The study, “Paeoniflorin Ameliorates Experimental Autoimmune Encephalomyelitis via Inhibition of Dendritic Cell Function and Th17 Cell Differentiation”, appeared in the journal…

Small natural variations within the DNA sequence of the gene for interleukin-16 (IL-16) were linked to an increased susceptibility to multiple sclerosis (MS) in a small group of Iranian patients. The study, “The Association of Interleukin-16 Gene Polymorphisms with IL-16 Serum Levels and Risk of Multiple Sclerosis,” was published in…

A genome-wide study has identified DNA regions associated with higher levels of circulating cytokines, small proteins that pay a role in inflammatory diseases such as multiple sclerosis (MS). Alterations in the levels and interplay of cytokines and growth factors play a key role in several inflammatory diseases, including MS. Cytokines help regulate…

An extension trial assessing generic glatiramer acetate (GTR) treatment in multiple sclerosis (MS) patients found that the formulation is as safe and effective as Copaxone (branded glatiramer acetate), and that switching to GTR is well-tolerated. The findings were in the study, “Switching from branded to generic glatiramer acetate:…

The immune system B-cells responsible for producing antibodies are different in those who develop multiple sclerosis (MS) as children, than in those who develop it as adults, a study shows. The research, “B-cell populations discriminate between pediatric- and adult-onset multiple sclerosis,” was published in the journal Neurology: Neuroimmunology & NeuroInflammation. Because only 3…

Cyclophosphamide (CPM) may delay the progression of disability in the first years of secondary progressive multiple sclerosis (SPMS), but patients must take it for two years — and many are unlikely to tolerate it for that long. The study, “Double-Blind Controlled Randomized Trial of Cyclophosphamide versus Methylprednisolone in Secondary Progressive…

Researchers have found a microbial protein from the Haemophilus influenza pathogen that is recognized by antibodies in a subpopulation of multiple sclerosis (MS) patients. The finding supports the idea of a link between microbial infections and neurodegenerative diseases like MS, whose causes are uncertain. Haemophilus influenza is an opportunistic pathogen…

Scientists unraveled the 3-D structure of a key receptor linked to inflammation in multiple sclerosis (MS) — the CC chemokine receptor 2 (CCR2) receptor — when it is bound to two inhibitor molecules simultaneously. This potentially important finding, which allows scientists to see how these molecules fit together, could aid in developing better therapeutics that…

The less oxygen that a mouse with multiple sclerosis (MS) has in the gray matter of its brain, the more mental and physical deterioration it is likely to have, a new study suggests. The study confirms previous research indicating a connection between low oxygen levels in a mouse’s gray matter and the development…

Data from the CARE-MS II clinical trial showed that Lemtrada (alemtuzumab) can lessen pre-existing disabilities in patients with relapsing-remitting multiple sclerosis (RRMS) who failed to respond adequately to previous disease-modifying therapies, according to a study of the trial’s data. The treatment was evaluated against Rebif (interferon beta-1a) therapy. The study, “Alemtuzumab…
