躯体感觉系统传递许多信号,从轻微的触摸到疼痛和瘙痒。触摸对空间意识和交流至关重要。然而,在疾病状态下,无害的机械刺激可引起病理性感觉,如机械性瘙痒(感觉异常)。控制这种转化的分子和细胞机制仍然未知。我们发现,在小鼠中,老化和干燥皮肤的变感与皮肤中的触觉感受器默克尔细胞的损失有关。皮肤中默克尔细胞和相关机械敏感性Piezo 2通道的靶向遗传缺失足以产生变感。默克尔细胞的化学发生激活可防止干燥皮肤的变应性。这项研究揭示了一个以前未知的功能,皮肤触觉感受器,并可能提供深入了解的发展变感。
The somatosensory system relays many signals ranging from light touch to pain and itch.Touch is critical to spatial awareness and communication. However, in disease states, innocuous mechanical stimuli can provoke pathologic sensations such as mechanical itch (alloknesis). The molecular and cellular mechanisms that govern this conversion remain unknown. We found that in mice, alloknesis in aging and dry skin is associated with a loss of Merkel cells, the touch receptors in the skin. Targeted genetic deletion of Merkel cells and associated mechanosensitive Piezo2 channels in the skin was sufficient to produce alloknesis. Chemogenetic activation of Merkel cells protected against alloknesis in dry skin. This study reveals a previously unknown function of the cutaneous touch receptors and may provide insight into the development of alloknesis.
