A blood-clotting protein called fibrinogen prevents myelin production and blocks the neuron remyelination repair process in mice, a study finds. The study, “Fibrinogen Activates BMP Signaling in Oligodendrocyte Progenitor Cells and Inhibits Remyelination after Vascular Damage,” appeared in the journal Neuron. Its conclusions offer new insights and…

In the future, a blood test may make diagnosing multiple sclerosis (MS) much easier, thanks to newly identified biomarker patterns that distinguish between MS patients and healthy people. The test could also correctly detect primary progressive MS (PPMS) in patients who also had relapsing-remitting disease (RRMS). Australian researchers suggest that…

#MSParis2017 – Trial to See if Disease-modifying Therapies Not Necessary in Older MS Patients This tops my list this week because, at age 69, I certainly fit the definition of an “older” MS patient. The study is hoping to enroll 300 MS patients in the U.S. who…

The generation of a thin myelin sheath during remyelination — one that continues to protect nerve cells over time — is indicative of the long-term health and activity of the central nervous system (CNS) in demyelinating diseases such as multiple sclerosis (MS), a new study shows. These findings, which aim…

Researchers, using two different kinds of stem cells in rats, were able to regenerate oligodendrocytes — myelin-producing brain cells that are defective in multiple sclerosis (MS). They were also able to grow adult neural stem cells in laboratory cultures and prod them to develop into oligodendrocytes. The exact cause of MS is unknown — including what triggers attacks on myelin — but the loss of oligodendrocytes seen in the disease is known to play a role in its progression. Nerve cells in the brain send their signals through their axons, long arm-like structures that extend out from the centers of the nerve cells. The signals are electrical pulses transmitted along the length of an axon. Oligodendrocytes provide the insulation — called myelin — that wraps around axons, speeding up the transmission of electrical signals through the nerve cells. Loss or malfunction of oligodendrocytes means that signaling in the brain is impaired. It is this slowing of signaling that is thought to cause MS symptoms. Researchers from the Heinrich-Heine-University, Germany, with support from British and Chilean colleagues, designed a novel approach to regenerate oligodendrocytes, according to a press release. Stem cells are immature cells that give rise to differentiated cells — cells with a specific function, such as oligodendrocytes. Adult neural stem cells can divide and produce nerve cells and other brain cells, including oligodendrocytes. However, in normal circumstances, the regeneration of cells that take place in the human brain is not enough to repair the damage seen in MS. The researchers set out to find conditions that would promote the differentiation of adult human NSCs into oligodendrocytes. They discovered that another type of stem cell, mesenchymal stem cells (MSCs), could provide the signals required. First they tested their system in rats, and found that by using factors produced by human MSCs, they could induce the growth of new oligodendrocytes in the animals. Then they grew adult NSCs in the laboratory, and using the same factors from human MSCs were able to promote the establishment of oligodendrocytes in the cultured cells.

Aerobic exercise strengthens brain connections in people with relapsing-remitting multiple sclerosis, Jan-Patrick Stellmann, with University Medical Center Hamburg-Eppendorf in Germany, reported at the 7th Joint ECTRIMS-ACTRIMS Meeting in Paris that ran from Oct. 25–28. According to Stellmann, "aerobic exercises are considered to improve mobility, fatigue, depression and cognition in MS," and also to "promote neuroprotective or neuroregenerative mechanisms." For the study, the team used MRI to examine how exercise affected different types of brain connections. They recruited 57 RRMS patients and 30 healthy controls to the study. Women made up more than two-thirds of the patient group, which had a mean age of 39. Patients only had mild disability, with a mean score of 1.5 on the Expanded Disability Status Scale. Researchers randomly assigned about half the group to a supervised and individually adapted aerobic exercise program, consisting of 22 sessions of up to one hour each. Others were assigned to a waiting list — with the intent of taking up exercise after three months — and served as a control group. MRI scans at the study's beginning revealed that patients had more so-called functional connections, but fewer structural ones, than healthy controls. It is known from earlier studies that most RRMS patients show abnormalities in functional connections, but some researchers find increases while others decreases in these connections. Functional and structural connections appear on different types of MRI scans — ones that make use either of blood flow changes or of the properties of water molecules in the white matter of the brain. The deviations were particularly pronounced in highly connected hub regions, the researchers said. After three months, functional connections increased across the entire brain among exercising patients, but decreased in those on the waiting list. Structural connections also increased among patients who exercised, while no change was detected among control patients. Researchers also noted that exercising patients grew more local connections, mostly in hub regions, compared to those who did not exercise. While it is generally accepted that aerobic exercise promotes neuroprotective and regenerative processes within the brain, the study demonstrated that exercise, in only three months, did indeed affect how the brain is wired. "Short-term aerobic exercise increases functional and structural connectivity," Stellmann concluded. "Already after three months, exercise lead to functional and structural reorganization of brain networks." The researcher highlighted the difficulties in obtaining financial support for trials on exercise. And he emphasized that patients should be encouraged by their doctors to exercise regularly.

Inhibiting a protein found at high levels in immune cells located in the brain can rejuvenate myelin, the protective coating around nerve cells, according to a multiple sclerosis study in mice. Blocking the protein, known as the colony-stimulating factor 1 receptor, or CSF1R, can also prevent the immune cells from…

Radiologically isolated syndrome (RIS) is a rare and relatively recent condition in which people have multiple sclerosis (MS)-like brain and spinal cord lesions without showing disease activity. But since the establishment of the RIS diagnosis, researchers have not reached an agreement on whether these patients should receive MS disease-modifying therapies.
