Identification of a spinal circuit for mechanical and persistent spontaneous itch.

Pan H, Fatima M, Li A, Lee H, Cai W, Horwitz L, Hor CC, Zaher N, Cin M, Slade H, Huang T, Xu XZS, Duan B (2019) Identification of a spinal circuit for mechanical and persistent spontaneous itch. Neuron 103(6):1135-1149.e6. doi: 10.1016/j.neuron.2019.06.016

Objective: To identify a spinal circuit for mechanical and persistent spontaneous itch.

Summary: Findings indicate excitatory interneurons expressing Urocortin 3::Cre (Ucn3+) in the dorsal spinal cord as a valid cellular target for future therapeutic interventions against chronic itch, without affecting normal touch.

Usage: To ablate spinal GRPR+ neurons, mice were given a single intrathecal injection of either Bombesin-SAP or Blank-SAP (400 ng in 10 mL sterile saline). To ablate spinal Npra+ neurons, mice were given a single intrathecal injection of either Nppb-SAP or Blank-SAP (5 mg in 10 mL sterile saline).

Related Products: Bombesin-SAP (Cat. #IT-40), Nppb-SAP (Cat. #IT-69), Blank-SAP (Cat. #IT-21)
