Homogenization theory captures macroscopic flow discontinuities across Janus membranes

François Gallaire, Pier Giuseppe Ledda, Giuseppe Antonio Zampogna, Kevin Wittkowski

Janus membranes, thin permeable structures with chemical and geometrical asymmetric properties, show great potential in industrial separation processes. Yet the link between the micro- and macro-scale behaviours of these membranes needs to be established r ...

Simultaneous Electrophysiology and Imaging Reveal Changes in Lipid Membrane Thickness and Tension upon Uptake of Amphiphilic Gold Nanoparticles

Francesco Stellacci, Paulo Henrique Jacob Silva, Camilla Servidio, Xufeng Xu

Amphiphilic gold core nanoparticles (AmNPs) striped with hydrophilic 11-mercapto-1-undecanesulfonate (MUS) and hydrophobic 1-octanethiol (OT) ligands are promising candidates for drug carriers that passively and nondisruptively enter cells. Yet, how they i ...

Engineered substrates incapable of induction of chondrogenic differentiation compared to the chondrocyte imprinted substrates

Philippe Renaud, Shahin Bonakdar, Leila Montazeri, Zahrasadat Ghazali

It is well established that surface topography can affect cell functions. However, finding a reproducible and reliable method for regulating stem cell behavior is still under investigation. It has been shown that cell imprinted substrates contain micro- an ...

Dynamics of CLIMP-63 S-acylation control ER morphology

Kathryn Hess Bellwald, Béatrice Kunz, Graham Knott, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Vassily Hatzimanikatis, Patrick Alain Sandoz, Robin Alexander Denhardt-Eriksson, Sylvia Ho, Luciano Andres Abriata, Catherine Maclachlan, Gard Spreemann

A key player in the formation of endoplasmic reticulum sheets is CLIMP-63, but mechanistic details remained elusive. Here authors combined cellular experiments and mathematical modelling to show that S-acylation of CLIMP-63 regulates its function by mediat ...

Bioengineering human mini-intestines with in vivo-like complexity and function

Olga Mitrofanova

Biological research heavily relies on the use of animal models, which has made it difficult to answer specific questions about human biology and disease. However, with the advent of human organoids - miniature versions of tissues generated in 3D human stem ...

Deciphering the molecular events leading to the global restoration of the chromatin landscape during mitotic exit

Silja Michelle Placzek

Two fundamental properties of embryonic stem cells (ESCs) are their ability to self-renew and differentiate into all somatic cell types. Maintenance of their identity faces major challenges when transitioning through mitosis, as most DNA-binding proteins a ...

Combination of dielectrophoretic and hydrodynamic traps for the controlled contact between cells or beads and application to adhesion assays

Clémentine Sophie Sarah Lipp

Multicellular organisms require very well organized and finely balanced cell-cell communication, adhesion and coordination to ensure the organisms homeostasis. These functions rely on specialized receptors placed at the cells membrane whose binding to thei ...

Identifying genetic and dietary modulators of metabolic disorders using systems genetics

Xiaoxu Li

Long-term consumption of lipid-rich foods can contribute to common metabolic diseases and systemic low-grade inflammation. However, dietary responses and the development of non-communicable diseases are shaped by genetic factors and gene-by-environment int ...

Charge-Selectively Permeable Self-Healing Microcapsules

Esther Amstad, Chuen-Ru Li

Microcapsules possessing a selective permeability are well-suited vessels for conducting cell studies or chemical reactions that require selective exchanges of reagents over a prolonged time. Most currently reported microcapsules are single-use delivery ca ...

Centriole elimination during Caenorhabditis elegans oogenesis initiates with loss of the central tube protein SAS-1

Pierre Gönczy, Mary-Claude Croisier-Coeytaux, Coralie Busso, Tamara Mikeladze-Dvali, Marie Juliette Ségolène Pierron, Keshav Jha, Alexander Woglar

In most metazoans, centrioles are lost during oogenesis, ensuring that the zygote is endowed with the correct number of two centrioles, which are paternally contributed. How centriole architecture is dismantled during oogenesis is not understood. Here, we ...

Multivalent Virucidal Antivirals: Synthesis, Mechanisms of Action, and Immune-stimulating Effects

Yong Zhu

Viruses initiate invasion by binding to cell surface glycoproteins. Materials mimicking the carbohydrate motifs of these glycoproteins, such as heparan sulfate (HS) and sialic acid (SA) can block viral attachment and inhibit the infection. Multivalent disp ...
