*note: video describes how multiple sclerosis is currently diagnosed. Wednesday's published paper is going to change all this.
Last year’s research done by Gladstone Institute Investigator Katerina Akassaglou, Ph.D. and her team had revealed an important start in the beginning stages of multiple sclerosis (MS) and Wednesday’s paper shows what they did with those discoveries.
They were able to show, last year, that MS begins with the break down of the blood brain barrier (BBB); it physically separates from blood circulation thereby allowing fibrogen to seep into the brain.
The protein thrombin then coverts fibrogen into fibren, a fibrous substance, formed in the coagulation of the blood, and, since fibren aren’t suppose to be in the brain; it triggers the body’s immune response.
The researchers continued to build upon this discovery and were able to develop “a fluorescently labeled probe specifically designed to track thrombin” and discovered not only it being active in the beginning stages of the disease but that it also interconnected with the severity of MS.
To understand how important a find this is, one needs to try to comprehend that MS sufferers, each and every single one, didn’t even know they had the disease until damage had already been done.

Dr. Akassaglou stated, “We already knew that the buildup of fibrin appears early in the development of MS—both in animal models and in human patients, so we wondered whether thrombin activity could in turn serve as an early marker of disease. In fact, we were able to detect thrombin activity even in our animal models even before they exhibited any of the disease’s neurological signs.”
“…even before they exhibited any of the disease’s neurological signs.” The feeling of awe in that statement cannot be overstated.
Using a type of molecular probe that delivers florescent agents to a particular area of the body, an Activatable Cell-Penetrating Peptide (ACPP), they analyzed the stages thrombin showed itself and “specific disease ‘hot-spots,’ regions where neuronal damage developed over time,” said Gladstone Staff Research Scientist Dimitrios Davalos, Ph.D.
Like a one-two punch, these scientists not only proved thrombin-specific probes can be used in early disease detection, they are also able to show thrombin activity is directly tied to the ruin of the myelin sheath.
They essentially were able to take people to the beginning of MS - when it takes its baby steps into our brains.
