Vitamin D receptor and polyomaviruses?

This blog post is just notes right now. Do polyomaviruses use vit D receptors to get to the ER? 

Alopecia and HLA-C (mailbox for the ER)

(there are other forms of alopecia we are looking at this HLA-C group)

Multiple sclerosis and HLA-C (not the MS triggered by zoster using HLA-B)

Polyomaviruses infect the endoplasmic reticulum (BK JC viruses)

the docking sites for the VDR receptor at the cytosol are on the endoplasmic reticulum (using fluorescent bp-calcitriol)

vit D receptor

"calcitriol receptor, also known as the vitamin D receptor (VDR) and also known as NR1I1 (nuclear receptor subfamily 1, group I, member 1), is a member of the nuclear receptor family of transcription factors.^[3] " from wiki

Is there an overlap of MS and alopecia? if they are both triggered by a polyomavirus there might be

the VDR (vit D receptor) gene increased the risk specifically for progressive multiple sclerosis

MS triggered by hepatitis B vaccine

Alopecia triggered by hepatitis B vaccine? it is a controversy

(note there is more than one type of MS)

Alopecia and MS?

I've had Alopecia universalis since I was 12 (I'm nearly 30 now) so since I was young I have not had a single hair on my head or body. I lost all my eyebrows, eyelashes ... Everything! Although a big shock at first, I am now totally comfortable with my Alopecia and I understand that my immune system attacks my hair follicles, not allowing me to grow any hair.

The strange thing I've found is over the past 8-12 months I have started growing hair! I've not had a single hair on my head or body in over 18 years and now all of a sudden I have eyebrows, eyelashes, under arm hair (not liking this lol) and a little hair on my head.

Do you think it's possible that if my problems are due to MS and I have had a relapse, that maybe my immune system has been drawn to attacking another part of my body (for example my brain!) and so my hair follicles have been given a break for a while?

Sorry if this sounds stupid! It's just you don't know how weird it is for my to suddenly be growing hair after all these years .

Would love to hear people's thoughts on this :)
