Cellular protrus ion and contraction\, crucial aspects of motility and migration\, are typi cally assumed to be driven by the RhoGTPases Rac and Rho\, respectively. N ear sites of protrusion\, integrin-based adhesions spontaneously assemble and serve as both biochemical signaling hubs that feedback onto the local balance of Rac and Rho activity levels (e.g.\, through phosphorylation of the adhesion-associated protein paxillin) as well as force transmission po ints that cells can use to displace their bulk. This bidirectional feedbac k between biochemical activities and cellular displacement/mechanics makes understanding how cellular processes interact collectively with external cues to produce motility a challenging task. To complement the existing ex perimental methods used to study this system\, we use computational modeli ng approaches to explore some facets of cellular motility. That includes ( 1) investigating how front-to-rear polarity\, as well as certain motility phenotypes\, are produced by the spatio-temporal dynamics of RhoGTPases ar ising from of a combination of their intrinsic molecular properties and bi ochemical signaling\; (2) developing a biophysical model that describes th e nanoscale formation of integrin-based adhesions capable of explaining ex perimental variations in integrin density and predicting the mechanical co nditions required for self-assembly of adhesions\; and (3) focusing on a c ellular-scale model of protrusion to show how local interactions between m aturing adhesions and VASP\, an anti-capping protein for actin filaments\, produce a variety of spatio-temporal patterns of protrusion\, and how mec hanical feedback through adhesions modifies these patterns. These results are compared to experimental findings to give more insight than would be f easible to achieve solely through experiments.\n\nThis seminar will be giv en online via Zoom.
