The ability of the body to perceive noxious stimuli lies in a heterogeneous group of primary somatosensory neurons termed nociceptors. The molecular receptors of noxious mechanical, temperature, or chemical stimuli are expressed in these neurons and have drawn considerable attention as possible targets for analgesic development to improve treatment for the millions who suffer from chronic pain conditions. A number of thermoTRPs, a subset of the transient receptor potential family of ion channels, are activated by a wide range on noxious stimuli. In this review, we review the function of these channels and examine the evidence that thermoTRPs play a vital role in acute, inflammatory and neuropathic nociception.
身体感知有害刺激的能力在于一类异质性的初级躯体感觉神经元,即伤害感受器。有害的机械、温度或化学刺激的分子受体在这些神经元中表达,并作为镇痛药物开发的潜在靶点受到了广泛关注,有望改善数百万慢性疼痛患者的治疗。许多热激活瞬时受体电位通道(thermoTRPs),即离子通道瞬时受体电位家族的一个亚群,可被多种有害刺激激活。在本综述中,我们回顾了这些通道的功能,并研究了热激活瞬时受体电位通道在急性、炎症性和神经性疼痛感受中起关键作用的证据。
