LSUSHC research identifies new experimental drug for stroke

Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, has found that a synthetic molecule protected the brain in a model of experimental stroke.

Dr. Bazan was issued a patent on the molecule called LAU-0901, a low molecular weight drug that crosses the blood-brain barrier. The findings are published in the March 2012 issue of Translational Stroke Research.

During an ischemic stroke, the most common kind, the body releases signals that cause neuroinflammation which leads to a buildup of chemicals that harm the brain. Platelet-activating factor (PAF) accumulates, and inhibition of this process plays a critical role in neuronal survival.

"LAU-0901 is able to reduce this incorrect signaling and inhibit the PAF receptor, which reduces multiple neuroinflammatory signals and greatly lessens the severity of damage in experimental stroke," notes Dr. Bazan.

The research team used magnetic resonance imaging in conjunction with behavior and immunohistopathology to further study this novel therapeutic approach. The researchers report that LAU-0901, given two hours after the onset of experimental stroke, lessened the severity of brain damage, significantly reduced lesions in the brain, and improved coordination and movement. LAU-0901 produced no discernible side effects. These findings suggest LAU-0901 is a promising neuroprotectant that provides the basis for future therapeutics in patients suffering ischemic stroke.

Stroke is a leading cause of death and disability worldwide. Conventional therapies for ischemic stroke include thrombolytic therapy, prevention of inappropriate coagulation and thrombosis, and surgery to repair vascular abnormalities.Only one FDA-approved therapy exists for treatment of acute ischemic stroke, the thrombolytic tissue plasminogen activator (tPA), but only 5% of all ischemic stroke patients are eligible for treatment with tPA.

The research team also included Professor Ludmila Belayev and MD/PhD student Tiffany Niemoller Eady at LSU Health Sciences Center New Orleans, as well as Dr. Julio Alvarez Builla and other scientists from the University of Alcala, Spain, and Dr. Andre Obenaus at the University of Loma Linda.

The research was supported by grants from the National Institute of Neurological Disorders and Stroke and the National Institute on Aging of the National Institutes of Health.

Im Focus: How Cells in the Developing Ear ‘Practice’ Hearing

Before the fluid of the middle ear drains and sound waves penetrate for the first time, the inner ear cells of newborn rodents practice for their big debut. Researchers at Johns Hopkins report they have figured out the molecular chain of events that enables the cells to make “sounds” on their own, essentially “practicing” their ability to process sounds in the world around them.

The researchers, who describe their experiments in the Dec. 3 edition of the journal Cell, show how hair cells in the inner ear can be activated in the absence...

Im Focus: Lactate for Brain Energy

Nerve cells cover their high energy demand with glucose and lactate. Scientists of the University of Zurich now provide new support for this. They show for the first time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis.

In comparison to other organs, the human brain has the highest energy requirements. The supply of energy for nerve cells and the particular role of lactic acid...
