Multiple sclerosis etiology--an Epstein-Barr virus hypothesis
1New York State Office of Mental Retardation and Developmental Disabilities, Institute for Basic Research in Developmental Disabilities, Staten Island 10314.
Abstract:
The opinion has been expressed frequently in the literature that MS is caused by a combination of an environmental agent and genetic factors, possibly with an autoimmune component. However, the specific environmental agent has not as yet been identified. This paper describes cumulative circumstantial evidence which strongly points to a post-pubertal primary Epstein-Barr virus infection as this unidentified etiological event in the induction of MS disease.
Insights
A primary Epstein-Barr virus infection after puberty may trigger multiple sclerosis (MS) in genetically susceptible individuals. This research presents evidence linking this viral event to the onset of MS disease.
Area of Science:
- Neurology
- Virology
- Immunology
Background:
- Multiple sclerosis (MS) is a chronic neurological disease with suspected genetic and environmental causes.
- The specific environmental trigger for MS remains unidentified in scientific literature.
- An autoimmune component is also frequently suggested in the etiology of MS.
Purpose of the Study:
- To identify the specific environmental agent responsible for inducing multiple sclerosis (MS).
- To present evidence supporting a particular viral infection as the etiological event in MS.
Main Methods:
- Review and synthesis of cumulative circumstantial evidence.
- Analysis of the temporal relationship between Epstein-Barr virus infection and MS onset.
Main Results:
- The evidence strongly implicates a primary Epstein-Barr virus (EBV) infection.
- This infection appears to be a critical etiological event occurring post-puberty.
- The findings suggest EBV as the long-sought environmental factor in MS induction.
Conclusions:
- A post-pubertal primary Epstein-Barr virus infection is a likely etiological factor in multiple sclerosis.
- This viral trigger, in conjunction with genetic predisposition, may initiate the disease process.
- Further research into EBV's role could lead to new MS prevention and treatment strategies.
