[Neuropsychiatric disorders and GABA].

Area of Science:

• Neuroscience
• Neurobiology
• Molecular Neuroscience

Context:

• The mammalian central nervous system (CNS) relies on the balance between excitatory (glutamate) and inhibitory (GABA) signaling for proper neural function.
• The inhibitory GABAergic system involves multiple key molecules, including glutamate decarboxylase, GABA transporters, GABA receptors, and GABA transaminase.

Purpose:

• To review recent research connecting the malfunction of GABAergic signaling molecules to the etiology of neuropsychiatric disorders.
• To explore novel therapeutic strategies targeting GABAergic signaling components, excluding GABA receptors.

Summary:

• Abnormalities in GABAergic signaling molecules are implicated in severe neuropsychiatric conditions such as epilepsy, depression, schizophrenia, stiff-person syndrome, and drug addiction.
• This review synthesizes current understanding of how GABAergic system disruptions contribute to these disorders.
• Emerging therapeutic avenues focus on targeting other GABAergic molecules for potential clinical applications.

Impact:

• Highlights the critical role of GABAergic signaling balance in CNS function and neuropsychiatric health.
• Provides insights into the molecular underpinnings of various neurological and psychiatric conditions.
• Suggests future directions for developing targeted therapies for neuropsychiatric disorders by focusing on a broader range of GABAergic molecules.
