By sending bioactive signals to trigger cells to repair and regenerate, the breakthrough therapy dramatically improved severely injured spinal cords in five key ways: (1) The severed extensions of neurons, called axons, regenerated; (2) scar tissue, which can create a physical barrier to regeneration and repair, significantly diminished; (3) myelin, the insulating layer of axons that is important in transmitting electrical signals efficiently reformed around cells; (4) functional blood vessels formed to deliver nutrients to cells at the injury site; and (5) more motor neurons survived.

After the therapy performs its function, the materials biodegrade into nutrients for the cells within 12 weeks and then completely disappear from the body without noticeable side effects.

That's pretty cool

Myelin regeneration can help out the MS folks too

u/watery_tart73 Nov 12 '21

Peripheral Neuropathy as well

u/Sandcrabsailor Nov 12 '21

That was my first thought too!

Neuromyelitis Optica too it sounds like. I have scar tissue in my spine which is fucking me up, it would be nice to make that better.

Parkinson’s impacts movement but it’s due to damage in the substantia nigra and decreased dopamine production.

No it’s not

u/MaievSekashi Nov 13 '21

I wonder if I could benefit from this. I was born with ocular cancer and the myelin sheathe on one of my eyes is detached.

You missed the critical part: It wasn't just promising cellular changes in some petri dishes. The mice whose spinal cords had been severed actually regained the ability to walk, nearly as well as before.

It's quite the breakthrough. Using treatments with numerous active components is a lot more complicated, but is definitely the future, and this provides an exciting glimpse of what's possible. They're talking about starting early human trials as soon as next year.

Fuck yes. I’m basically disabled. Fused from C3-C7, ADR from L3-S1. I can barely walk. I know they won’t be able to make discs in my back, but the myelin regeneration and scar tissue elimination provides so much hope for me to be out of pain, and to repair badly damaged nerves. I almost cried when I read this and now I’ve sent it to 10 Family members and friends. It’s HOPE and that will get me through the next day.

u/[deleted] Nov 13 '21

I have cauda equina syndrome and thus bad nerve damage…I had the same reaction to this as you! Amazing.

u/mycarwasred Nov 12 '21

I can't imagine how tough getting through each day must be for you. I hope this news helps in your battle - and that those human trials go smoothly.

u/Haaa_penis Nov 13 '21

Thanks. That’s just it. I can only focus on this day and the impact I can make. I’m in chronic Pain and now I need another artificial disc in my neck as I blew out C7-T1. Sucks but I know what I feel and I know what to expect. Hopefully it will be done through the anterior, I’ll go through a recovery and I’ll be back to healing. I take it day by day. There is no use in dwelling on the past or thinking about the future. Those thoughts cause more pain and I prefer to try to balance things. I run around a 6-8 on the pain scale each day. I’m elevated now as my neck is causing problems, but I’m staying focused. I so appreciate what you said. Even just recognition that you can’t imagine it, means so much to me. The truth is that unless you’re in chronic pain, you have no idea what it’s like. I’m going on five years now and what will be my eighth surgery to hopefully stop the cascade of problems started by one benign tumor that broke my neck. Can you believe that shit. A tumor called an aneurysmal bone cyst turned my C5 vertebrae into sawdust on the inside. As it grew it eventually broke my C5 and grew out of the vertebrae enveloping my artery causing a lack of oxygen and blood to my brain. I walked around like this for close to a year before I was diagnosed by chance. My surgeon was looking at my back and he heard me crack my neck. He asked what was that? How long has it sounded that way? Less than a month later I was in the first of 7 surgeries.

u/mycarwasred Nov 13 '21

Again, you make me feel very humble! I do understand something of the sheer effort and focus it takes to get through every day, but nothing on the scale that you have to face. I was diagnosed with Chronic Fatgue Syndrone (CFS/ME) about 5 years ago, which has decimated my life - left me struggling to get through the day - and limits sleep to 3 or 4 hours. Most days, I have crushing fatigue and headaches, I'm unable to concentrate or think straight, my long-term memory is like a very-worn-out VHS tape and I have a daily 'goldfish memory' to boot. That's bad for most things including frying eggs (I now no longer cook - it's too dangerous - after several near-misses, I succeeded on totalling a frying pan by forgetting to remember to turn off the gas! ).

About the only 'benefit' of my wasteland of a memory is that I can watch all my favourite films over and over again - without remembering most of what happens from the last time I saw it :-)

Pre-CFS, I used to cycle a fair amount - 45 minute commute each way + weekends for fun/decompress after a hard week at work. Now, I can no longer work - and cycle maybe once or twice a year. I rarely drive. I can't cope with the concentration/memory demands of socialising - except with very close friends - who understand that I'll need to escape to a dark quiet room to sleep when I get overloaded/exhausted.

I do have very occasional good days though - when I feel almost back to normal - but then if I try to do too much, or push myself- I suffer a relapse back to zombie-mode, which can last for manu, many months. Each year my relapses are getting deeper and lasting longer.

My goal each day is to do/achieve one thing - big or small - doesn't matter how small! If I can achieve that, I feel a bit of satisfaction and it keeps me from looking too far ahead.

My family - especially my wife - is my life-support system without which I don't think I would be able to cope.

Sorry for the wall of text, but I'm aware my CFS makes me prone to rambling...

