Mechanistic correlation of potassium channel sensing and nitric oxide activity in neuroinflammation
摘要
Neuroinflammation, a vital protective response for tissue homeostasis, becomes a detrimental force when chronic and dysregulated, driving neurological disorders like Alzheimer’s, Parkinson’s, and Huntington’s diseases. Potassium (K+) channels maintain membrane potential and cellular excitability in neurons and glia within the intricate CNS signaling network. Neuronal injury or inflammation can disrupt K+ channel activity, leading to hyperexcitability and chronic pain. Adding another layer of complexity is nitric oxide (NO), a short-lived gaseous molecule with dual roles in the CNS. While physiologically modulating synaptic plasticity and vascular control, NO also acts pathologically in neuroinflammation and neurodegenerative diseases, making it a “double-edged sword.” Understanding the precise molecular mechanisms underpinning neuroinflammation in neurological diseases is crucial for developing effective treatments. This review aims to elucidate the therapeutic potential and identify areas for further investigation by synthesizing a decade of research on the relationship between K+ channel sensing and the NO signaling pathway in neuroinflammation.
