Different roles of membrane potentials in electrotaxis and chemotaxis of dictyostelium cells.
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 Dictyostelium cells to tolerate drastic V(m) changes, we i...
متن کاملGenetic analysis of the role of G protein–coupled receptor signaling in electrotaxis
Cells display chemotaxis and electrotaxis by migrating directionally in gradients of specific chemicals or electrical potential. Chemotaxis in Dictyostelium discoideum is mediated by G protein-coupled receptors. The unique Gbeta is essential for all chemotactic responses, although different chemoattractants use different receptors and Galpha subunits. Dictyostelium amoebae show striking electro...
متن کاملA large-scale screen reveals genes that mediate electrotaxis in Dictyostelium discoideum.
Directional cell migration in an electric field, a phenomenon called galvanotaxis or electrotaxis, occurs in many types of cells, and may play an important role in wound healing and development. Small extracellular electric fields can guide the migration of amoeboid cells, and we established a large-scale screening approach to search for mutants with electrotaxis phenotypes from a collection of...
متن کاملNormal chemotaxis in Dictyostelium discoideum cells with a depolarized plasma membrane potential.
We examined a possible role for the plasma membrane potential in signal transduction during cyclic AMP-induced chemotaxis in the cellular slime mold Dictyostelium discoideum. Chemotaxis, cyclic GMP and cyclic AMP responses in cells with a depolarized membrane potential were measured. Cells can be completely depolarized by two different methods: (1) by treatment with azide; this probably causes ...
متن کاملLocal modulation of chemoattractant concentrations by single cells: dissection using a bulk-surface computational model
Chemoattractant gradients are usually considered in terms of sources and sinks that are independent of the chemotactic cell. However, recent interest has focused on 'self-generated' gradients, in which cell populations create their own local gradients as they move. Here, we consider the interplay between chemoattractants and single cells. To achieve this, we extend a recently developed computat...
