Mediation of movement-induced breakthrough cancer pain by IB4-binding nociceptors in rats.

Havelin J, Imbert I, Sukhtankar D, Remeniuk B, Pelletier I, Gentry J, Okun A, Tiutan T, Porreca F, King T (2017) Mediation of movement-induced breakthrough cancer pain by IB4-binding nociceptors in rats. J Neurosci 37:5111-5122.. doi: 10.1523/JNEUROSCI.1212-16.2017

Objective: To define a novel preclinical measure of movement-induced breakthrough pain (BTP) that is observed in the presence of morphine controlling ongoing pain.

Summary: Novel compounds targeting IB4-binding nociceptors may improve pain management for cancer pain patients and other patient populations suffering from BTP that is inadequately treated by currently available medications.

Usage: To determine the effect of eliminating input from IB4-binding fibers, separate groups of rats received spinal administration of IB4-SAP or the control, Blank-SAP (3.2 mcg/20 mcl saline) followed by a 10 mcl flush of saline. Movement of an air bubble placed between drug solution and saline was used to monitor progress of the injection.
