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 ...

SiliFish: A desktop application to model swimming behavior in developing zebrafish (Danio rerio)

Yann Roussel

SiliFish is an open-source desktop application tomodel and study zebrafish swimming. Here, we explain how to define the general parameters of the model, define cell populations, place them within the spinal cord, and define their projections. We explain ho ...

Towards understanding centriole elimination

Pierre Gönczy, Nils Kalbfuss

Centrioles are microtubule-based structures crucial for forming flagella, cilia and centrosomes. Through these roles, centrioles are critical notably for proper cell motility, signalling and division. Recent years have advanced significantly our understand ...

Comprehensive proteomic analysis of JC polyomavirus-infected human astrocytes and their extracellular vesicles

Samuel Jones, Alexey Sapozhnik

JC polyomavirus (JCPyV) is an opportunistic virus that remains in a latent state in the kidneys and lymphoid organs of more than half of the human adult population. In rare cases of severe immune suppression, the virus is able to establish a lytic infectio ...

CENP-A and CENP-B collaborate to create an open centromeric chromatin state

Beat Fierz, Harsh Nagpal, Wei Cai

Centromeres are epigenetically defined via the presence of the histone H3 variant CENP-A. Contacting CENP-A nucleosomes, the constitutive centromere associated network (CCAN) and the kinetochore assemble, connecting the centromere to spindle microtubules d ...

Automated Dual-Mode Cell Monitoring To Simultaneously Explore Calcium Dynamics and Contraction-Relaxation Kinetics within Drug-Treated Stem Cell-Derived Cardiomyocytes

Gerardo Turcatti, Pierre Marquet, Benjamin Rappaz, Bokyoung Kim

This manuscript proposes a new dual-mode cell imaging system for studying the relationships between calcium dynamics and the contractility process of cardiomyocytes derived from human-induced pluripotent stem cells. Practically, this dual-mode cell imaging ...

Neurogenesis redirects β-catenin from adherens junctions to the nucleus to promote axonal growth

Antonio Herrera Camacho

Here, we show that, in the developing spinal cord, after the early Wnt-mediated Tcf transcription activation that confers dorsal identity to neural stem cells, neurogenesis redirects beta-catenin from the adherens junctions to the nucleus to stimulate Tcfo ...

Countering T cell exhaustion and senescence for enhanced adoptive T cell therapies against solid tumors

Yang Zhao

CAR-T cell therapy has shown remarkable success in treating hematopoietic malignancies, but its efficacy in solid tumors is limited by T cell dysfunction, including exhaustion and senescence. In this study, we designed metabolically armored CAR-T cells to ...

The Antioxidant and Proapoptotic Effects of Sternbergia clusiana Bulb Ethanolic Extract on Triple-Negative and Estrogen-Dependent Breast Cancer Cells In Vitro

Laure Menin, Natalia Gasilova, Maria Younes

Background: Sternbergia clusiana belongs to the Amaryllidaceae family and is recognized for the valuable biological activity of its major bioactive compounds. The aim of the current is to evaluate the anticancer effects of the ethanolic bulb extract of Ste ...

Cortical cell assemblies and their underlying connectivity: an in silico study

Michael Reimann, András Ecker, Daniela Egas Santander, Sirio Bolaños Puchet, James Bryden Isbister

Recent developments in experimental techniques have enabled simultaneous recordings from thousands of neurons, enabling the study of functional cell assemblies. However, determining the patterns of synaptic connectivity giving rise to these assemblies rema ...

Microfluidic device combining hydrodynamic and dielectrophoretic trapping for the controlled contact between single micro-sized objects and application to adhesion assays

Philippe Renaud, Arnaud Bertsch, Clémentine Sophie Sarah Lipp

The understanding of cell-cell and cell-matrix interactions via receptor and ligand binding relies on our ability to study the very first events of their contact. Of particular interest is the interaction between a T cell receptor and its cognate peptide-m ...
