电压门控性钾通道维持神经元静息膜电位,参与细胞兴奋性的改变。在三叉神经痛发病过程中,三叉神经节神经元作为初级感觉神经元,在痛觉的传导和传递过程中起重要作用。电压门控性钾通道的多种类型在三叉神经节神经元中均有表达,激活时产生不同类型的钾电流。电压门控性钾通道功能的改变,及其与多种神经递质、炎性介质和受体间的相互作用,在三叉神经痛的发病过程中起到了重要作用。
Voltage-gated potassium channels regulate cell membrane potential and excitability in neurons. Trigeminal ganglion as a primary sensory neuron plays an important role in the pain transduction and transmission of trigeminal neuralgia. Trigeminal ganglion neurons express many subtypes of voltage-gated potassium channels and they can evoke different type of K+ current when activated. The alteration of voltage-gated potassium channels and their interaction with neurotransmitters, inflammatory cytokines and receptors play important roles in the development of trigeminal neuralgia.
