Objective
In addition to the classical, polarised release of neurotransmitter that takes place at synapses, neurones communicate with each other through another, and less well understood mechanism called retrograde inhibition. Here neurones emit a messenger molecule from their somatodendritic membrane when they fire action potentials, and this molecule induces an inhibitory signal in the axon and synaptic terminals ofpresynaptic neurones. The aim of this proposal is to test whether retrograde inhibition results from the exocytotic release of classical neurotransmitters from the somatodendritic domain of the releasing neuron, and to compare this type ofexocytosis with that taking place at axon terminals. The participation of novelexocytotic proteins, which are insensitive to clostridia neurotoxins, will be investigated. Methods will include molecular biology, immunohistochemistry, electron microscopy, patch-clamp recording and amperommetry.
