Abstract:
Interplay between susceptibility genes and environmental factors is considered important player in the genesis of multiple sclerosis (MS). Among environmental factors, a role for an infectious pathogen has long been considered central to the disease process. This opinion has support both from epidemiological data and the findings of immunological abnormalities in spinal fluid that reflect an immune response to an as yet undetermined antigen, possibly a pathogen, in the cerebrospinal fluid. Our review will outline the current understanding of the role of infection in the causation and progression of MS. We will review the data that point to an infectious cause of MS and consider the specific agents Chlamydophila (Chlamydia) pneumoniae, Human Herpes Virus 6, and Epstein-Barr Virus, that are implicated in either the development or progression of MS.
Insights
Infectious agents may play a key role in causing and worsening multiple sclerosis (MS). This review examines evidence linking pathogens like Chlamydophila pneumoniae, Human Herpes Virus 6, and Epstein-Barr Virus to MS development and progression.
Area of Science:
- Neuroimmunology
- Infectious Diseases
- Genetics
Background:
- Multiple sclerosis (MS) genesis involves interplay between genetic susceptibility and environmental factors.
- Infectious pathogens are a long-suspected central factor in MS pathogenesis.
- Epidemiological data and immunological findings in cerebrospinal fluid support an infectious etiology for MS.
Purpose of the Study:
- To review the current understanding of infection's role in MS causation and progression.
- To examine evidence supporting an infectious cause for MS.
- To discuss specific implicated infectious agents.
Main Methods:
- Literature review of epidemiological studies.
- Analysis of immunological data from cerebrospinal fluid.
- Examination of research on specific pathogens implicated in MS.
Main Results:
- Evidence suggests a significant role for infectious agents in MS.
- Specific pathogens, including Chlamydophila pneumoniae, Human Herpes Virus 6, and Epstein-Barr Virus, are implicated.
- These agents may contribute to both the development and progression of MS.
Conclusions:
- Infection is a critical environmental factor to consider in MS.
- Further research into specific pathogens is warranted to understand their role in MS.
- Understanding the interplay of infection and genetics is key to MS management.

Infection
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
