BU Researchers ID Possible Biomarker for Diagnosing CTE during Life

Possible Biomarker for Diagnosing CTE during Life | BU Today | Boston University

Chronic traumatic encephalopathy (CTE), a progressive degenerative brain disease found in people with a history of repeated head trauma, can currently be detected only after death, through an autopsy. Absent being able to diagnose the disease in living patients, researchers cannot develop treatments for CTE.

In the past several years, scientists have taken small steps forward in identifying possible biomarkers for the disease, and now researchers from the Boston University School of Medicine and the VA Boston Healthcare System (VABHS) have discovered a new biomarker that may potentially allow the disease to be diagnosed in the living.

In a study published Tuesday in the journal PLOS ONE, the researchers found that the biomarker, the protein CCL11, might also help distinguish CTE from Alzheimer’s disease, which often presents with symptoms similar to CTE and also can be definitively diagnosed only postmortem. The ability to diagnose CTE in the living would allow not only for the development of possible therapies to treat the disease, but also for research into prevention.

“This is a step forward from our knowledge gained in understanding CTE from brain donations,” says study senior author Ann McKee, a MED professor of neurology and pathology, director of BU’s CTE Center, and chief of neuropathology at VABHS. “It’s a hopeful step. The whole point is to understand as much as we can from the individuals who’ve fallen, so we can apply it to our future veterans and athletes.”

The new research “offers a possible mechanism for distinguishing between CTE and other diseases,” says study first author Jonathan Cherry, a MED postdoctoral fellow in neurology. “By making it possible to distinguish between normal individuals and individuals with Alzheimer’s disease, CTE therapies can become more targeted and hopefully more effective.”

Cherry and the other researchers studied the brains of 23 former college and professional football players. They compared them to the brains of 50 nonathletes with Alzheimer’s disease and 18 nonathlete controls.

They found baseline levels of CCL11 in the brains of the nonathlete controls and the nonathletes with Alzheimer’s disease, but the CCL11 levels were significantly elevated in the brains of people with CTE. They then compared the degree of elevation of CCL11 to the number of years those people played football and found that there was a positive correlation between the CCL11 levels and the number of years played.

The researchers were able to take postmortem samples of the cerebrospinal fluid (CSF) from four of the control individuals, seven of the people with CTE, and four of the people with Alzheimer’s. They found that CCL11 levels in the CSF were similarly normal in the control individuals and people with Alzheimer’s, but elevated in those people with CTE. Cherry says that this suggests that the presence of CCL11 might one day be able to assist in the detection of CTE in the living.

Additional studies are needed, the study authors say, to determine whether increased levels of CCL11 occur early or late in the CTE disease process, and whether CCL11 levels might be able to predict the severity of a person’s disease.

“What’s most likely going to happen is that we’ll end up with a panel of biomarkers—maybe three or four—that will let us diagnose CTE reliably,” Cherry says.

With the fake ass worry shown by the NFL brass this weekend, it's good to know some actual good might come about soon. We need to start saving lives.

If this is proven to be reliable it could save lives and football as we know it...

 

[Leasy]

Let the cac sport die.

Actually it would end football

Once it's proven that high schoolers are suffering from cte it's a wrap

High schoolers are getting concussed... it's a given that some have cte. If this is a true identifier we can at least work on developing treatments. We'd be better informed on necessary rest between games and practices. Adjustments to equipment and rules could be tested using this information for a better assessment of how effective they are in minimizing cte. I think this is good for football and I'm certain NFL has been pouring money into this research to save the game...

The NFL would pay to bury this research

Necessary rest? Like a game every month?


If this research is legit only psychos would continue to play football and there won't be enough of them

So you think cte only effects football players? Now that the cat is out of the bag the NFL wants no advancement in the diagnosis and potential treatment? Or they want the mystery to hover the conscious of soccer moms like the boogeyman? Ok...

That's sh!t they've been doing the past 25 years

They don't want it researched, they want it to disappear while the money keeps rolling in

They have been trying to improve the safety and they will continue to do so. Identifying this protein will help in testing how significant certain improvements are. Wanting this to disappear is not an option and irresponsible thinking. To prevent lawsuits they have to at least appear like they are trying to be better informed. Not the opposite...
