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.

Gulino R, Parenti R, Gulisano M (2017) Sonic hedgehog and TDP-43 participate in the spontaneous locomotor recovery in a mouse model of spinal motoneuron disease. J Funct Morphol Kinesiol 2:11.. doi: 10.3390/jfmk2020011

Summary: The authors used a mouse model of neurotoxic motoneuron depletion to study the role of Sonic hedgehog and TDP-43 in the compensatory changes occurring after the lesion. The injection of cholera toxin-B saporin (CTB-SAP; Cat. #IT-14) into the gastrocnemius muscle caused a partial motoneuron death accompanied by an impairment of locomotion.  Motor activity was significantly restored as soon as one month later.

Objective: To investigate how the dorsal raphe nucleus (DRN) and superior colliculus work in concert to extract and translate visual threats into defensive behavioural responses.

Summary: A dedicated population of RGCs signals rapidly approaching visual threats and their input to the DRN controls a serotonergic self-gating mechanism that regulates innate defensive responses.

Usage: Mice received bilateral intraocular injection (2 μg per eye) made between Streptavidin-Saporin and a biotinylated CTB antibody, or Anti-Melanopsin-SAP (2 μg per eye). For detection of melanopsin, retinas were incubated for 3 days at 4 °C with anti-melanopsin (1:600).

Summary: The authors discuss their work with Dermorphin-SAP (Cat. #IT-12) and their demonstration that damage of RMTg MOR-expressing GABAergic neurons by Dermorphin-SAP increased the intake and preference for alcohol, boosted the expression and slowed down the extinction of alcohol conditioned place preference, and increased locomotion. Microinjection of DS into the RMTg substantially reduced the number of RMTg cells. Importantly, the rats that received DS injection elevated their alcohol intake and preference compared to those that received an injection of Blank-SAP (Cat. #IT-21), which did not cause neuronal damage.
