Effect of sun exposure on EBNA-1 antibody levels and risk of multiple sclerosis: a Swedish study

Takeaway

  • There is a synergistic effect between low sun exposure and high Epstein-Barr nuclear antigen 1 (EBNA-1) antibody levels and increased risk of multiple sclerosis (MS).

Why this matters

    Genetic and environmental factors influence susceptibility to MS. Results from this study provide evidence that will aid clinicians in counselling patients concerning potential MS preventative measures related to vitamin D and sun exposure.
