How are forces transduced in a cellular environment?

How are forces transduced in a cellular environment?The application of the tensegrity, semiflexible chain and dipole polarization models to biological scenarios has proven most successful in the case of the tensegrity hypothesis (as reviewed in [...]

How is Energy Transferred Across the Cellular System?

How is Energy Transferred Across the Cellular System?Cellular systems function at a nanometer level and use a highly dynamic set of components. Both of these factors act as primary constraints that prevent the generation of [...]

Is Mechanosensing an Active Process?

Is Mechanosensing an Active Process?Types of MechanosensingWhen a cell periodically tests its external environment, a mechanical signal is converted to a chemical signal across the cell membrane. Adhesion receptors located on the external cell membrane [...]

How does the cytoskeleton transmit mechanical forces?

How does the cytoskeleton transmit mechanical forces?It is clear that mechanical forces and structural cues influence cell behavior by regulating signal processes. These signals go on to alter gene expression and reorganize the cytoskeleton and [...]

How do Focal Adhesions Facilitate Mechanosensing?

How do Focal Adhesions Facilitate Mechanosensing?Focal adhesions are known to sense both chemical and physical properties of their matrix environment. Chemical sensing is mediated by the different types of receptors that may function additively, synergistically [...]

What types of forces do cells encounter?

What types of forces do cells encounter?Cells and subcellular structures experience forces from a variety of sources. In general, forces are developed from within the cell via the cytoskeleton (endogenous forces) or come from outside [...]
