Disease progression in multiple sclerosis (MS)–an inflammatory demyelinating and neurodegenerative disease with a presumed T-cell driven autoimmune origin–has long been hypothesized to be associated with stress. However, this notion has only recently been supported by prospective clinical studies. Several clinical and molecular studies in MS and its animal models have recently shown disruptions in the communication between the immune system and the two major stress response systems, the hypothalamo-pituitary-adrenal (HPA) axis and the autonomic nervous system. Insensitivity to glucocorticoid and beta-adrenergic modulation might be involved in overshooting inflammation in MS, whereas hyperactivity of the HPA axis has been linked to neurodegeneration and increased disability. Here, we integrate findings from molecular, cellular, experimental, clinical and epidemiological research to describe the involvement of stress response systems in MS pathogenesis and progression.Trends Immunol. 2005;26:644-52.
