to take up free DNA from the environment and recombine it into their genome. As one of three modes of horizontal gene transfer, natural transformation has hence contributed su ...

Interplay between cytoskeletal forces, membrane tension and shape in rapidly migrating cells

Chiara Gabella

Cell migration is a fundamental process in all animal cells. The ability of cell to migrate is crucial for many pathological and physiological conditions such as morphogenesis, the immune response to inflammatory or vascular diseases and cancer metastasis. ...

Bioinspired, releasable quorum sensing modulators

Adrien Keith Lawrence, Karl Gademann

We demonstrate the synthesis and immobilization of natural product hybrids featuring an acyl-homoserine lactone and a nitrodopamine onto biocompatible TiO2 surfaces through an operationally simple dip-and-rinse procedure. The resulting immobilized hybrids ...

Single-Cell Analysis of Mycobacterial Persistence Using Microfabricated Tools

Meltem Elitas

Bacterial cells behave as individuals despite being genetically identical and subject to the same environment. Although the underlying mechanisms of cellular individuality are not well understood, temporal variation of gene expression and protein levels in ...

Microtechnologies to Map the Fate of Single Stem Cells and their Progeny

Stefan Kobel

Since stem cells have the unique ability to produce more of themselves (i.e. to "self-renew") and to generate specialized tissue cells, they are an ideal source of cells for regenerative medicine and in vitro tissue models. In order to fully exploit this p ...

Tissue engineering of the bladder

Catharina Adelöw

Stem cell use in bladder tissue engineering is a recently addressed area of investigation that has generated excitement as a novel way to restore and regenerate lost or damaged urinary bladder tissue. The remodelling of smooth muscle plays a significant ro ...

Miniaturized bioanalytics to probe the function of membrane proteins

Pedro Pascoal

G-protein coupled receptors (GPCRs) are the most abundant class of proteins in the cell body. Such receptors are of major interest as potential therapeutic targets. Downscaling and parallelization of bioanalytics opens novel routes to rapidly screen and id ...

A novel cell culture approach for tissue engineering based on surface expansion

Hicham Majd

Most tissue engineering approaches include the delivery of reparative cells to a damaged host tissue. Generally these cells are sought to be of a stem cell character since they retain a high potential for proliferation and differentiation into diverse phen ...

Dynamics of actin and myosin II during cell polarization and directional locomotion

Sophie Bohnet

Crawling cell motility is characteristic of most animal cells and is involved in many important biological processes such as embryogenesis, immune response, and wound healing. It involves several steps: protrusion (dynamic surface extension) at the front o ...
