Scientific Background
The transport of Glu into the cells by the EAAT transporters is coupled to the Na+ and K+ electrochemical gradient as a driving force. Hence, the uptake of Glu is dependent on the co-transport of three Na+ and one H+ ions, and the counter transport of one K+ ion.
In addition, to the well documented Glu uptake, the EAAT transporters show a Glu-independent Cl- conductance. The physiological significance of the Cl- current through the EAATs is currently unknown.1,2
EAAT1 as well as EAAT2, is expressed predominantly in glia cells (hence its original name: glial glutamate transporter or GLAST), while EAAT3, EAAT4 and EAAT5 are mostly expressed in neurons.
Three vesicular glutamate transporters (VGLUTs) have been cloned: BNPI/VGLUT1 (a brain-specific sodium dependent inorganic phosphate (Pi) transporter), and its homologs DNPI/VGLUT2 (differentiation-associated sodium-dependent Pi transporter) and VGLUT33. These transporters mediate glutamate uptake inside presynaptic vesicles and are anatomical and functional markers of glutamatergic excitatory transmission4.
