KIT-28:  NPY-SAP, Blank-SAP
Objective:  To test the relevance of the NPYY1 spinal population to the development and/or maintenance of acute and neuropathic pain.
Summary:  This neuroanatomical and behavioral characterization of Y1R-expressing excitatory interneurons provides compelling evidence for the development of spinally-directed  Y1R agonists to reduce chronic neuropathic pain.
Dose:  Selectively ablated Y1R-expressing interneurons while sparing the central terminals of primary afferents.  Rats received intrathecal injections of either NPY-SAP or Control Blank-SAP (1000 ng each).

Summary:  NPY is released from dorsal horn interneurons or primary afferent terminals by electrical stimulation and by activation of TRPV1, PKA or NMDA receptors in. Release evoked by noxious and tactile stimuli increases after peripheral nerve injury.
Referenced “Ablation of Y1-expressing dorsal horn neurons with NPY-saporin produced antinociception (Lemons and Wiley, 2012) and reduced mechanical and cold hypersensitivity in the spared nerve injury model (Nelson et al., 2019), suggesting that they are pro-nociceptive neurons.”
