Vimentin intermediate !laments form part of the cytoskeleton
of mesenchymal cells, but under pathological conditions often
associatedwith in"ammation, vimentin !laments depolymerize as
the result of phosphorylation or citrullination, and vimentin
oligomers are secreted or released into the extracellular environment.
In the extracellular space, vimentin can bind surfaces of cells
and the extracellular matrix, and the interaction between extracellular
vimentin and cells can trigger changes in cellular functions,
such as activation of !broblasts to a !brotic phenotype. The
mechanism by which extracellular vimentin binds external cell
membranes and whether vimentin alone can act as an adhesive
anchor for cells is largely …

The ability of cells to take and change shape is a fundamental feature underlying development, wound repair, and tissue maintenance. Central to this process is physical and signaling interactions between the three cytoskeletal polymeric networks: F-actin, microtubules, and intermediate filaments (IFs). Vimentin is an IF protein that is essential to the mechanical resilience of cells and regulates cross-talk among the cytoskeleton, but its role in how cells sense and respond to the surrounding extracellular matrix is largely unclear. To investigate vimentin’s role in substrate sensing, we designed polyacrylamide hydrogels that mimic the elastic and viscoelastic nature of in vivo tissues. …
