Highlights •Melatonin levels negatively correlate with multiple sclerosis relapses in humans •Melatonin treatment ameliorates pathology in a mouse model of multiple sclerosis •Melatonin blocks ROR-γt expression and Th17 differentiation •Melatonin boosts Tr1 development via Erk1/2 and ROR-α
Researchers have found an explanation that could lead to a deeper understanding of multiple sclerosis and more targeted treatment options for patients. By first looking broadly at possible environmental factors and then deeply at preclinical models of MS, the research team found that melatonin – a hormone involved in regulating a person’s sleep-wake cycle – may influence MS disease activity.
Why do symptoms of multiple sclerosis (MS) seem to get better in the winter and worse in the summer? The...
