D. Julius was awarded the 2021 Medicine Nobel prize for the discovery of new cationic channels that detect temperatures either over 40 °C (TRPV1) or cold (TRPM8) ranging from 8-15 °C, followed by the latter identification of other channels that sense temperatures within other ranges. On the other hand, A. Patapoutian shared the 2021 Nobel prize for the independent and simultaneous co-discovery of the TRPM8 cationic channel. Furthermore, Patapoutian iden-tified piezo 1 and 2 channels previously referred to as the cell mechanosensors related to the sense of touch and proprioception. These experimental findings indicate that these novel cationic channels localized in nerve endings of the skin, mouth, lips, bronchial tree, the nephron, plus a variety of tissues transduce phy-sical stimuli into electrical activity that reach the brain sensory cortex to process these stimuli and elicit animal behavior.
大卫·朱利叶斯因发现能检测高于40°C(TRPV1)或8至15°C低温(TRPM8)的新型阳离子通道而被授予2021年诺贝尔医学奖,随后又鉴定出了其他能感知其他温度范围的通道。另一方面,阿登·帕塔普蒂安因独立且同时共同发现TRPM8阳离子通道而分享了2021年诺贝尔奖。此外,帕塔普蒂安还鉴定出了压电1和压电2通道,它们之前被称为与触觉和本体感觉相关的细胞机械传感器。这些实验结果表明,这些位于皮肤、口腔、嘴唇、支气管树、肾单位以及各种组织神经末梢的新型阳离子通道,将物理刺激转化为电活动,传至大脑感觉皮层以处理这些刺激并引发动物行为。
