Promising multiple sclerosis treatment targets immune cells to increase neuroprotection, study shows

Posted: 06 Dec 2011 05:29 AM PST

Laquinimod is an orally available synthetic compound that has been successfully evaluated in phase II/III clinical studies for the treatment of relapsing-remitting multiple sclerosis. The mechanism of action of laquinimod has not been fully elucidated, but a new study suggests that laquinimod triggers immune cells within the central nervous system to produce and release brain-derived neurotrophic factor, contributing to the repair or survival of neurons and thus limiting brain damage.

Oxidative stress: Less harmful than suspected?

Posted: 05 Dec 2011 07:26 AM PST

Oxidative stress is considered to be involved in a multitude of pathogenic processes and is also implicated in the process of aging. For the first time, scientists have been able to directly observe oxidative changes in a living organism. Their findings in fruit flies raise doubts about the validity of some widely held hypotheses: The research team has found no evidence that the life span is limited by the production of harmful oxidants.
