Why Is MS a More Frequent Complication of EBV Infection in Females?

Immunological Reviews, Volume 339, Issue 1, May 2026.
ABSTRACT Multiple sclerosis (MS) is a T helper (Th) cell‐mediated disease that targets central nervous system (CNS) white matter. This disease affects three times more females than males. For many years, the etiology of MS was not well understood and the exact nature of the autoimmune reaction was speculative.
