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.
