Dorsal Raphe Nucleus Gabaergic Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Dorsal raphe nucleus (DRN) GABAergic neurons are local interneurons that produce gamma-aminobutyric acid (GABA) within the dorsal raphe nucleus. These neurons play crucial roles in modulating serotonergic output and are implicated in various neuropsychiatric and neurodegenerative conditions.
Location
Dorsal raphe nucleus GABAergic neurons are located within the:
Dorsal raphe nucleus (primarily in the lateral and ventral wings)
Median raphe nucleus (in some subsets)
Marker Genes
GAD1/GAD67: Glutamate decarboxylase
GAD2/GAD65: Glutamate decarboxylase
VGAT: Vesicular GABA transporter
PV: Parvalbumin (in some subsets)
Neurotransmitter
Primary: GABA
May co-release: Some subsets also release serotonin
