Vitamin D News--it boosts remyelination!

This just in today----

Vitamin D boosts remyelination
Researchers at the University of Cambridge set out to find what controls oligodendrocyte progenator cells (OPCs) ability to differentiate and create myelin--and discovered that it is Vitamin D which binds and activates vitamin D receptors and controls myelin sheath regeneration.  In fact, remyelination of axons is impaired when Vitamin D receptor (VDR) is blocked.  When Vitamin D was added to the brain's stem cells, production of OPCs increased 80%.

In case we need even more proof that Vitamin D is an important part of MS recovery,   I'd like to round up the latest crop of papers, published in 2015,  linking higher Vitamin D levels with better health for people with MS.


Vitamin D prevents brain atrophy
Researchers at Yale University discovered that higher serum levels of Vitamin D is linked to higher levels of gray matter in the brain, and lower rates of tissue loss, or brain atrophy, in MS. They looked at 65 pwMS and measured brain volume on MRI.   The strongest correlation was between low Vitamin D levels and brain atrophy.

Vitamin D strengthens endothelial cells
A study from the University of Utah found that Vitamin D stabilizes the endothelium and strengthens the vasculature.  It acts directly on endothelial cells to inhibit vascular leak.  Since inflammation and "auto-immune" reactions are a function of plasmic particles leaking into tissue and setting off an immune reaction (in places like the gut or blood brain barrier)---finding ways to strengthen endothelial cells is vitally important.

Higher Vitamin D levels means more time from RRMS to SPMS conversion
Researchers in the Netherlands found that there was an association of low Vitamin D levels at the start of diagnosis of MS which was linked to an early conversion to SPMS.  Those with higher Vitamin D levels took longer to convert to SPMS.

Higher levels of sun exposure decreases MS risk
Australian researchers find the UV ray exposure is associated with lower MS progression rates and disease activity, through both Vitamin D and non-Vitamin D pathways.  UV rays modify and regulate immune cells.

Pretty impressive research!  But are the benefits of Vitamin D for those with MS simply recent news?  Not really.  Dr. Ashton Embry's Direct-MS site is where Dr. Terry Wahls and many of us first heard about the connection between Vitamin D and improved MS outcomes almost a decade ago.  In fact, Direct-MS funded two trials on Vitamin D, and both had very positive results published in 2009 and 2010.  Thanks to the Embry Family for funding and pushing this research!

I've been writing about the therapeutic powers of vitamin D on the vascular endothelium since 2008.  I also included sunshine and UV rays.

Here's a blog post from 2010, where I explain how Vitamin D provides "vasculoprotection" and prevents brain atrophy.
http://ccsviinms.blogspot.com/2010/07/vitamin-d-provides-vasculoprotection.html

Here's some completely anecdotal evidence from our home:
Jeff's Vitamin D level has stayed around 70ng/mL since he began supplementing and getting rays, and he continues to do well, with no MS progression or disabilities.  His Vitamin D level was at 15ng/mL when diagnosed for MS in 2007.  We had to pay for his first D3 test, since it wasn't covered by insurance. Our doctor asked why we wanted his D3 levels tested, and I shared the Direct-MS site with her.  Since then, our insurance company has seen the light (pun intended!) and covers yearly testing of D3 levels.  As for me, I hadn't been taking any D3 supplements, but that's recently changed. This past spring, my level was 17ng/mL and I was put on a high dose (50,000IU) weekly dosage for 2 months.  My levels are now good at 65g/mL and I maintain that with 4,000IU daily. I have much less arthritis pain and more energy.  There's a link to optimizing Vitamin D levels for healthy people, too.

Also know that there are many environmental factors which can contribute to a lower Vitamin D status- including obesity, older age, living in a more northern latitude with less UV exposure, smoking, skin color and pigmentation, micronutrient and mineral deficiencies (especially magnesium and zinc) and genetic mutations on the Vitamin D receptor (VDR) gene---and all of these factors may influence your serum Vitamin D levels.

So, while this info on Vitamin D is not new or ground-breaking for most following MS research, it is further building on the foundation.  Let this be a shout out to all people with MS.  Find out what your Vitamin D levels are, and make sure you optimize them!  This doesn't always mean simply taking a supplement.  It might involve more sun exposure or phototherapy, quitting smoking, losing weight and eating a whole food diet.  Work with your healthcare provider to establish the best program for you, and get those numbers up!  And don't forget, it's not about one pill or supplement, it's about living a new life.

Be well,
Joan

New research on UV rays and MS symptom reduction

Most of you know about my suggestion that people with MS seek UV ray therapy, by spending ten to fifteen minutes in sunshine daily, or using UVB phototherapy in less sunny locales.  Not just to maintain healthy Vitamin D levels, but to boost levels of Nitric Oxide (NO).

I first wrote about this in the Endothelial Health Program in 2008.  We make sure Jeff gets his daily rays (as well as daily exercise and phytonutrients.)  Here's the program again, for new readers.

