E-I balance and human diseases - from molecules to networking

Area of Science:

• Neuroscience
• Molecular Biology
• Systems Biology

Background:

• Neuronal excitability is crucial for brain information transfer.
• A homeostatic balance between excitatory and inhibitory systems is established during development.
• This excitation-inhibition (E-I) balance is fundamental for proper brain function.

Purpose of the Study:

• To review recent molecular mechanisms involved in establishing and maintaining the E-I balance.
• To examine the deregulation of E-I systems at molecular, network, and disease levels.
• To provide insights into the neurobiological basis of E-I balance disorders.

Main Methods:

• Literature review of recent research on E-I balance.
• Analysis of molecular mechanisms governing neuronal excitability.
• Examination of network and disease-level implications of E-I imbalance.

Main Results:

• Detailed overview of molecular players in E-I balance.
• Examples of E-I system deregulation across different investigation levels.
• Identification of key molecular pathways critical for E-I homeostasis.

Conclusions:

• The E-I balance is a complex process orchestrated by specific molecular mechanisms.
• Deregulation of E-I balance is implicated in various neurological and psychiatric disorders.
• Understanding these mechanisms is vital for developing therapeutic strategies for brain diseases.
