Chronic musculoskeletal pain is debilitating and affects ∼ 20% of adults. Tissue acidosis is present in painful musculoskeletal diseases like rheumatoid arthritis. ASICs are located on skeletal muscle and joint nociceptors as well as on nonneuronal cells in the muscles and joints, where they mediate nociception. This review discusses the properties of different types of ASICs, factors affecting their pH sensitivity, and their role in musculoskeletal hyperalgesia and inflammation.
慢性肌肉骨骼疼痛使人虚弱,影响约20%的成年人。在类风湿关节炎等疼痛性肌肉骨骼疾病中存在组织酸中毒。酸敏感离子通道(ASICs)位于骨骼肌和关节伤害感受器以及肌肉和关节中的非神经元细胞上,在这些部位它们介导痛觉。本文综述了不同类型ASICs的特性、影响其pH敏感性的因素,以及它们在肌肉骨骼痛觉过敏和炎症中的作用。
