A High-Throughput Microfluidic Platform for Mammalian Cell Transfection and Culturing

Mammalian synthetic biology could be augmented through the development of high-throughput microfluidic systems that integrate cellular transfection, culturing, and imaging. We created a microfluidic chip that cultures cells and implements 280 independent t ...

Identification and functional characterization of protein kinases that modulate Notch signaling under physiological conditions and in cancer

Chhavi Jain

The Notch signaling pathway is a key regulator of cell fate decisions in embryonic development and in adult tissue homeostasis. Mounting evidence suggests that Notch signaling is frequently deregulated in human neoplasms, where depending upon the cellular ...

A coiled coil switch mediates cold sensing by the thermosensory protein DesK

Matteo Dal Peraro, Luciano Andres Abriata, Thomas Lemmin

The thermosensor histidine kinase DesK from Bacillus subtilis senses changes in membrane fluidity initiating an adaptive response. Structural changes in DesK have been implicated in transmembrane signaling, but direct evidence is still lacking. On the basi ...

Fundamental Constraints on the Abundances of Chemotaxis Proteins

Anne-Florence Raphaëlle Bitbol

Flagellated bacteria, such as Escherichia coli, perform directed motion in gradients of concentration of attractants and repellents in a process called chemotaxis. The E. coli chemotaxis signaling pathway is a model for signal transduction, but it has uniq ...

Molecular Modeling of Membrane Embedded Proteins

Thomas Lemmin

Over the past years, molecular modeling and simulation techniques have had a major impact on experimental life sciences. They are capable of providing accurate insight into microscopic mechanisms, which are usually difficult to investigate experimentally. ...

Mycobacterium tuberculosis Requires Phosphate-Responsive Gene Regulation To Resist Host Immunity

John McKinney, Anna De Graff Tischler

Mycobacterium tuberculosis persists in the tissues of mammalian hosts despite inducing a robust immune response dominated by the macrophage-activating cytokine gamma interferon (IFN-gamma). We identified the M. tuberculosis phosphate-specific transport (Ps ...

Mitochondrial Dysfunction in Genetic Animal Models of Parkinson's Disease

Elpida Tsika, Darren Moore, Alzbeta Trancikova

Mitochondria are highly dynamic, multifunctional organelles. Aside from their major role in energy metabolism, they are also crucial for many cellular processes including neurotransmission, synaptic maintenance, calcium homeostasis, cell death, and neurona ...

Histone monoubiquitylation position determines specificity and direction of enzymatic cross-talk with histone methyltransferases Dot1L and PRC2

Beat Fierz

It is well established that chromatin is a destination for signal transduction, affecting many DNA-templated processes. Histone proteins in particular are extensively post-translationally modified. We are interested in how the complex repertoire of histone ...

Bioanalytical reagent, method for production thereof, sensor platforms and detection methods based on use of said bioanalytical reagent

Horst Vogel, Horst Pick

The invention relates to various embodiments of a bioanalytical reagent with at least one vesicle, generated from a living cell, comprising at least one receptor, characterized in that a mechanism of signal transduction triggered by said receptor in the ce ...

Membrane nanotubes drawn by optical tweezers transmit electrical signals between mammalian cells over long distances

Horst Vogel, Marinela Gjoni Boillat, Pedro Pascoal, Davor Kosanic

Biological cells continuously change shape allowing essential functions such as cell motility, vesicle-mediated release/uptake of soluble and membrane components or nanotube-mediated cell–cell communications. Here we use single cell micromanipulation to in ...
