The Claim
Pharmacological blockade of the excitatory amino acid transporter (EAAT) with TBOA increases extracellular glutamate concentration without changing glutamine levels in human cortical slices.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Blocking a specific transporter that removes glutamate from brain tissue increases glutamate levels outside cells but does not change glutamine levels, showing that glutamine release does not require glutamate to be taken back up by this transporter.
See the scientific wording
Pharmacological blockade of the excitatory amino acid transporter (EAAT) with TBOA significantly increases extracellular glutamate without altering glutamine levels in human cortical slices, indicating that glutamine release is not directly dependent on glutamate reuptake via EAAT.
When the brain's glutamate cleanup system is blocked, glutamate builds up outside brain cells, but the amount of glutamine released does not change because glutamine release is controlled separately from glutamate uptake.
What the research says
1 studyStudy: Transmitter self-regulation by extracellular glutamate in fresh human cortical slices
When scientists blocked the brain’s glutamate cleanup system in human brain tissue, glutamate built up, but glutamine didn’t change — meaning glutamine isn’t made just because glutamate is being cleaned up.
