Chronic stress and inflammation in the brain can cause multi-organ dysfunction including severe gut failure, mediated by a newly identified nerve pathway in animal models of multiple sclerosis, a Japanese study shows. MS is an autoimmune disease caused by CD4+ T-cells that cross the blood-brain barrier protecting the central nervous system. This inflames and stresses the brain and spinal cord. In previous studies, a team led by professor Masaaki Murakami of Japan's Hokkaido University showed that these cells could cross the blood-brain barrier in specific sites. These entrance sites depend on brain regional activation, which was found to be triggered by specific nerve interactions — a mechanism the team called gateway reflexes. In collaboration with other Japanese researchers and a team from Germany, the project aimed to address the potential correlation among chronic stress, brain inflammation and organ failures in MS. Using mice with MS-like disease — the experimental autoimmune encephalomyelitis model — researchers found that animals that had autoreactive CD4+ T-cells and which were exposed to stressful conditions developed severe symptoms such as gastrointestinal failure, or even death. Detailed analysis of the animals' brains showed that in stressed mice, CD4+ T-cells accumulated in two specific sites in the center of the brain around blood vessels. This event would cause inflammation around those vessels, and activation of a nerve pathway that is commonly turned off. This switch led to gut dysfunction, bleeding and failure. "These results demonstrate a direct link between brain micro-inflammation and fatal gastrointestinal diseases via the establishment of a new neural pathway under stress," Murakami, the study's senior author, said in a news release. Researchers were able to prevent gut symptoms by inhibiting inflammation in the brain or blocking the nerve pathway responsible for driving the signals from the brain to the gastrointestinal tract. "Micro-inflammation in the brain is also seen in Alzheimer's disease and Parkinson's disease," Murakamai concluded. "So it's of particular interest to investigate possible connections between brain micro-inflammations and organ dysfunctions, including those within the brain itself, in those patients."

It’s been an incredibly bad few weeks, so I’m not surprised that I spent recent days wondering if I had incurable liver disease. Living with chronic illness, plus the internet, plus now justifiable hypochondria, is a very dark nexus. It started with a UTI that has been persistent for nigh…

MSBase and icometrix have joined efforts in a large-scale project to identify imaging markers of multiple sclerosis (MS) that could help diagnose the disease in its early stages. The combination of magnetic resonance imaging (MRI) information collected from MS patients with clinical information from the MSBase Registry can offer new insights in disease progression, potentially leading to new predictive tools for MS. It may also promote more standardized use of imaging measures in clinical practice. With more than 52,000 MS patients, the MSBase Registry is an international database committed to collecting patients’ information as well as sharing, tracking and evaluating overall outcome data in MS and other neurological conditions. Until now, the MSBase Registry included only descriptive information regarding patients' imaging analysis results, with no access to full imaging data. This joint, large-scale project will include MRI scan data routinely acquired in clinical setting taking advantage of icometrix’s software platform, MSmetrix. “We wish to unlock the power of MRI for personalized monitoring in MS," Helmut Butzkueven, director of MSBase, said in a press release. "The MSBase Scientific Leadership group has selected MRI integration as the top strategic priority for MSBase. We believe that already conducted MRI scans represent an enormous missed opportunity, because advanced measurements to assess change over time from these scans are not currently in practical use.” Butzkueven said MSBase "will test the predictive power of this unlocking of MRI data in the first phase," with a total of 10,000 MRI data points in at least 3,000 MS patients from all over the world. The project is expected to identify disease progression markers that could help detect early signs of MS by MRI evaluation. This investigator-initiated collaboration between icometrix and the MSBase Foundation is being supported by three global pharmaceutical giants: Novartis, Biogen and Roche. “MRI measures play an essential part in the complex puzzle of MS,” said Danny Bar Zohar, global head of neuroscience development at Novartis. “Partnering with MS Base and icometrix in this exciting project will bring the acquisition of high-quality real world data to the next level, ultimately improving the outcome of people living with MS.”

MS brain inflammation is a result of interactions between processes in the brain and the rest of the body, with interferon-gamma (IFN-gamma) being a key player, according to a detailed analysis of cytokines in the spinal fluid and serum of MS patients. Russia’s Kazan Federal University found that IFN-gamma activates other…

A significant percentage of multiple sclerosis (MS) patients struggle with improper diagnoses and ineffective treatments, a national survey of more than 5,300 patients found. The fifth annual survey, “MS in America 2017,” was conducted by Health Union between Jan. 25 and March 1, 2017. It was released through the…