In the following note, I wrote about the ground-breaking, Noble prize winning research of Dr. Furchgott--he discovered the importance of Nitric Oxide and the process of "photorelaxation" or the vasodilation that occurs thanks to UVB rays.

Dr. Furchgott discovered the process of photorelaxation over 40 years ago.  What he noted in the lab was that exposure to UV rays changed the endothelium, encouraging nitric oxide production and vasodilation of arteries.

It would be decades later Dr. Richard Weller discovered exactly how UVB rays released nitrates via our skin--and explained how this could explain the connection of latitude and heart disease.

Dr. Richard Weller of Edinburgh University reports on research finding that when skin is exposed to UV rays for 20 minutes, vasodilating nitric oxide is released.  This effect is independent of vitamin D levels--and may explain why even if D levels are raised by supplementation, the full benefit is not received.

So, I was understandably interested to see a group of neurologists looking at the effect of UVB rays on people with MS.  

http://www.ncbi.nlm.nih.gov/pubmed/24771567

The neurologists first look at the murine model of MS, called EAE.  But, as Dr. Weller explains in his wonderful TED talk---mouse models do not work when we're discussing UVB rays and their affect on humans....because mice do not process UV the same way we do.  They do not have the same skin.  After learning this, Dr. Weller did all of his research on his student lab assistants, and as he quips, "They are cheap, and no one pickets you saying, save the lab assistants!"

Here's Dr. Weller on his discovery of what UVB rays do in humans.  If you haven't watched this TED talk yet--please do!  You'll thank me later.  (For a scientist, he's really entertaining!)

Alright, back to the new paper from the Department of Neurology in Munster, Germany, which is titled:
UVB light attenuates the systemic immune response in CNS autoimmunity.

http://www.ncbi.nlm.nih.gov/pubmed/24771567

Here's what they saw in humans....an anti-inflammatory response in MS due to UV ray exposure.

Additionally, patients with relapsing-remitting MS were treated with narrowband UVB phototherapy. Immunomodulatory effects were examined in skin biopsies, serum samples and in immune cells of the peripheral blood. 

Results: Regulatory T cells (Tregs), which are induced locally in the skin-draining lymph nodes in response to UVB exposure, connect the cutaneous immune response to CNS immunity by migration to the sites of inflammation (blood, spleen, CNS). Here, they attenuate the inflammatory response and ameliorate disease symptoms. Treg-inducing tolerogenic Dendritic Cells (DCs) were further necessary for induction of this systemic immune regulation by UVB radiation since ablation of Langerhans cells abolished the UVB-induced phenotype. MS patients treated with UVB phototherapy showed an increase in induced Tregs and tolerogenic DCs accompanied by the downregulation of the T-cell effector cytokine interleukin (IL) -21. The treatment further induced elevated serum levels of vitamin D. Interpretation: Local UVB radiation of the skin influences systemic immune reactions and attenuates systemic autoimmunity via the induction of skin-derived tolerogenic DCs and Tregs.

Now, in English :)  When people with MS were exposed to UVB rays, their lymph nodes responded by sending out regulatory t cells to areas of inflammation.  These Treg cells are"good guys."  They calm inflammation.  And Tregs are enhanced by UVB rays via skin cells.  People who got UVB rays had a reduction of MS symptoms.  No prescription necessary.

That's right---neurologists are telling us that UVB rays helped pwMS! 

In fact, we already know this happens.  It's why UV ray phototherapy is used for patients with psoriasis.  UV light increases Treg cells, which in turn reduce inflammatory cells.
http://www.medscape.com/viewarticle/814678_5

How, exactly, does this happen?  Although it's not mentioned here, other researchers have explained it ...Wait for it.....it's Nitric Oxide!

http://www.sciencedirect.com/science/article/pii/S1089860312000870

http://www.jimmunol.org/content/early/2013/05/28/jimmunol.1202580.abstract
http://www.ncbi.nlm.nih.gov/pubmed/23720815

Nitric Oxide (NO), the marker of endothelial health, is also responsible for helping those treg cells leave the lymph nodes and head to sites of inflammation, calming MS inflammation and symptoms.  The same Nitric Oxide that Dr. Weller has shown to be released from human skin cells by UVB rays.  It's all connected.

The endothelium is the interface between our vascular and immune systems.  The lining of our blood vessels connects every inch of our body.  Nitric Oxide is essential for our health.  And we can boost NO with nutrition, lifestyle, exercise, meditation, and sunshine.

http://www.ccsvi.org/index.php/helping-myself/endothelial-health

I continue to hope that neurologists will reach out across the aisle, and work with endothelial specialists, to understand the intricate interplay between our vascular and immune systems. To move beyond the credo of EAE and autoimmunity, which may exist in mice, but not in men.  To understand the connection of the heart and the brain, via the vasculature.  The ISNVD is looking at this connection, and they want neurologists to join them.

It's all there.

Sunny days ahead,

Joan
