Resource summary
Glial Cells
Have Glutamate transporters
Annotations:
bind glu and remove it from cleft - cessation of Excitatory transmission
Astrocytes -hindering diffusion of Glu and GABA in the EC space
thus regulate intersynaptic communication between neighbouring synapses and hence overall volume transmission in the brain
E.g. Glutamate spillover onto preS gp2/3 mGluRs on GABAergic synapses
this would decrease GABA release
Piet et al 2004
HFS - lots of GABA release
Activates Pre-S GABAb receptors of Glutamatergic synapses
Decreases Glu Release
