Glioblastoma is the most aggressive brain cancer in humans with very poor prognosis and high mortality rate. Despite advances in treatment, glioblastoma almost always recurs and new therapeutic methods are urgently needed. This study aimed at assessing the cytotoxic and antiproliferative effects of AM 1172 and cannabidiol (two cannabinoid receptor ligands) in vitro, when used alone and in combination with cisplatin (a standard cytotoxic drug), in various human neuroblastoma (CHP-134, KELLY), human glioblastoma (U-87MG and T98G) and rat glioblastoma (C6) cell lines.

G protein-coupled receptors (GPCRs) adopt conformational states that activate or inhibit distinct signaling pathways, including those mediated by G proteins or β-arrestins. Biased signaling through GPCRs may offer a promising strategy to enhance therapeutic efficacy while reducing adverse effects. Cannabinoid receptor 1 (CB1), a key GPCR in the endocannabinoid system, presents therapeutic potential for conditions such as pain, anxiety, cognitive impairment, psychiatric disorders, and metabolic diseases.

The endocannabinoid system's significance in maintaining blood-brain barrier (BBB) integrity under physiological and pathological conditions is suggested by several reports, but the underlying molecular mechanisms are not well understood. In this paper, we investigated the effects of depletion of 2-arachidonoylglycerol (2-AG), one of the main endocannabinoids in the central nervous system, on BBB integrity using pharmacological tools. Female Sprague-Dawley rats were injected with the diacylglycerol lipase α (DAGLα) inhibitor LEI-106 (40 mg/kg, i.

In addition to the known therapeutic indications for cannabidiol, its administration by inhalation appears to be of great interest. Indeed, there is evidence of cannabidiol's efficacy in several physiological pathways, suggesting its potential for a wide range of applications for both local and systemic pulmonary administration like cancers. Significant advances in pulmonary drug delivery have led to innovative strategies to address the challenges of increasing the respirable fraction of drugs and standardizing inhalable products.

This study explores the therapeutic potential of targeting fatty acid amide hydrolase (FAAH), the major enzyme degrading AEA, in mouse models of amyloidosis (APP/PS1 and Tg2576). Enhancing AEA signaling by genetic deletion of FAAH delayed cognitive deficits in APP/PS1 mice and improved cognitive symptoms in 12-month-old AD-like mice.
