Integrins as mechanochemical transducers.
A recent resurgence of interest in mechanical forces and cell shape as biological regulators has revealed extracellular matrix as the site at which forces are transmitted both to and from cells. at the same time, great advances have been made in terms of defining cell-surface integrin receptors as transmembrane molecules that mediate cell attachment and physically interlink extracellular matrix with the intracellular cytoskeleton. Convergence of these two lines of research has begun to elucidate the molecular mechanism by which cells sense physical forces and transduce mechanical signals into a biochemical response.
