Scientists have uncovered new details about cellular filaments that play a critical role in wound healing, according to a ...

When stimulated by the autonomic nervous system to contract from the release of hormones or other chemical signals, smooth muscle cells shorten via the movement of actin and myosin myofilaments.

For example, endothelial cells could sense vasoactive factors and provide signals to the vascular smooth muscle cells ... top of the cell surface. This actin-myosin mesh features linker proteins ...

Their work, published in Nature Communications, reveals a mechanism of interdependence of different forms of the cytoskeletal proteins actin and myosin, and their functions. The team also ...

whereas the muscle tissue in the real human iris is made up of smooth muscle cells, which are a type of involuntary muscle tissue. They chose to pattern skeletal muscle cells in an iris-like pattern ...

The molecular motor myosin V transports cargo by stepping on actin filaments, executing a random diffusive search for actin binding sites at each step. A recent experiment suggests that the joint ...

Actin filaments assemble inside the nucleus in response to multiple cellular perturbations, including heat shock, protein misfolding, integrin engagement, and serum stimulation. We find that DNA ...
