Gladstone scientists will investigate their blood detective; Destroying memory storage sites in the brain and new medicines may be realized

SAN FRANCISCO – 5 February, 2019 – (

Alzheimer's disease has a long-standing patient's patient in the large blood vessels in the brain. Some of these changes can also contribute to an interesting decline related to age in people without dementia. However, the ways in which such vascular antibiotics contribute to insightful feelings are largely a mystery. So far, that is.

Scientists at the Gladstone Institutes, led by Superintendent Katerina Akassoglou, Ph.D., showed the first time that blood-spreading protein called fibrinogen is responsible for a series of events molecular cells and cells; Destroying links between neurons in the brain and due to mental decline.

Akassoglou and her team have used image image technology to investigate mouse brains and human brains from patients with Alzheimer's disease. They also made the first three-dimensional measurement images that show that blood-brain obstacles can be; Alzheimer's disease reduction.

In their study, published in the scientific magazine Neuronthe researchers found that fibrinogen, after being fired from the blood into the brain, Implement cellular cellular cells and remove them to destroy important links between neurons. These connections, called synapses, are essential for neurons to interact with each other.

Previous studies have shown that the abolition of synapses causes memory loss, common sex in Alzheimer's disease and other dementia. Indeed, scientists have shown that the prevention of fibrinogen from the operation of the brain protection cells of immune mice models of Alzheimer's disease has been lost.

"We found that blood can reduce brain in the abolition of neuronal connections that are important for memory work," explains Akassoglou, who is also a neurologist professor at UC San Francisco (UCSF). "This may change how we reflect on the cause and cure that may be of an emotional downturn in Alzheimer's disease and other disease diseases."

The team showed that fibrinogen could be present even in brains that do not have amyloid records, which are the focus of different medical strategies that suffer in large clinical tests. The researchers showed that so much fiberogen in a healthy brain included the same immune cell activity activity and the loss of synapses that they saw in Alzheimer's disease.

"Traditionally, the amyloid in the brain plates in the brain are remembered as a reminder of memory loss and anxiety in Alzheimer's disease," says Mario Merlini, the first author of Inspector and research researcher at the Akassoglou laboratory in Gladstone. "Our work identifies another buyer who can be accountable for synapses."

Scientist data will help the result of recent human studies in which older people with fascinating mental disorders showed similar levels of interesting decline such as those that were appropriate for age with amyloid geography. However, patients with the two types of mental illness were getting worse and faster. Other surveys also indicated a fascinating mental disorder as a strong predictor of an interesting decline that can work independently from amyloid geophysics.

"With the human data that shows that early changes are early and addicted to amyloid, a decision from these checks may have to be targeted by individual remedies if we to ensure that maximum protection against the destruction of neuronal connections that persists in the recession, "said Akassoglou.

Interestingly, Akassoglou and his recent antibody colleagues have improved the interaction between fibrinogen and molecle on brain protection cells. In a previous study, they showed these mice modules that were protected by an antibody of Alzheimer's disease from brain tumor and neuronal damage.

"These incredible conclusions are very important in developing our understanding of what includes brain roots and brain pressure to Alzheimer's disease progress," said Lennart Mucke, MD, co- author of the study and director of the Gladstone Institute of Disease Nation. "The evaluations that our survey may also be able to work in a range of other diseases that link slabs in blood-brain barring with a brain failure , which includes multiple sclerosis, bad injuries, and traumatic encephalopathy. It has wide-ranging effects. "
