This page provides comprehensive information about the cell type. See the content below for detailed information. [@brady1997]
GABAergic neurons are inhibitory neurons that exhibit selective vulnerability in various neurodegenerative diseases. Their dysfunction contributes to network hyperexcitability, seizures, and cognitive impairment. [@heckers1991]
Calcium dysregulation: PV neurons have high calcium
Oxidative stress: Susceptible to ROS
Protein aggregation: Selective inclusion formation
Consequences
Network hyperexcitability: Disinhibition
Seizure predisposition: Especially in AD
Oscillation disruption: Gamma rhythms impaired
Cognitive dysfunction: Memory/attention deficits
Circuit-Level Effects
Feedforward inhibition: Disrupted
Feedback inhibition: Impaired
Gain control: Altered
Therapeutic Implications
Enhancement Strategies
GABA-A modulators: Benzodiazepines (caution)
GABA-B agonists: Baclofen
GAD enhancement: Gene therapy approaches
Circuit Restoration
Optogenetic stimulation: PV neuron activation
Chemogenetic approaches: Designer receptors
Transplantation: GABAergic neuron grafts
Biomarkers
GABA levels in CSF
PET of GABA receptors
Electrophysiological markers
