触觉是基本的,因为它提供了有关我们物理环境性质的重要信息。初级感觉神经元提供了这种感觉在外周的基础,然而,最近的工作表明,触摸转导机制也发生在上游的感觉神经元通过非神经元细胞,如默克尔细胞和角质形成细胞。在脊髓内,深背角回路集中传递无害的触摸,并在受伤时将触摸转化为疼痛。在此,非神经元细胞在持续性机械性疼痛的诱导和维持中起关键作用。这篇综述强调了我们对机械感觉的理解的最新进展,包括对非神经元细胞在触觉和疼痛中的作用的日益认识。
The sense of touch is fundamental as it provides vital, moment-to-moment information about the nature of our physical environment. Primary sensory neurons provide the basis for this sensation in the periphery; however, recent work demonstrates that touch transduction mechanisms also occur upstream of the sensory neurons via non-neuronal cells such as Merkel cells and keratinocytes. Within the spinal cord, deep dorsal horn circuits transmit innocuous touch centrally and also transform touch into pain in the setting of injury. Here non-neuronal cells play a key role in the induction and maintenance of persistent mechanical pain. This review highlights recent advances in our understanding of mechanosensation, including a growing appreciation for the role of non-neuronal cells in both touch and pain.
