CB1 is one of the two cannabinoid receptors that are involved in the effects seen in the CNS by users of marijuana. Different agonists and antagonists have helped in the development of new strategies for the treatment of pain, obesity, neurological diseases including multiple sclerosis, emotional disturbances such as anxiety and other psychiatric disorders including drug and alcohol addiction. The CB1 receptor is densely distributed in areas of the brain related to motor control, cognition, emotional responses, motivated behavior, and homeostasis. 

This targeted toxin recognizes cells that express human and rat cannabinoid receptor 1 (CB1). Anti-CB1-SAP is a bonded toxin between a biotinylated affinity-purified rabbit polyclonal antibody to cannabinoid receptor 1 (CB1) and the secondary conjugate Streptavidin-ZAP containing the ribosome-inactivating protein, saporin.

Anti-CB1-SAP is available individually (Cat. #IT-104) or as a kit (Cat. #KIT-104) which includes Anti-CB1-SAP and BIgG-SAP rabbit (Cat. #IT-75).

CB1 receptors on a subset of vagal afferent neurons modulate voluntary ethanol intake in mice

Herrerias A, Oliverio A, Dvorácskó S, Thyagarajan A, Chedester L, Liu J, Cinar R, Iyer MR, Kunos G, Godlewski G (2025) CB1 receptors on a subset of vagal afferent neurons modulate voluntary ethanol intake in mice. Mol Psychiatry doi: 10.1038/s41380-025-03266-9 PMID: 40975751

Objective: To investigate how peripheral CB1 receptors on vagal afferent neurons regulate voluntary ethanol intake and their role in gut-brain signaling underlying alcohol consumption.

Summary: Selective deletion or ablation of CB1R in nodose ganglion neurons abolished the inhibitory effects of peripheral CB1R antagonists on voluntary ethanol intake. The study identifies CB1R on Gpr65⁺ vagal sensory neurons as critical mediators of gut-brain communication regulating alcohol preference and intake.

Usage: Anti-CB1-SAP (IT-104) or Blank-SAP (IT-21) was injected into the proximity of the nodose ganglion at 250 ng/mL to selectively ablate CB1R-expressing vagal afferent neurons
