AI Article Synopsis
- - Voltage-gated ion channels are crucial for maintaining membrane potential and regulating electrical signals in neurons, with voltage-gated potassium channels (K) being particularly important for neuronal excitability.
- - High levels of reactive oxygen species (ROS) in the aging brain can impact K channels, contributing to aging and neurodegeneration, especially in conditions like Alzheimer's, Parkinson's, and Huntington's diseases.
- - The review highlights specific K channels affected in these disorders (K1, K2.1, K3, K4, K7) and suggests that modulators of these channels may serve as potential therapeutic targets to prevent or treat neurodegenerative diseases.
Article Abstract
Voltage-gated ion channels are essential for membrane potential maintenance, homeostasis, electrical signal production and controlling the Ca flow through the membrane. Among all ion channels, the key regulators of neuronal excitability are the voltage-gated potassium channels (K), the largest family of K channels. Due to the ROS high levels in the aging brain, K channels might be affected by oxidative agents and be key in aging and neurodegeneration processes. This review provides new insight about channelopathies in the most studied neurodegenerative disorders, such as Alzheimer Disease, Parkinson's Disease, Huntington Disease or Spinocerebellar Ataxia. The main affected K channels in these neurodegenerative diseases are the K1, K2.1, K3, K4 and K7. Moreover, in order to prevent or repair the development of these neurodegenerative diseases, previous K channel modulators have been proposed as therapeutic targets.
