Hookworms Evade Host Immunity by Secreting a Deoxyribonuclease to Degrade Neutrophil Extracellular Traps

Arne Seitz, Romain Guiet, Nicola Harris, Beatrice Volpe, Tiffany Babette Angélique Bouchery, Kathleen Shah, Mati André Marie Moyat, Manuel Kulagin

Hookworms cause a major neglected tropical disease, occurring after larvae penetrate the host skin. Neutrophils are phagocytes that kill large pathogens by releasing neutrophil extracellular traps (NETs), but whether they target hookworms during skin infec ...

Development of Sample-Adaptable Holders for Lightsheet Microscopy

Thierry Laroche, Olivier Burri, Arne Seitz, Lalit Kumar Dubey

Multi-user core microscopy facilities are often faced with the challenge to adapt or modify existing instruments. This is essential in order to fulfill the requirements of the user community, who wants to image a wide range of model organisms with varying ...

Cellular Uptake and Intracellular Trafficking of Poly(N-(2-Hydroxypropyl) Methacrylamide)

Anders Meibom, Harm-Anton Klok, Graham Knott, Stéphane Laurent Escrig, Olivier Burri, Arne Seitz, Claudia Battistella, Romain Guiet

Cellular uptake and intracellular trafficking of polymer conjugates or polymer nanoparticles is typically monitored using fluorescence-based techniques such as confocal microscopy. While these methods have provided a wealth of insight into the internalizat ...

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

Pierre Gönczy, Benita Wolf, Olivier Burri, Arne Seitz

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 ...

A formin-nucleated actin aster concentrates cell wall hydrolases for cell fusion in fission yeast

Thierry Laroche, Arne Seitz, Omaya Pierre Dudin, Raphaël Groux

Cell-cell fusion is essential for fertilization. For fusion of walled cells, the cell wall must be degraded at a precise location but maintained in surrounding regions to protect against lysis. In fission yeast cells, the formin Fus1, which nucleates linea ...

Antibody-Mediated Trapping of Helminth Larvae Requires CD11b and Fc gamma Receptor I

Arne Seitz, Romain Guiet, Duncan-Bruce Sutherland, Nicola Harris, Benjamin John Marsland, Beatrice Volpe, Julia Esser-von Bieren, Manuel Kulagin

Infections with intestinal helminths severely impact on human and veterinary health, particularly through the damage that these large parasites inflict when migrating through host tissues. Host immunity often targets the motility of tissue-migrating helmin ...

Correlative multicolor 3D SIM and STORM microscopy

Pierre Gönczy, Arne Seitz, Paul Guichard, Romain Guiet, Virginie Hamel, Isabelle Fluckiger, Mathias Fournier

Within the last decade, super-resolution methods that surpass the diffraction limit of light microscopy have provided invaluable insight into a variety of biological questions. Each of these approaches has inherent advantages and limitations, such that the ...

Antibodies Trap Tissue Migrating Helminth Larvae and Prevent Tissue Damage by Driving IL-4Rα-Independent Alternative Differentiation of Macrophages

Arne Seitz, Romain Guiet, Nicola Harris, Beatrice Volpe, Alessandra Piersigilli, Julia Esser-von Bieren, Ilaria Mosconi, Fei Chen

Approximately one-third of the world's population suffers from chronic helminth infections with no effective vaccines currently available. Antibodies and alternatively activated macrophages (AAM) form crucial components of protective immunity against chall ...

Automated analysis of single stem cells in microfluidic traps

Matthias Lütolf, Alessandra Griffa, Arne Seitz, Olivier Burri, Stefan Kobel, Mukul Girotra

We report a reliable strategy to perform automated image cytometry of single (non-adherent) stem cells captured in microfluidic traps. The method rapidly segments images of an entire microfluidic chip based on the detection of horizontal edges of microflui ...
