A GABA reuptake inhibitor (GRI) is a type of drug which acts as a reuptake inhibitor for the neurotransmitter gamma-Aminobutyric acid (GABA) by blocking the action of the gamma-Aminobutyric acid transporters (GATs). This in turn leads to increased extracellular concentrations of GABA and therefore an increase in GABAergic neurotransmission. [1]
Like other GABA-T inhibitors, γ-acetylenic GABA causes GABA levels in the brain to be elevated. This is due to 4-aminobutyrate transaminase being the enzyme that converts γ-aminobutyric acid to L-glutamate. Inhibiting the enzyme stops this conversion from happening.
The Mayo Clinic Cancer Center is one of the oldest NCI-designated cancer centers in the United States, having first been designated in 1973. [3] The main location of the Mayo Clinic is in Rochester, MN. Campuses in Arizona and Florida opened later and became part of the Mayo Clinic Cancer Center in 2003. [4] [5]
In pharmacology, GABA A receptor positive allosteric modulators, also known as GABAkines or GABA A receptor potentiators, [1] are positive allosteric modulator (PAM) molecules that increase the activity of the GABA A receptor protein in the vertebrate central nervous system. GABA is a major inhibitory neurotransmitter in the central nervous system.

Inhibition of GABA transaminase enzymes reduces the degradation of GABA, leading to increased neuronal GABA concentrations. Examples include valproic acid , [ 2 ] vigabatrin , [ 3 ] [ 4 ] phenylethylidenehydrazine (and drugs that metabolize to it, such as phenelzine [ 5 ] ), ethanolamine- O -sulfate (EOS), and L- cycloserine .
The Hazelden Clinic in Minnesota is perhaps the most influential treatment center in the country, noted not just for its rehabilitation facilities but for its academic publishing arm. Founded in the late 1940s on a farm, the clinic brought order and professionalism to the 12-step method.
Typically, dementia is associated with classic symptoms like confusion and memory loss. But new research finds that there could be a less obvious risk factor out there: your cholesterol levels.
