Abstract:

Multiple sclerosis (MS) is an inflammatory neurological disease that is widely regarded as the outcome of complex interactions between a genetic predisposition and an environmental trigger. Epstein-Barr virus (EBV) has recently been associated with the onset of MS, yet understanding how it elicits autoimmunity remains elusive. Neuroinflammation, including the entry of autoreactive T cells, likely follows a breach of the blood-brain barrier (BBB) leading to CNS lesions in MS. We show that EBV can infect human BBB cells leading to increased production of pro-inflammatory mediators that result in immune cell adherence thus modeling a key step in MS pathogenesis.
