Last weekend a mother brought 4,000£ ($5,200 U.S.) of medicinal cannabis from Holland into the U.K. for her daughter with severe epilepsy. It was confiscated by customs. Last year medicinal cannabis was partially legalized in the U.K. when a similar incident happened. Doctors can now issue prescriptions.

A link between fat molecules called ceramides and worsening disease in overweight and obese people with multiple sclerosis appears to exist, a study reports, with its findings suggesting that ceramides prompt the growth of immune cells called monocytes, which in turn spurs disease progression. These results also strengthen the likelihood that lifestyle factors, like diet and weight, can act as disease modifiers, its researchers said. High body mass index has been linked to the risk of developing MS, but for reasons that aren't clear. One idea is that weight-induced differences in lipids (fat molecules) in the blood, because they are involved in several cellular signaling processes, may affect MS and its course in people with higher BMIs. To test this hypothesis, a team led by researchers at the Advanced Science Research Center (ASRC) at The Graduate Center and at the Icahn School of Medicine at Mount Sinai analyzed 54 patients with relapsing-remitting MS (MS), ages 18 to 60, and with normal or high BMIs (27 people in each group). Participants were followed for two years. BMI is a measure of body fat based on height and weight. A normal BMI is defined as one between 18.5 and 24.9, while a person is considered overweight with a BMI of 25–29.9, and obese it is 30 or higher. Researchers took blood samples, and looked for differences between the groups in terms of both immune cells and blood lipid profiles. They then validated their findings in a separate group of 91 RRMS patients. Patients with high BMIs tended to have more monocytes than those with normal BMIs. Monocytes can travel through the blood to tissues where they develop into macrophages, immune cells with various functions that are best known for "eating" invading bacteria. Monocytes can also travel to the brain and damage nerve fibers. Overweight and obese patients also had significantly higher levels of ceramides compared with normal-weight patients, and the researchers wondered if a link might exist between the two. Through a set of experiments in cells, they discovered that ceramides cause epigenetic changes in monocytes; that is, they alter the way their genomes are "read," so they alter gene activity. Specifically, ceramide-treated cells showed a type of epigenetic change called methylation — which generally turns genes "off" — in genes that normally help prevent cells from dividing. Conceptually, these genetic changes serve to unleash monocytes, leading them to grow more (proliferate) than they otherwise might. The researchers also found more methylation on the genomes of monocytes from high-BMI patients than those from low-BMI patients, and they noted that the overweight or obese patients also tended to have greater disease activity, worse disability progression, and more brain lesions on MRI (magnetic resonance imaging) scans on follow-up. Finally, the researchers tested a mouse model of MS, giving one group of mice a standard diet and another a high-fat diet. Mice fed the high-fat diet were found to have greater disease severity, more brain lesions, and more monocytes, confirming the findings seen in MS patients. "This study gives us a much-needed view into the environmental influences that can affect and change the behavior of cells in an individual's body," Kamilah Castro, the study's first author, said in a press release. "Our findings suggest that increased levels of saturated fat as a result of dietary habits are one likely cause of the epigenetic changes that advance MS, which gives us a starting point for a potential intervention." According to the team, the findings support the concept of nutri-epigenomics: that is, the ability of food to alter the way the genetic information is interpreted by each cell, and suggest that "weight management and dietary intervention" might affect MS prognosis. One limitation was the study's small size, its researchers noted. "While we consider our results … very exciting and mechanistic, we acknowledge that the potential consideration of ceramide levels as biomarkers for disease progression in MS would require validation ... using larger cohorts with a longitudinal and/or cross-sectional design," they concluded. "It will also be important to evaluate the effectiveness of dietary intervention (with an emphasis on the reduction of specific classes of saturated fats), as potential modulator of plasma ceramide levels and possibly of disease course in MS patients."

Two newly identified variants of the known pharmaceutical agent chloroindazole showed significant anti-inflammatory and neuroprotective benefits in a mouse model of multiple sclerosis, a new study shows. Multiple sclerosis is an autoimmune, demyelinating disease of the central nervous system with no known cause or cure. Patients with MS characteristically show loss of the myelin sheath, a protective coat in nerve cells that helps increase cell-to-cell signaling. Several studies have suggested that estrogens — a type of hormone — are beneficial to the functioning of the central nervous system, and help regulate the immune system. Thus, they are attractive candidates for the treatment of MS. However, despite their potential to treat MS, estrogen-based therapies can have several undesirable side effects, such as feminizing male recipients and increasing the risk of developing breast and endometrial cancers in females. Interestingly, estrogens work by binding and activating two different types of receptors: the estrogen receptor (ER)α and ERβ. The cancer-inducing effects of estrogens are mediated mainly through estrogen receptor ERα. Hence, therapies that specifically target ERβ can bypass these deleterious effects. Chloroindazole (IndCl), a pharmaceutical agent, has up to 100-fold relative binding affinity for ERβ over ERα. IndCl has been shown previously to have beneficial effects on modulating the immune system and the central nervous system, and inducing myelination of nerve cells in mouse models of MS. Furthermore, IndCl and other ERβ-activating agents directly support the growth, differentiation (maturation), and overall myelination activity of oligodendrocytes, which are the nerve cells that produce the myelin sheath. Therefore, in order to optimize the benefits of IndCl, researchers developed and screened seven novel IndCl analogues for their ability to promote oligodendrocyte survival, growth, and differentiation. These analogues have a molecular structure closely similar to that of IndCl, but interact with estrogen receptors in subtly different ways. Among these seven compounds, researchers found two analogues — IndCl-o-chloro and IndCl-o-methyl — that stimulated growth and differentiation similar to the original IndCl. Next, researchers evaluated the benefits of these compounds in a mouse model of MS — the experimental autoimmune encephalomyelitis (EAE) mouse model — to determine whether they could alter the disease course, white matter pathology (level of demyelination), and inflammation. Results indicated that both compounds “ameliorated disease severity, increased mature OLs [oligodendrocytes], and improved overall myelination in the corpus callosum and white matter tracts of the spinal cord,” researchers wrote. Corpus callosum is a thick band of nerves that connect the left and right side of the brain. White matter tracts connect the cortex (the largest part of the brain) with other areas in the central nervous system. These beneficial effects were accompanied by a reduced production of the toxic, inflammatory molecules interferon-γ and CXCL10. Additionally, IndCl-o-methyl also reduced the levels of peripheral interleukin (IL)-17, a molecule that strongly induces inflammation. Furthermore, IndCl and both analogues upregulated the expression of a compound called CXCL1, which is associated with increased production of oligodendrocytes. Not only were these two newly identified compounds equivalent to IndCl, but the two analogues performed better in reducing disability and encouraging remyelination than the original compound, and without any obvious side effects. “The o-Methyl and o-Chloro IndCl analogues represent a class of ERβ ligands that offer significant remyelination and neuroprotection, as well as modulation of the immune system; hence, they appear appropriate to consider further for therapeutic development in multiple sclerosis and other demyelinating diseases,” the researchers concluded. “We believe we created a drug that does two things really well, modulating inflammation and allowing axon remyelination. No other drug on the market can do these two things simultaneously,” Seema K. Tiwari-Woodruff, said in a press release written by Stacy Kish. Tiwari-Woodruff is the study's lead author. “The most amazing part of the study is that these new analogues of a known estrogen modulator, chloroindazole, are superior in treating mouse model of multiple sclerosis,” she added. The team has patented the analogues, and hopes to begin further pharmacological and toxicity studies soon.
