MS and HHV6

[Guest guest]

<sigh> when will science ever catch up?

I have articles making this connections from 5 yrs ago

AND read " THe Virus Within "

Multiple Sclerosis Linked to HHV-6A Virus

Evidence Presented at American Neurology Association Annual Meeting

Note: One of the theories of autism is that it is triggered by this

Primezone -- Dr. Claude Genain of the University of California San

Francisco Medical Center presented evidence at the American Neurology

Association Annual Meeting this week that shows a direct link between human

herpes virus 6 variant A (HHV-6A) and a multiple sclerosis-like illness.

Dr. Genain injected common marmoset monkeys with HHV-6 variants A &

B. Most notably, only infection with HHV-6 variant A resulted in illness.

The monkeys developed lab evidence and signs of chronic autoimmune

demyelination of the central nervous system, the hallmark of multiple

sclerosis. This is the first time that any animal infected with HHV-6A has

developed clinical pathology of the central nervous system, and the most

direct evidence to date of a possible causal connection between HHV-6A and

multiple sclerosis.

Dr. Genain's marmoset developed weight loss and paralysis with sensory

deficits after exposure to HHV-6A. Inflammatory lesions of the central

nervous system and evidence of demyelination were seen on MRI and microscope

slides of the brain tissue. However, the important finding of the study was

direct evidence of the presence of HHV-6 viral antigen within the nerve

cells of the brain stained with an HHV-6-specific antibody.

HHV-6 variant B (HHV-6B) causes roseola, a self-limited fever and

rash, in over 95% of young children by age 2. After the initial illness,

HHV-6 persists indefinitely in its quiescent, latent form in the cells of

the central nervous system, bone marrow and immune system. However, HHV-6

can reemerge and actively replicate later in life, producing new virus

particles that can cause illness. HHV-6 can reactivate in immunosuppressed

patients and cause life threatening complications, such as opportunistic

infections and encephalitis, in post-transplant patients.

The quest for a theory of viruses as a causative agent for multiple

sclerosis and other diseases has long eluded scientists. A direct link

between infection with HHV-6A and multiple sclerosis has been lacking until

now.
