Use of Non-psychoactive cannabinoids in the treatment of neurodegenerative diseases

16.09.2008
Scientists at the Complutense University of Madrid (UCM) have studied the effects of a drug that reduces the progression of a disease similar to Multiple sclerosis in animals. This discovery represents another step in the standing fight against the disease.

The research, published in the prestigious Journal of Biological Chemistry, aimed to study in depth the already known effects of lessening the symptoms and stopping the advance of multiple sclerosis that cannabinoids have, while developing a drug that would not have the psychoactive effects of the marijuana plant (Cannabis sativa).

To achieve this, the scientists have focused their study on the role of the cannabinoids receptor CB2, present both in the immune system as well as in the defence-cells of the nervous system (microglial cells).

Multiple sclerosis is a neurodegenerative disease whose causes are not yet fully understood. It is known that the disease is produced by an autoimmune response where the defence-cells in the organism attack and destroy the nerve cells of the organism generating symptoms such as stiffness, twitching, progressive paralysis, etc.

The researchers managed by Professor Ismael Galve from the UCM, founded their conclusions on the role of the cannabinoids receptors in Experimental autoimmune encephalomyelitis, a disease that reproduces some of the proceses and symptoms of multiple sclerosis. In the study it has been tested that administering a drug that activates receptor CB2 (but not CB1, responsible for the psicoactive effects), the sysmptopms of the disease lessen and a reduction of 50% in nerve cell loss was perceived.

This research has introduced yet another novelty: The stimulation of the CB2 receptor not only reduces the excesive activation of brain cells in charge of the defence of the central nervous system, but it allso reduces the supply of new defence-cells that travelling throught the blood stream from bone marrow, would act as reinforcements for the defence-cells of the central nervous system.

According to Ismael Galve, the results are important because the drug is capable of acting in an already sick animal, reducing the symptoms and the brain cell loss. The obtained results, along with other predecessors confirm the role of endogenous cannabinoids in the origin of experimental autoimmune encephalomyelitis and its possible application to multiple esclerosis. Therefore the role of the CB2 receptor in the regulation and neuro-inmune response supports the research currently being carried out on the possible use of cannabinoid drugs in the treatment of neurodegenerative diseases.

The research has been carried out by the department of biochemistry and molecular biology of the Complutense University of Madrid, in collaboration with the Neuroscience research Institute of Lyon in France and the pharmaceutical company Pharmos.

Im Focus: Superconducting vortices quantize ordinary metal

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.

These fundamental results, published in the journal Nature Communications, enable a better understanding and description of the processes occurring at the...

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
