Abstract

Cyclic nucleotides control a number of neuronal properties including neuronal differentiation, pathfinding, regulation of excitability and synaptic transmission, and control of gene expression. Signaling events mediated by cAMP or cGMP are transient and take place within the complex 3-dimensional structure of the neuronal cell. Signaling events happen on the time scale of seconds to minutes and the biological significance of the temporal dimension remains poorly understood. Structural features of neurons (dendritic spines and branches, cell body, nucleus, axon…) as well as AKAPs and other scaffolding proteins that keep signaling enzymes together and form "signaling microdomains", are critical spatial determinants of signal integration. Finally, the types of enzymes involved in signal integration, which are expressed as a number of different types and splice variants, yield another dimension that determines signal integration properties. Biosensor imaging provides direct temporal and spatial measurement of intracellular signals. This novel approach, together with more conventional methods such as biochemistry, electrophysiology, and modeling, now provide a better understanding of the spatial and temporal features of cyclic nucleotide signal integration in living neurons. This topic aims at providing a better understanding of how neurons are "making sense" of cyclic nucleotide signaling in living neurons.

Abstract

The tale of cyclic GMP has been astonishing. Having overcome an initial disbelief, cyclic GMP has risen to its present eminence as a premium cellular signal transduction messenger of not only hormonal extracellular but also of the intracellular signals. This research topic focuses on the pathways and functions of membrane guanylate cyclases in different tissues of the body and their interplay with intracellular sensory signals where in many cases, cyclic GMP along with Ca2+ have taken on roles as synarchic co-messengers.
