Area of Science:

Neuroscience
Molecular Biology
Cell Biology

Context:

Glutamate transporters are crucial plasma membrane proteins in neurons and glial cells.
They regulate glutamatergic neurotransmission and protect against glutamate toxicity.
Recent cloning of these transporters has accelerated research.

Purpose:

To review recent advancements in the study of high-affinity glutamate transporters.
To focus on molecular structure, expression patterns, physiological roles, and structure-function relationships.

Summary:

High-affinity glutamate transporters actively uptake glutamate from the extracellular space.
This process terminates excitatory neurotransmission and maintains low extracellular glutamate levels.
The article highlights progress in understanding transporter molecular architecture, localization, functional significance, and structure-activity correlations.

Impact:

Provides a comprehensive overview of current research on glutamate transporters.
Facilitates understanding of neuronal communication and neuroprotection mechanisms.
Informs future research directions in neuropharmacology and neurological disease.
