Thanks Bromley— The article states:
Quote:
Oestrogen turns up the adaptive immune system, improving the ability to fight off infection but making it more susceptible to auto-immune disease. In males, testosterone appears to suppress it.

I must say from my reading about hormones I am of the impression testosterone may reduce the susceptibility of being diagnosed with MS and estrogen definitely seems to be anti-inflammatory. I don’t know anything though about the innate/adaptive immune systems and have no earthly idea why the adaptive immune response in women would make them more susceptible to auto-immune diseases. I’m curious to learn from the auto-immune experts why that would be the case. It’s going to take a lot to convince me that MS is auto-immune. :wink:

That estrogen is anti-inflammatory and neurprotective is reviewed in part in this abstract, From clinical evidence to molecular mechanisms underlying neuroprotection afforded by estrogens . Another abstract highlights the role of mitochondria in neuroprotection afforded by estrogen. Mitochondria play a central role in estrogen-induced neuroprotection Note:
Quote:
The discovery that 17alpha-estradiol, an isomer of E2, is equally as cytoprotective as E2 yet is >200-fold less active as a hormone, has permitted development of novel, more potent analogs where cytoprotection is independent of hormonal potency…….
This therapeutic strategy is germane not only to sudden mitochondrial failure in acute circumstances, such as during a stroke or myocardial infarction, but also to gradual mitochondrial dysfunction associated with chronic degenerative disorders such as AD, PD and HD.

Mitochondrial dysfunction, as already posted elsewhere, may be real relevant to MS too. Mitochondrial Dysfunction as a Cause of Axonal Degeneration MS

Enough about estrogen. One of these days Bromley I’ll have a post that says “This One’s For You”…..I really do appreciate your posting info you think I’d be interested in. I am.
