Summary
This paper reviews melatonin's immunomodulatory roles, arguing it functions as an 'immune buffer' that stimulates immunity under basal conditions while acting as an anti-inflammatory agent during exacerbated responses. For lighting designers and healthcare practitioners, this suggests that light-driven melatonin suppression may have complex downstream immune consequences beyond simple sleep disruption.
Key Findings
- Melatonin is proposed to act as an immune buffer: immunostimulant under basal or immunosuppressive conditions, and anti-inflammatory under acute inflammation
- Review covers multiple immune contexts including infection, autoimmunity, vaccination, and immunosenescence, suggesting broad clinical relevance of melatonin modulation
- No specific quantitative effect sizes or p-values are reported; conclusions are qualitative synthesis of existing literature
