Inhibiting endocytosis in CGRP+ nociceptors attenuates inflammatory pain-like behavior
Abstract
The authors show the endocytotic adaptor subunit called AP2A2 is differentially expressed in CGRP+ nociceptors. Locally inhibiting nociceptor endocytosis with a lipidated AP2 inhibitor peptide reduces acute and chronic pain-like behaviour in mice and rats, indicating prolonged analgesia.
