New mechanism clarifies how cells migrate

Similarly to cars, cells need a steering mechanism that guides them towards a certain target or direction. Scientists at the Center for Cognition and Sociality (Institute for Basic Science, IBS), and KAIST, led by Prof. HEO ...

How cell nuclei squeeze into tight spaces

As cells move throughout our bodies, they often have to squeeze through tight nooks and crannies in their environment, reliably springing back to their original shape. The structures involved in this process are still a mystery, ...

The first stage of the cascade

G proteins are molecular switches on the insides of cell membranes. They convey important signals to the inner workings of the cells. The associated receptors are targeted by all kinds of medications. Scientists at the Technical ...

Neural stem cells control their own fate

To date, it has been assumed that the differentiation of stem cells depends on the environment they are embedded in. A research group at the University of Basel now describes for the first time a mechanism by which hippocampal ...

Random walk into captivity

The cell's internal skeleton undergoes constant restructuring. LMU physicists now show that its constituent proteins can be efficiently transported to their sites of action by diffusion – provided they can be arrested when ...

Global crosstalk limits gene regulation

Scientists at the interface of biophysics, evolutionary biology and systems biology develop new framework to analyze effects of global crosstalk on gene regulation | interdisciplinary collaboration between three IST Austria ...

Driving myelination by actin disassembly

(Phys.org)—If a metallurgist wanted to determine how a blade was made they might cut a small cross section, mount, polish, and etch it, and then look at it under a microscope. They could probably tell right away whether ...
