SLC6 neurotransmitter transporters: structure, function, and regulation

Area of Science:

• Neuroscience
• Molecular Biology
• Pharmacology

Background:

• Neurotransmitter transporters (NTTs) of the solute carrier 6 (SLC6) gene family are crucial for neurotransmitter signaling and homeostasis in the mammalian brain.
• These transporters regulate extracellular neurotransmitter levels by mediating uptake into neurons and glial cells.
• SLC6 NTTs are key targets for therapeutic drugs used in treating psychiatric disorders and for psychostimulants like cocaine and amphetamines.

Purpose of the Study:

• To provide an updated review of recent advances in the understanding of SLC6 NTTs.
• To highlight the implications of new structural, functional, and pharmacological insights.
• To discuss the molecular and cellular mechanisms regulating NTT activity.

Main Methods:

• Review of high-resolution structural data, including prokaryotic homologs.
• Analysis of research on molecular and cellular mechanisms of transporter regulation.
• Synthesis of findings related to NTT pharmacology and therapeutic implications.

Main Results:

• Rapid advancements in understanding SLC6 NTT molecular structure, function, and pharmacology since 2005.
• Significant progress in elucidating the regulation of NTT activity at molecular and cellular levels.
• New insights into the role of SLC6 NTTs in neurotransmission and disease.

Conclusions:

• The study of SLC6 NTTs has seen substantial progress, enhancing our comprehension of their structure, function, and regulation.
• These transporters remain critical targets for developing treatments for various neurological and psychiatric conditions.
• Continued research promises further breakthroughs in understanding and manipulating NTTs for therapeutic benefit.
