Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment ...

How and when did cells gain the ability to crawl? Live imaging of cells from close relatives of early eukaryotes fills in a ...

A CRISPR-based experimental and modeling study identifies profilin as a regulator that coordinates branched actin-network ...

Every time a white blood cell engulfs a bacterium, a neuron extends a projection to connect with a neighboring cell, or when a cancer cell forcefully squeezes through tissue to spread, the cell must ...

Scientists at Université de Montréal's Institute for Research in Immunology and Cancer (IRIC) have identified a dynamic structure that forms a network on the surface of epithelial cells. Led by ...

Chara corallina myosin XI (CcXI) drives the movement of actin filaments, which spontaneously form ring-like structures due to a slight curvature that leads to polar alignment. Living cells are highly ...

A Northwestern Medicine study has shed light on one of the most intricate construction projects in biology: how cells build and coordinate the internal scaffolding needed to create a healthy egg. The ...

Cells can spontaneously change shape even without external signals, but the underlying mechanisms behind this form of self-organization have remained unclear. Now, researchers from Japan have ...
