Researchers working on the development of drugs to limit neuronal death

Neurons die en masse when the spinal cord is injured or when a person suffers a stroke. Researchers of the Max Delbrueck Center for Molecular Medicine (MDC) Berlin-Buch, Germany, and of Aarhus University, Denmark, have unraveled the molecular mechanism which causes the death not only of damaged neurons, but also of healthy nerve cells.

How does the opioid system work?

The opioid system controls pain, reward and addictive behaviors. Opioids exert their pharmacological actions through three opioid receptors, mu, delta and kappa whose genes have been cloned (Oprm, Oprd1 and Oprk1, respectively).

Relatives of patients with Parkinson's disease may have an increased risk of developing dementia

Parkinson's disease is characterized by a decline in the functions of the central nervous system, such as motor skills and speech. Several studies have shown an increased risk of dementia in first-degree relatives of Parkinson's disease patients, while other studies have not confirmed the association, according to background information in the article.
