Liu X, Wang Y, Tao T, Zeng L, Wang D, Wen Y, Li Y, Zhao Z, Tao A (2021) GRPR/extracellular signal-regulated kinase and NPRA/extracellular signal-regulated kinase signaling pathways play a critical role in spinal transmission of chronic itch. J Invest Dermatol 141(4):863-873. doi: 10.1016/j.jid.2020.09.008
Summary: This study investigates whether there are certain key signaling molecules downstream of the recently identified peptides mediating itch in the spinal cord. Bombesin-SAP completely abolished extracellular signal-regulated kinase (ERK) activation. ERK was the most highly activated by their agonists BNP (Nppb, brain-derived natriuretic peptide) and octreotide. Nppb-SAP only partially reduced pERK in cervical spinal cord.
