Endocannabinoid system and cannabinoids in neurogenesis – new opportunities for neurological treatment? Reports from experimental studies.

“Neurogenesis is one of the most important phenomenona affecting human life. This process consists of proliferation, migration and differentiation of neuroblasts and synaptic integrations of newborn neurons.
Proliferation of new cells continues into old age, also in humans, although the most extensive process of cell formation occurs during the prenatal period. It is possible to distinguish two regions in the brain responsible for neurogenesis: the dentate gyrus (DG) of the hippocampus and the sub-ventricular zone (SVZ). Hippocampal neurogenesis is very sensitive to various physiological and pathological stimuli.
The functional integration of the newly-born dentate granule cells into hippocampal circuitry, and their ability to mediate long-term potentiation in DG, has led to the hypothesis that neurogenesis in the adult brain may play a key role in learning and memory function, as well as cognitive dysfunction in some diseases.
Brain disorders, such as neurodegenerative diseases or traumatic brain injuries, significantly affect migration, proliferation and differentiation of neural cells. In searching for the best neurological drugs protecting neuronal cells, stimulating neurogenesis, while also developing no side-effects, endocannabinoids proved to be a strong group of substances having many beneficial properties.
Therefore, the latest data is reviewed of the various experimental studies concerning the analysis of the most commonly studied cannabinoids and their impact on neurogenesis.”
