Scientific summary

Gliotransmission defines the modulation of neuronal activity by the active release of transmitters such as ATP, glutamate, D-serine and GABA by glial cells (Ben Achour and Pascual, 2010). A significant amount of evidences indicate that modulations of astrocytic gliotransmission impact various vegetative and cognitive functions such as sleep homeostatsis, memory and ventilation (Ben Achour and Pascual, 2012). Astrocytes a sub type of glial cells, have been particularly studied but the gliotransmitter release mechanisms are still controversial.

We have recently described a modulation of astrocytic gliotransmission by microglia another type of glial cells during inflammation (Pascual et al., 2012). Our goal is to better understand the communication between microglia, astrocytes and neuron and to determine how the phenotypic changes of glial cells associated to most brain diseases affects gliotransmission.

To do so we rely on live transgenic animals models, imaging and electrophysiological approaches.
