Cell-mediated immunity to measles virus in multiple sclerosis: correlation with disability
Neurology
|February 1, 1978
Summary
Cell-mediated immune responses in early multiple sclerosis (MS) patients showed no significant difference to common viruses. However, a deficient viral response correlated with MS disability, suggesting it's a consequence, not a cause.
Area of Science:
- Immunology
- Neuroscience
- Virology
Background:
- Multiple sclerosis (MS) is a chronic neurological disease.
- Cell-mediated immunity plays a role in viral pathogenesis.
- The role of viral infections in MS etiology is debated.
Purpose of the Study:
- To investigate cell-mediated immune responses to viruses in early MS patients.
- To determine if viral infections are a cause or consequence of MS.
Main Methods:
- Lymphocyte blastogenic transformation assay used to measure immune response.
- Tested reactivity against measles, parainfluenza, and vaccinia viruses.
- Compared responses in 12 early MS patients and healthy controls.
Main Results:
- No significant difference in lymphocyte reactivity to tested viruses between MS patients and controls.
- Significant inverse correlation found between viral response and MS disability.
- Deficient response to measles and vaccinia viruses linked to higher disability.
Conclusions:
- A deficient cellular immune response to common viruses is likely a consequence of MS, not a causal factor.
- Viral infections may not initiate MS but could influence disease progression.
- Further research needed to understand the complex interplay between viruses and MS.
