I get my medications the old-fashioned way. When I need to fill a prescription, I either go to the drug store or use a mail-order pharmacy — and usually, I have a copay. Sometimes the copay is just a few dollars, but sometimes it can be a few hundred.
Non-psychoactive cannabidiol (CBD), one of the active compounds in medical cannabis, significantly reduced clinical signs of multiple sclerosis (MS)-like disease in an experimental autoimmune encephalomyelitis mouse model. Researchers found that CBD promoted the increase of inflammatory-suppressor cells called myeloid-derived suppressor cells. The findings were reported in the study “Cannabidiol Attenuates Experimental Autoimmune…

Smoking increases the relapse rate in patients with relapsing-remitting multiple sclerosis being treated with Tysabri , an observational study suggests. Multiple sclerosis is a multifactorial disease associated with both genetic and environmental risk factors. Smoking, in particular, has been linked to numerous aspects of MS, including its development and progression. In a previous study, the research team looked at how smoking influences the relapse rate in RRMS patients being treated with interferon beta. From more than 800 patients, they found that smoking one pack per day (about 20 cigarettes) essentially interfered with the positive effect of the IFN-beta treatment and increased the relapse rate by 27%. The researchers then questioned whether the same was true for other treatments. Tysabri, developed by Biogen, is a monoclonal antibody that targets the alpha-4 integrin protein. By interfering with this molecule, the therapy prevents white blood cells from moving into the central nervous system, suppressing the immune reaction that contributes to MS symptoms. In the study, 355 Tysabri-treated RRMS patients from the Danish Multiple Sclerosis Centre were assessed. To gather information on smoking habits and body mass index, the patients filled out a 100-question survey. Data was collected between the start of the treatment and a two-year follow-up visit. Results showed that smoking one pack of cigarettes per day increases the relapse rate by 38% in RRMS patients on Tysabri. This increase in relapse rate takes into account both sex and age at the start of treatment, since age can affect the relapse rate. For example, an increase in age by one year raises the number of relapses by 2%. The researchers also looked at the relationship between smoking and the presence of two immune-related alleles: HLA-DRB1*15:01 and HLA-A*02:01. Previous studies showed that HLADRB1*15:01 is associated with an increased risk of developing MS, while HLA-A*02:01 is linked to a decreased risk. Although previous studies reported a link between smoking and these two alleles in MS patients, the current study did not find an association between smoking and carrying either of these alleles. Based on the results, the researchers concluded that smoking significantly increases the relapse rate in RRMS patients receiving Tysabri. According to the team, the results "add important information that hopefully will sharpen the focus on the overall harmful effects of smoking in MS patients."

Researchers Succeed at Generating Oligodendrocytes, Key to Myelin Renewal, in Tissue Created in Lab
Researchers at Case Western Reserve University School of Medicine have developed a cutting-edge laboratory technique able to turn human stem cells – special cells able to grow into any type of cell in the body – into brain-like tissues in a culture dish. They intend to use their tool to study how myelination – the deposition of myelin around nerve cells – occurs in the central nervous system, and how diseases such as multiple sclerosis (MS) impair this process. The experimental protocol to grow these structures outside an organis) is described in the study, "Induction of myelinating oligodendrocytes in human cortical spheroids," published in the journal Nature Methods. These structures, called “oligocortical spheroids,” are small spheres that contain all the major cell types usually found in the human brain, including oligodendrocytes — cells that produce myelin, which is the fatty substance that insulates nerve fibers. Previous cerebral organoid techniques failed to include oligodendrocytes. “We have taken the organoid system and added the third major cell type in the central nervous system — oligodendrocytes — and now have a more accurate representation of cellular interactions that occur during human brain development,” Paul Tesar, PhD, associate professor of genetics and genome sciences at Case Western's medical school and the study's senior author, said in a press release. Oligodendrocytes are essential to good brain health. Without these cells, myelin production is hampered and nerve cells cannot communicate effectively, and eventually they start to deteriorate. This is the starting point for many neurological disorders caused by myelin defects, including MS and rare pediatric genetic disorders like Gaucher disease. Using this new organoid system and these myelin-producing cells, researchers intend to study the process of myelination — how it occurs in normal circumstances and how neurodegenerative diseases disrupt this process. “This is a powerful platform to understand human development and neurological disease,” Tesar said. “Using stem cell technology we can generate nearly unlimited quantities of human brain-like tissue in the lab. Our method creates a ‘mini-cortex,’ containing neurons, astrocytes, and now oligodendrocytes producing myelin. This is a major step toward unlocking stages of human brain development that previously were inaccessible.” Researchers not only demonstrated that they were capable of generating mature oligodendrocytes derived from human stem cells in vitro, but they also showed these cells were able to exert their function and produce myelin starting at week 20 in a culture dish. Their improved organoid system could also be used to test the effectiveness of potential myelin-enhancing treatments. “These organoids provide a way to predict the safety and efficacy of new myelin therapeutics on human brain-like tissue in the laboratory prior to clinical testing in humans,” said Mayur Madhavan, PhD, co-first author on the study. To prove this point, researchers treated organoids with promyelinating compounds known to enhance myelin production in mice, and measured the rate and extent of oligodendrocyte generation and myelination. Under normal conditions, adding promyelinating drugs to cultured organoids increased the rate and extent of oligodendrocyte generation and myelin production, the team reported. But results differed in important ways using diseased organoids. Specifically, treating organoids generated from patients with Pelizaeus-Merzbacher disease — a fatal genetic myelin disorder — brought an in vitro recapitulation of the patients' symptoms. “Pelizaeus-Merzbacher disease has been a complicated disorder to study due to the many different mutations that can cause it and the inaccessibility of patient brain tissue,” said Zachary Nevin, PhD, co-first author on the study. “But these new organoids allow us to directly study brain-like tissue from many patients simultaneously and test potential therapies.” Altogether, these findings demonstrate that oligocortical spheroids could be a versatile in vitro system to study how myelination occurs in the central nervous system, and a possible model for testing new therapies for neurodegenerative disorders. “Our method enables generation of human brain tissue in the laboratory from any patient,” Tesar said. “More broadly, it can accurately recapitulate how the human nervous system is built and identify what goes wrong in certain neurological conditions.”
