Objective:  To determine the neural mechanism promoting the itch-scratching cycle.
Summary:  Ablation of Tac1+ but not SST+ neurons decreases itch-induced scratching behavior.  l/vlPAG Tac1+ neurons Induce Scratching Behavior via a Descending Pathway.
Dose:  To ablate the spinal GRPR+ neurons, mice were intrathecally injected with Bombesin-SAP or Control Blank-SAP (400 ng/5 mL).

Objective:  To determine the role of somatostatin in itch and pain.
Summary:  Results define the neural circuit underlying somatostatin-induced itch and characterize a contrasting antinociceptive role for the peptide.
Dose:  Ablation of Npr1- and GRPR-expressing spinal cord interneurons was accomplished by intrathecal (segment L3/4) injection of Nppb-SAP (4 μg/10 μL) and Bombesin-SAP (2.5 μg) respectively.
