Proteins barge in to turn off unneeded genes

(Phys.org)—The sorcerer's apprentice started a water-carrying system, but couldn't stop it, and soon he was up to his neck in water, and trouble. Living cells have a better design: When they activate a gene, they have a ...

Gauging the forces between cells

Cell-cell junctions are important for communication, transport, signalling, waste evacuation and water homeostasis. An European project has investigated how biophysical forces can influence the fulfilment of this vast range ...

The path from stem cell to maturity

Regulation of gene expression is essential to make sure cell maturation occurs as it should. European research is taking an integrated perspective on how selected steps in liver and blood cell differentiation can be modulated.

Human cells build protein cages to trap invading Shigella

In research on the never-ending war between pathogen and host, scientists at the Pasteur Institute in Paris have discovered a novel defensive weapon, a cytoskeletal protein called septin, that humans cells deploy to cage ...
