Cytotoxic Effects of Cannabidiol on Neonatal Rat Cortical Neurons and Astrocytes: Potential Danger to Brain Development.

The influence of cannabidiol (CBD) on brain development is inadequately understood. Since CBD is considered a non-intoxicating drug, it has attracted great interest concerning its potential medical applicability, including in pregnant women and children. Here, we elucidated the response of perinatal rat cortical neurons and astrocytes to CBD at submicromolar (0.

A regulatory take on cannabis and cannabinoids for medicinal use in the European Union.

The discovery of the endocannabinoid system has raised public interest in the medicinal use of cannabis, phytocannabinoids, and synthetic cannabinoids, which has always been closely regulated due to their psychotropic effects and potential abuse. The review takes a quick look at the current legal framework in the European Union, which regulates cannabis use and cultivation for medicinal purposes in line with the United Nations Conventions on the production, trade, and use of cannabis, phytocannabinoids, and synthetic cannabinoids. And while the EU legislation precisely defines requirements and marketing authorisation procedures for medicinal products for all EU member states, there is no common regulatory framework for magistral and officinal preparations containing cannabinoids, as they are exempt from marketing authorisation.

NADPH oxidase inhibitor VAS2870 prevents staurosporine-induced cell death in rat astrocytes.

Background Astrocytes maintain central nerve system homeostasis and are relatively resistant to cell death. Dysfunction of cell death mechanisms may underlie glioblastoma genesis and resistance to cancer therapy; therefore more detailed understanding of astrocytic death modalities is needed in order to design effective therapy. The purpose of this study was to determine the effect of VAS2870, a pan-NADPH oxidase inhibitor, on staurosporine-induced cell death in astrocytes.

Histamine and astrocyte function.

Astrocytes support the brain through numerous functional interactions in health and disease. The recent advances in our knowledge of astrocyte involvement in various neurological disorders raised up several questions about their role and functioning in the central nervous system. From the evidence discussed in this review, we show that histamine importantly influences the main astrocytic activities such as ion homeostasis, energy metabolism, neurotransmitter clearance, neurotrophic activity and immune response.
