Wayne State University presents research on vascular hypoxia in EAE. Exposure to mild chronic low oxygen was good, not bad, for EAE in mice. Dr. Haacke is not among the authors but he is also at Wayne State University. This study was a 'preclinical study' to test the hypothesis that "restoration of microvascular angiodynamics would augment tissue plasticity mitigating the extent of secondary injury and sparing cognitive decline in patients with MS."

I know it has no bearing, but I have always wondered how my wife got away with unconsciously covering her head with sheets for a large part of the night. She must be part mouse :-) .

Dr. Haacke does not have many fans in the neurology dept at Wayne State
Remember the wrath of Khan? He even used science fiction references in this editorial :)

What's interesting about this study is how it kinda PROVES that EAE is not an appropriate model for MS.
Hypoxia for rats with EAE is good, but not for humans with MS.
We already know that MS lesions show hypoxic stress--

Pertussis toxin, used in most EAE models, might be what's responsible for the protective result of hypoxia....

this is all way above my paygrade, but it looks like more proof that EAE just isn't MS.

Yeah EAE is definitely not MS.
In ischemia, mild hypoxia is good for prepping neurons for a larger event and in mitigating the impact of a larger ischemic event, so in that sense mild hypoxia is 'good' for ischemia too.

There are plenty of models in humans that show how diffuse cerebral hypoxic injury leads to white matter degredation and neurodegeneration. If MS/CCSVI creates diffuse cerebral hypoxia, you don't need rats with pertussis to model it. We can see what happens in adults with Delayed Post-Hypoxic Leukoencephalopathy

Hmmm, i thought this quote was interesting. i know this may or may not be related to CCSVI , but i find it interesting were following the EAE model of MS and yet they admit MS is unique to humans..!!

Quote:
Humans are the exclusive natural host for EBV, a finding that may explain why MS is unique to humans.

It is concluded that the ultimate test to the hypothesis of MS and EBV is the development and application of an EBV vaccine, which is predicted to eradicate the disease.
That's another good one from that abstract.
EBV impacts the endothelium and has an affinity for collagen so I think EBV could be relevant to CCSVI.
