Implications of dietary salt intake for multiple sclerosis pathogenesis

In recent years it has become increasingly clear that, alongside genetic risk factors, environmental factors strongly influence the incidence and severity of multiple sclerosis (MS). Based on observations from epidemiological studies, the potential contribution of dietary habits has lately been a matter of debate. Recently it was shown that high salt conditions promote pathogenic T-cell responses and aggravate autoimmunity in an animal model of MS, suggesting that high dietary salt intake might promote central nervous system (CNS) autoimmunity. However, so far, not much is known about the influence of dietary salt intake on MS disease pathology. Here, we discuss the association of dietary salt levels and MS with a special focus on the mechanisms of salt-mediated modulation of the different cell types critically involved in the pathophysiology of MS. via Multiple Sclerosis Journal.
