Researchers have captured the assembly of the NLRP3 inflammasome inside intact human cells for the first time. These ...

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 ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on filopodia—sensitive, finger-like protrusions that reach out from the cell membrane ...

The colorful dots at the center are cytotoxic granules used to destroy infected or cancerous cells. Credit: F. Lemaitre @ ...

One of the most fundamental processes in all of biology is the spontaneous organization of cells into clusters that divide and eventually turn into shapes – be they organs, wings, or limbs. Scientists ...

A microscopic image shows small red centers connected by networks of branched and straight filaments. The team mixed purified actin monomers with precise concentrations of two nucleation-promoting ...
