The investigation proves the role of the ionic channel in the pain perception by formaldehyde application. Pain does not necessarily equal tissue damage which might e.g. require further neurogenic inflammation. The latter response recruits e.g. the immunocompetent cells and incites growth factor upregulation. The major mediator in this process is substance P as liberated from its inactive precursors. Its effects can be counteracted by the upregulation of the dipeptidylpeptidase IV (1). Thus, it seems that the pain perception is associated with a sensory peptidergic hyperfunction that initiates the inflammatory response. It would be very interesting to probe this association further.
