Receptors made visible: The described biotin-tagged small-molecule probes with excellent affinities for the CB(1) and CB(2) cannabinoid receptors (CB(1)R and CB(2)R) enable direct visualization of these receptors in native cellular systems, including neurons, microglia, and immune cells. This method could overcome some of the limitations of current methodologies and may help to dissect the complexity of the endogenous cannabinoid system.

Methamphetamine (METH) is a highly addictive psychostimulant, and despite its widespread abuse, there are no FDA-approved treatments for METH use disorder (MUD). Cannabidiol (CBD), a non-psychoactive cannabinoid, has shown promise in reducing behaviors linked to psychostimulant use, including METH. However, the underlying neurobiological mechanisms remain unclear.

Exogenous cannabinoids have long been known to promote eating. However, the underlying mechanisms have not been completely elucidated, which is critical to understanding their utility. The orexin/hypocretin (OH) system of the lateral hypothalamus (LHA) has known anatomical, biochemical, and physiological interactions with the endocannabinoid system, and has an established role in promoting appetitive behavior; yet, it is still unknown if the OH system mediates food intake following cannabinoid administration.

Background: Burning Mouth Syndrome (BMS) is an idiopathic condition characterised by chronic oral burning pain without clinically evident lesions. Despite its prevalence and impact on quality of life, the pathophysiology of BMS remains poorly understood, limiting diagnostic and therapeutic options.
Objective: To systematically review histological, morphological and cytological changes in oral tissues of BMS patients, with a focus on epithelial cells and nerve fibres, to identify potential biomarkers and inform future research directions.

Despite effective antiretroviral therapy (ART), people with HIV (PWH) experience persistent inflammation and metabolic dysfunction, increasing their risk for non-AIDS comorbidities. Accordingly, we evaluated the effects of long-term/low-dose Δ-tetrahydrocannabinol (THC) supplementation in simian immunodeficiency virus (SIV)-infected, ART-treated rhesus macaques (RMs). THC significantly increased plasma/jejunum serotonin and indole-3-propionate, enhancing gut-brain communication through up-regulation of serotonin receptors (HTR4/HTR7) and aryl hydrocarbon receptor (Ahr) signaling via a cannabinoid receptor (CBR)-2-mediated mechanism.
