www.uni-bayreuth.deCell Movement Without MotorsPhysicists from the Universities of Bayreuth and Grenoble have discovered a new mechanism of cell mobility. Their findings challenge the classical dogma that the molecular motor myosin is essential for the movement of mammalian cells. This insight paves the way for new strategies to control cell movement, with potential implications for the treatment of diseases. The team reports their findings in the leading physics journal Physical Review Letters.

About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also overexpressed in many types of cancer. This makes it a promising target for cancer therapies. However, drugs that inhibit Plk1 have often proven ineffective.

Bytes Europe · Scientists Recreate the Conditions That Sparked Complex LifeThe original version of this story appeared in Quanta Magazine.Far from being solo operators, most single-celled microbes are in complex relationships. In the ocean, the soil, and your gut, they might battle and eat each other, exchange DNA, compete for nutrients, or feed on one another’s by-products. Sometimes they get even more intimate: One cell might slip inside another and make itself comfortable. If the conditions are just right, it might stay and be welcomed, sparking a relationship that could last for generations—or billions of years. This phenomenon of one cell living inside another, called endosymbiosis, has fueled the evolution

#Cells seem to like to keep their proportions. All thru the process of spreading on a substrate, we find conserved ratios in size of #lamella (under which cell #FocalAdhesion patches grow) and cell body. We show that this requires the interplay of some global regulation (based on #mechanical interactions?) with local processes.

The team of Prof. Benoît Ladoux, principal investigator of “Tissue Mechanobiology” at the Max-Planck-Institut für Physik und Medizin (MPZPM) have demonstrated how physical signals can have an impact on the fate of extruding cells governing their death or survival. The results may establish novel paths for understanding tissue properties in both normal and pathological conditions.

#Soft #Cells are a class of shapes with curved edges that can tile 2D planes or 3D spaces. They were discovered in 2024 by Gabor Domokos, Alain Goriely, Akos G. Horvath, and Krisztina Regos.
