在病理条件下发生的酸中毒不仅影响细胞内信号分子,而且直接激活配体门控离子通道的独特家族:酸敏感离子通道(ASIC)。ASIC在整个中枢和外周神经系统中广泛表达,并在疼痛感觉、学习和记忆以及恐惧条件反射中发挥作用。ASIC的过度激活导致神经变性疾病,例如缺血性脑/脊髓损伤、多发性硬化、帕金森病和亨廷顿病。因此,靶向ASIC可能是这些疾病的潜在治疗策略。本文主要综述了ASIC的电生理学和药理学以及ASIC在神经元毒性中的作用。
Acidosis that occurs under pathological conditions not only affects intracellular signaling molecules, but also directly activates a unique family of ligand-gated ion channels: acid-sensing ion channels (ASICs). ASICs are widely expressed throughout the central and peripheral nervous systems and play roles in pain sensation, learning and memory, and fear conditioning. Overactivation of ASICs contributes to neurodegenerative diseases such as ischemic brain/spinal cord injury, multiple sclerosis, Parkinson’s disease, and Huntington’s disease. Thus, targeting ASICs might be a potential therapeutic strategy for these conditions. This mini-review focuses on the electrophysiology and pharmacology of ASICs and roles of ASICs in neuronal toxicity.
