Chemoattractant signaling in dictyostelium discoideum.
Dictyostelium is an accessible organism for studies of signaling via chemoattractant receptors. Chemoattractant-mediated signaling events and components are reviewed and presented as a series of connected modules, including excitation, inhibition, G protein-independent responses, early gene expression, inositol lipids, PH domain-containing proteins, cyclic AMP signaling, polarization acquisitio...
متن کاملNavigating signaling networks: chemotaxis in Dictyostelium discoideum.
Studies of chemotaxis in the social amoeba Dictyostelium discoideum have revealed numerous conserved signaling networks that are activated by chemoattractants. In the presence of a uniformly distributed stimulus, these pathways are transiently activated, but in a gradient they are activated persistently and can be localized to either the front or the back of the cell. Recent studies have begun ...
متن کاملTyrosine Phosphorylation-Mediated Signaling Pathways in Dictyostelium
While studies on metazoan cell proliferation, cell differentiation, and cytokine signaling laid the foundation of the current paradigms of tyrosine kinase signaling, similar studies using lower eukaryotes have provided invaluable insight for the understanding of mammalian pathways, such as Wnt and STAT pathways. Dictyostelium is one of the leading lower eukaryotic model systems where stress-ind...
متن کاملExtracellular purinergic signaling in pancreas.
recognized as important extracellular signaling molecules in many biological systems (1). In epithelia, ATP signaling is thought to regulate fluid transport, and exocrine glands are one of the first epithelia where the effect of ATP on ion channels and Ca signaling was observed (2, 3). Nevertheless, many steps in ATP signaling, also known as purinergic signaling, remain to be clarified. This in...
متن کاملExtracellular ATP signaling in plants.
Extracellular adenosine-5'-triphosphate (ATP) induces a number of cellular responses in plants and animals. Some of the molecular components for purinergic signaling in animal cells appear to be lacking in plant cells, although some cellular responses are similar in both systems [e.g. increased levels of cytosolic free calcium, nitric oxide (NO), and reactive oxygen species (ROS)]. The purpose ...
