Current neurophysiological evidence supports the existence of dedicated pruriceptor neurons and distinct molecular pathways that separate the transmission of itch from that of pain.

The analysis

The retrieved literature consistently supports the concept that itch is mediated by specialized pruriceptors and distinct signaling pathways separate from general pain mechanisms, as demonstrated by specific receptor and channel involvement.
