An ultra-fast mechanically active cell culture substrate

Herbert Shea, Cristina Martin Olmos, Matthias Imboden, Samuel Rosset, Alexandre Poulin, Francesca Sorba

We present a mechanically active cell culture substrate that produces complex strain patterns and generates extremely high strain rates. The transparent miniaturized cell stretcher is compatible with live cell microscopy and provides a very compact and por ...

Single live cell monitoring of protein turnover reveals intercellular variability and cell cycle dependence of degradation rates

Andrea Brigitta Alber

Cells need to be able to precisely control their proteome composition in order to maintain homeostasis. This is of particular relevance in fast dividing cells, such as embryonic stem cells, since their global protein levels need to be doubled at each divis ...

TRACMIT: An effective pipeline for tracking and analyzing cells on micropatterns through mitosis

Pierre Gönczy, Olivier Burri, Arne Seitz, Benita Wolf

The use of micropatterns has transformed investigations of dynamic biological processes by enabling the reproducible analysis of live cells using time-lapse fluorescence microscopy. With micropatterns, thousands of individual cells can be efficiently image ...

T-cell surface modification with synthetic nanomaterials for cell-mediated delivery to the central nervous system

Maxime Ayer

The future of medicine lies in therapeutic approaches that can specifically target sites of disease and induce a localized and effective therapeutic effect. Cell-mediated delivery, especially using cells of the circulatory repertoire such as T lymphocytes, ...

A Microfluidic Platform Enables Large-Scale Single-Cell Screening to Identify Genes Involved in Bacterial Persistence

Amanda Verpoorte

Persistent cells, representing a small fraction of a bacterial population, are refractory to antibiotic therapy. It is a phenotypic transient state. The underlying mechanisms of persistence remain largely unknown, but even divergent hypotheses agree on a f ...

Identification of aminopyrimidine-sulfonamides as potent modulators of Wag31-mediated cell elongation in mycobacteria

Stewart Cole, Kai Johnsson, John McKinney, Graham Knott, Neeraj Dhar, Ruben Hartkoorn, Anthony Vocat, Gaëlle Séraphine Kolly, Jan Lars Rybniker, Edina Rita Székely, François Signorino-Gelo, Isabella Santi, Monica Rengifo Gonzalez

There is an urgent need to discover new antitubercular agents with novel mechanisms of action in order to tackle the scourge of drug-resistant tuberculosis. Here, we report the identification of such a molecule - an AminoPYrimidine-Sulfonamide (APYS1) that ...

Phenotypic Heterogeneity in Mycobacterium tuberculosis

John McKinney, Neeraj Dhar, Giulia Manina

The interaction between the host and the pathogen is extremely complex and is affected by anatomical, physiological, and immunological diversity in the microenvironments, leading to phenotypic diversity of the pathogen. Phenotypic heterogeneity, defined as ...

Globally Optimal Cell Tracking using Integer Programming

Pascal Fua, Engin Türetken, Xinchao Wang, Carlos Joaquin Becker

We propose a novel approach to automatically track- ing cell populations in time-lapse images. To account for cell occlusions and overlaps, we introduce a robust method that generates an over-complete set of competing detection hypotheses. We then perform ...

CAST: An automated segmentation and tracking tool for the analysis of transcriptional kinetics from single-cell time-lapse recordings

Felix Naef, Benjamin Zoller, Damien Lionel Nicolas, Simon Blanchoud, Onur Tidin

Fluorescence and bioluminescence time-lapse imaging allows to investigate a vast range of cellular processes at single-cell or even subcellular resolution. In particular, time-lapse imaging can provide uniquely detailed information on the fine kinetics of ...

Stressed Mycobacteria Use the Chaperone ClpB to Sequester Irreversibly Oxidized Proteins Asymmetrically Within and Between Cells

Michaël Unser, John McKinney, Neeraj Dhar, Olivia Mariani

Mycobacterium tuberculosis (Mtb) defends itself against host immunity and chemotherapy at several levels, including the repair or degradation of irreversibly oxidized proteins (IOPs). To investigate how Mtb deals with IOPs that can neither be repaired nor ...
