Research sheds new light on traumatic brain injuries

Even a mild injury to the brain can have long lasting consequences, including increased risk of cognitive impairment later in life.

While it is not yet known how brain injury increases risk for dementia, there are indications that chronic, long-lasting, inflammation in the brain may be important. A new paper by researchers at the University of Kentucky Sanders-Brown Center on Aging (SBCoA), appearing in the Journal of Neuroscience, offers the latest information concerning a "switch" that turns "on" and "off" inflammation in the brain after trauma.

A team of researchers led by Linda Van Eldik, director of SBCoA, used a mouse model to study the role of p38a MAPK in trauma-induced injury responses in the microglia resident immune cell of the brain.

"The p38á MAPK protein is an important switch that drives abnormal inflammatory responses in peripheral tissue inflammatory disorders, including chronic debilitating diseases like rheumatoid arthritis," said Van Eldik.

"However, less is known about the potential importance of p38á MAPK in controlling inflammatory responses in the brain. Our work supports p38á MAPK as a promising clinical target for the treatment of CNS disorders associated with uncontrolled brain inflammation, including trauma, and potentially others like Alzheimer's disease. We are excited by our findings, and are actively working to develop drugs targeting p38a MAPK designed specifically for diseases of the brain."

Lead author of the paper Adam D. Bachstetter said, "I was surprised when I looked under the microscope at the brain tissue of mice that had a diffuse brain injury. Microglia normally look like a small spider, but after suffering a brain injury the microglia become like angry spiders from a horror movie. In brain-injured mice that lack p38a MAPK there were no angry-looking microglia, only the normal small spider-like cells. When I started the study I never expected the results to be so clear and striking. I believe that the p38a MAPK is a promising clinical target for the treatment of CNS disorders with dysregulated inflammatory responses, but we are still a long way from development of CNS-active p38 inhibitor drugs. "

The paper, " The p38a MAPK regulates microglial responsiveness to diffuse traumatic brain injury", is from a team of researchers including Linda Van Eldik, as well as Adam Bachstetter, Machi Kaneko and Danielle Goulding of SBCoA; and Rachel K. Rowe and Jonathan Lifshitz, director of the Translational Neurotrauma Research Program Barrow Neurological Institute at Phoenix Children's Hospital in Arizona.

Im Focus: Researchers Discover New Anti-Cancer Protein

An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.

The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...

Im Focus: Researchers at Fraunhofer monitor re-entry of Chinese space station Tiangong-1

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.

Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

Im Focus: Tiny implants for cells are functional in vivo

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.

In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
