Universal Casimir attraction between filaments at the cell scale

The electromagnetic Casimir interaction between dielectric objects immersed in salted water includes a universal contribution that is not screened by the solvent and therefore long-ranged. Here, we study the geometry of two parallel dielectric cylinders. W ...

Investigating the bioaccumulation potential of anionic organic compounds using a permanent rainbow trout liver cell line

Kristin Schirmer, Juliane Hollender, Fabian Gerhard Peter Balk

Permanent rainbow trout (Oncorhynchus mykiss) cell lines represent potential in vitro alternatives to experiments with fish. We here developed a method to assess the bioaccumulation potential of anionic organic compounds in fish, using the rainbow trout li ...

Dissecting centriole fate in C. elegans development

Nils Kalbfuss

The presence of centrioles is critical for fundamental cell and developmental processes, including polarity, migration and division. Although centrioles are present in most proliferating cells, they are thought to vanish after cell cycle exit in some diffe ...

Characterization of Pseudomonas aeruginosa mechanosensing through label-free imaging of type IV pili

Lorenzo Anton-Louis Talà

Bacteria are ubiquitously found in all sorts of environment. They're found in the ocean, soil, or even in our guts or on our skin. Independently of their niche, they can transition from a planktonic state were they freely swim in an aqueous environment to ...

Analysis and Modeling of the Dynamics of Traction Forces during Cell Polarization and their Role in the Organization of Edge Activity

Zeno Messi

The capacity to break symmetry and organize activity to move directionally is a fundamental property of eukaryotic cells. To explain the organization of cell-edge activity, models commonly rely on front-to-back gradients of functional components or regulat ...

Self-organized patterning of cell morphology via mechanosensitive feedback

Marko Popovic

Tissue organization is often characterized by specific patterns of cell morphology. How such patterns emerge in developing tissues is a fundamental open question. Here, we investigate the emergence of tissue-scale patterns of cell shape and mechanical tiss ...

Expression of E-Cadherin in Epithelial Cancer Cells Increases Cell Motility and Directionality through the Localization of ZO-1 during Collective Cell Migration

Hwanseok Jang

Collective cell migration of epithelial tumor cells is one of the important factors for elucidating cancer metastasis and developing novel drugs for cancer treatment. Especially, new roles of E-cadherin in cancer migration and metastasis, beyond the epithe ...

The influence of the crowding assumptions in biofilm simulations

Vassily Hatzimanikatis, Liliana Angeles Martinez

Author summary In nature, many organisms grow in crowded biofilms that protect against stressful conditions, making their control/eradication a challenge. Modeling these microbial systems is a valuable tool for studying the interactions among cells and exp ...

Engineered Extracellular Matrices with Integrated Wireless Microactuators to Study Mechanobiology

Mahmut Selman Sakar, Erik Mailand, Nikolaos Bouklas, Fazil Emre Uslu

Mechanobiology explores how forces regulate cell behaviors and what molecular machinery are responsible for the sensing, transduction, and modulation of mechanical cues. To this end, probing of cells cultured on planar substrates has served as a primary ex ...

GRASP55 regulates intra-Golgi localization of glycosylation enzymes to control glycosphingolipid biosynthesis

Giovanni D'Angelo, Charlotte Julie Caroline Gehin, Laura Capolupo, Riccardo Rizzo

The Golgi apparatus, the main glycosylation station of the cell, consists of a stack of discontinuous cisternae. Glycosylation enzymes are usually concentrated in one or two specific cisternae along the cis-trans axis of the organelle. How such compartment ...
