Endocannabinoid signaling in glioma

High‐grade gliomas constitute the most frequent and aggressive form of primary brain cancer in adults. These tumors express cannabinoid CB(1) and CB(2) receptors, as well as other elements of the endocannabinoid system.

Sumario:High‐grade gliomas constitute the most frequent and aggressive form of primary brain cancer in adults. These tumors express cannabinoid CB(1) and CB(2) receptors, as well as other elements of the endocannabinoid system. Accruing preclinical evidence supports that pharmacological activation of cannabinoid receptors located on glioma cells exerts overt anti‐tumoral effects by modulating key intracellular signaling pathways. The mechanism of this cannabinoid receptor‐evoked anti‐tumoral activity in experimental models of glioma is intricate and may involve an inhibition not only of cancer cell survival/proliferation, but also of invasiveness, angiogenesis, and the stem cell‐like properties of cancer cells, thereby affecting the complex tumor microenvironment. However, the precise biological role of the endocannabinoid system in the generation and progression of glioma seems very context‐dependent and remains largely unknown. Increasing our basic knowledge on how (endo)cannabinoids act on glioma cells could help to optimize experimental cannabinoid‐based anti‐tumoral therapies, as well as the preliminary clinical testing that is currently underway.
