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 …
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.
