Different roles of membrane potentials in electrotaxis and chemotaxis of dictyostelium cells.
Published in Eukaryotic Cell
Many types of cells migrate directionally in direct current (DC) electric fields (EFs), a phenomenon termed galvanotaxis or electrotaxis. The directional sensing mechanisms responsible for this response to EFs, however, remain unknown. Exposing cells to an EF causes changes in plasma membrane potentials (V(m)). Exploiting the ability of Dictyosteli...
