Title: | Calcium signalling in glial cells |
Creators Name: | Verkhratsky, A. and Kettenmann, H. |
Abstract: | Glial cells respond to a variety of external stimuli such as neurotransmitters, hormones or even mechanical stress by generating complex changes in the cytoplasmic Ca2+ concentration. This Ca2+ signal is controlled by an interplay of different mechanisms including plasmalemmal and intracellular Ca2+ channels, Ca2+ transporters and cytoplasmic Ca2+ buffers. In astrocytes, the Ca2+ signal can travel as waves within the syncytium spreading via gap junctions which might be regarded as a possible means for interglial communication. Ca2+ signalling is also an important medium for neurone-glia interaction: neuronal activity can trigger Ca2+ signals in glial cells and, in turn, there is evidence that glial Ca2+ signals can elicit responses in neurones. While glial cells are not equipped with the proper channels to generate action potentials, Ca2+ signalling could be the instrument by which these cells integrate and propagate signals in the CNS. |
