IB4-SAP to study mechanical hyperalgesia

To determine which subtype of nociceptor, peptidergic or non-peptidergic, is involved in the mechanical hyperalgesia induced by LMWH (low molecular weight hyaluronan), rats were pretreated with neurotoxins previously shown to selectively deplete these two types of sensory neurons:  Isolectin B4 (IB4)-saporin (SAP), which acts on IB4-positive, non-peptidergic neurons (Cat. #IT-10 IB4-SAP), and substance P-saporin (Cat. […]

Neuromedin B and Itch

To examine the role of NMBR+ dorsal horn neurons in itch and pain transmission, the authors treated mice with NMB-SAP (Cat. #IT-70; 2–3 μg, i.t.) at which no side effects were observed. NMB-SAP treated mice barely showed scratching behaviors, whereas control mice exhibited NMB-induced scratching with a rapid onset of scratching responses. These data demonstrate […]

Poster Award goes to Orexin-B

Since 2000, Advanced Targeting Systems has presented an award each year at the Society for Neuroscience meeting for the best Poster of the Year using ATS targeting tools. This year the competition was fierce and some very exciting science was presented. Also, a big congratulations to the winner of the drawing for a $500 product […]

Better Gene Therapy Through Targeting

Gene therapy has been proposed for a variety of genetic disorders, including severe combined immunodeficiency, but it has not yet found routine use in the clinic, in part because of potential complications. To help pave the way for safer translation of such gene therapy, Schiroli et al. studied potential approaches to gene therapy in mouse […]

Noradrenaline production reduced after treatment with Anti-DBH-SAP

Changes in the Secretory Activity of Organs Producing Noradrenaline Upon Inhibition of Its Synthesis in Neonatal Rat Brain. Murtazina, AR, Dilmukhametova, LK, Nikishina, YO, Sapronova, AY, Volina, EV, & Ugrumov, MV. (2017). Russian Journal of Developmental Biology, 48 (5):295-300. This study demonstrates that synthesis of noradrenaline after destruction of noradrenergic neurons was switched off by stereotactically […]

Visualizing Retinal Ganglion Cells with Anti-Melanopsin

3D Visualization of Individual Regenerating Retinal Ganglion Cell Axons Reveals Surprisingly Complex Growth Paths. Bray, ER, Noga, M, Thakor, K, et al. (2017). eNeuro DOI. PMID: 28856242 “Our study demonstrates extensive and circuitous RGC axon elongation both in pre- and post-lesion regions, highlighting the need to better understand the factors that inhibit direct axon growth in […]

Got an itch? Bombesin-SAP may help

Itch Induces Conditioned Place Aversion in Mice. Mu, D, & Sun, Y-G. (2017). Neuroscience Letters, http://dx.doi.org/10.1016/j.neulet.2017.08.046 “Consistently, ablation of itch‐specific neurons that express gastrin‐releasing peptide receptor in the spinal cord also abolished itch‐induced Conditioned Place Aversion (CPA), confirming that itch‐induced CPA is dependent on the spinal itch circuit.” Mice were given a single intrathecal injection […]
