Specific antibodies identified that may explain part of the link between multiple sclerosis and the Epstein-Barr virus

Epstein-Barr virus infection appears to be a necessary condition for developing multiple sclerosis, but the specific mechanisms that cause it in some people are not known. An international study of more than 1,300 people, including 650 patients, has found that elevated production of certain antibodies increases the risk of developing the disease. These antibodies target a specific protein in the virus, but can in turn act in a cross-species manner and damage other similar proteins in the nervous system. The results are published in the journal PNAS.

Specific species of microbiota associated with severity of multiple sclerosis

A team from the University of Iowa (USA) has found a relationship between specific species of microbiota bacteria and the severity of multiple sclerosis. Specifically, a lower ratio between the quantities of Bifidobacterium and Akkermansia was related to the disease and to a worse course of the disease, both in mice and in two cohorts of patients and people without the disease. According to the authors, who publish the results in the journal PNAS, the finding could be used to improve the diagnosis and treatment of multiple sclerosis.

Reactions to study linking sleep deprivation in adolescence with increased risk of multiple sclerosis

A Swedish study has found an association between lack of sleep or poor quality sleep during adolescence and an increased risk of developing multiple sclerosis later in life. They put the relative increased risk at 40 %. The results are published in the Journal of Neurology, Neurosurgery and Psychiatry.
