Abstract:
The workshop "Actin & Cell Polarity" will be held on January 22nd, 2008 at Warwick Systems Biology Centre (University of Warwick, Coventry, UK).
Motion of animal cells in response to extracellular signals, e.g. a gradient of chemical attractant, requires cells to polarise and establish a leading front, which is functionally different from the cell rear. The front-rear axis determines the direction of motion. Protrusion of the front is based on polymerisation of actin, which pushes the cell membrane forward.
Directional plant cell growth also depends on cellular polarization and on the actin cytoskeleton. Sites of polar plant cell expansion are established in response to gradients of extracellular signals, which include plant hormones, and are maintained by a complex intracellular signal network controlled by Rho family small GTPases (Rac/Rop GTPases).
The main goal of the workshop is to excite discussions on generic mechanisms of regulatory control of cell polarity and possible perspectives for theoretical modelling. Contributions from experimental plant and animal cell biologists will be supplemented by a talk on theoretical modelling of cell polarity.
The workshop is jointly organized by Till Bretschneider (Warwick Systems Biology Centre) and Benedikt Kost (Warwick HRI).
