Bursting Enables GRP Neurons to Engage Spinal Itch Circuits

WebCentral CQ itch occurs via gastrin-related peptide (GRP) and its receptor (GRPR) in the dorsal spinothalamic tracts, as well as glutamic mediated GRP projection to parabrachial nucleus. The possibility of chronic itch therapy based on personalized medicine, genetics, and transcriptomics or the use of itch "polypill/polycream" are discussed. WebFeb 16, 2024 · According to previous reports in the spinal cord, the GRP/GRPR system participates in the regulation of itch-specific transmission rather than the transmission of pain.