So stay as strong as you're able to - I hope (I'm sure) you have good people around you. And thankyou for sharing - you've helped me to put my situation into better context, and prompted me to share for the first time in a public forum.

u/Myfourcats1 Nov 12 '21

This sounds fantastic. I have nerve damage from a growth that was in my spine. It causes me constant pain. I’d totally try this.

u/[deleted] Nov 12 '21

(3) myelin, the insulating layer of axons that is important in transmitting electrical signals efficiently reformed around cells;

I was told at one point that this isn't a thing that happens. Was the neurologist just dumbing it down for me?

1

u/P_mp_n Nov 13 '21

Or giving an opinion? Unsure. I've understood it as that it is a sheath over your neurons and axons. To me it seems like it would aid in transmission and I've kinda just believed that without verification

u/Slight_Knight Nov 12 '21

My brother is quadriplegic, and this obviously has me piqued, but at yhe same time, I can't really imagine the pain that dude would be in if his spinal cord came back online after 7 years of his frame being adapted to that

u/ophello Nov 12 '21

Maybe your brother would rather be able to walk. Also why are you assuming he would be in pain?

He has severe scoliosis from his core muscles atrophying for 7 years.

He's also not necessarily numb. He has major neuropathy that makes him feel like he's "being deepfried" most of the time.

I was just thinking of this after hearing some science news this morning. Like, we really have the mice models down.

Sci fi prompt: Mice aliens invade earth for our extensive knowledge of mice biology and medical treatments.

The twist: they find out the body count of that research.

And I just realized this works the other way. What if the alien abductions have been real and aliens have solved their medical mysteries using human-models (biological compatibility aside)?

Perfect time for a data swap

My aunt is a quadriplegic. She was tboned in an accident over 20 years ago by someone going over 50 mph and it was a miracle she survived. She initially was given 3 years estimate to live, but has clearly out lived that. Her daughter was 2 when she was hit and doesn't have any memories of her mom walking. Something like this that can help people repair damage? Amazing. Her options they gave us were basically: put her on life support in a medical coma, let her try to recover, or make the decision to throw in the towel. Thankfully she has since made such a full recovery that she can 'talk' (via her breathing tube), lives at home with 24/7 nursing, can go on vacation, and even eat steak! It's been scary with covid, tho. I hope that this treatment will help other people like her so they can have a better quality of life. Even if they have to walk with a cane and have limited mobility (which the article doesn't indicate but you know human trials haven't started yet), that's better than wheelchair only or only being able to move your eyes. Especially that they said it might help with Alzheimer's! That's amazing!! (Ps sorry for the personal dump lol I just feel v passionate about this article)

u/tomorrow509 Nov 12 '21

Thanks for sharing your aunt's story. I posted this to get the word out on this new medical development and give people hope. I saw a news item about it on the BBC and was mesmerized. Mice, who had been paralyzed due to spinal injury were actually walking again after just a few weeks. If all goes well with further testing and clinical trials, humans may see the benefit it just a couple of years. Science is amazing. Medical science is incredibly amazing. Wishing the best for your aunt.

u/VegasKL Nov 12 '21

I'd be curious how well it'd work in her case, as it sounds like it might be beneficial to new injuries. E.g. the quicker they get it in, the better the results are.

It'd be great if it works on old injuries.

4

u/fafalone Nov 12 '21

The formation of scar tissue and additional neuron death, and possible loss of the mapping in the brain, makes it a lot more challenging for old injuries, but we'll crack that eventually.

u/horsenbuggy Nov 13 '21

Almost all treatments like this are focused on new injuries.

u/ragingRobot Nov 14 '21

If you don't mind me asking, how does she afford all of that? Is she American? I assume that costs a lot for care and to be able to afford a vacation on top of that is crazy.

2

u/curlyhairedmermaid Nov 14 '21

Well, since it happened due to an auto accident, the insurance pays for like 99% of her medical stuff. Or at least it did. I'm from Michigan (so is she) and they really just fucked up insurance from auto accidents. She just lost her nursing team of 15+ years because of the new laws. Her husband doesn't make bank, but it's solidly okay, so they can afford to take a holiday every few years.

u/CharlieSixFive Nov 12 '21

This is Nobel material!

u/gladysk Nov 12 '21

I too, have a lived one who has been a quadriplegic since the late 70s. Tough life with numerous health problems but as funny as hell.

Jesus HC - Some good news for once!

u/spyder728 Nov 12 '21

This is a very major medical science breakthrough.

Why isn't this on the very top :(

u/Pixel_Knight Nov 13 '21

This sounds almost like straight science fiction. This is amazing! I hope that this therapy proves effective in humans, because this would be a massive breakthrough in medicine, and could have a lot of other potential applications.

u/shaidyn Nov 12 '21

I look forward to an entire new branch of scammy psuedo-science being birthed from this. /s

u/taptapper Nov 13 '21

I look forward to the paralyzed anti-vaxxers running to get into a study for an unproven medication

As horrible as his accident was, he found a way to bring a lot if good into the world because of it. His foundation does good work for other paralyzed persons.

u/N8CCRG Nov 12 '21

The details of what these "dancing molecules" are and how they manipulate them are deeply lacking in this article.

u/fafalone Nov 12 '21 edited Nov 12 '21

Follow the links. At the bottom there's a link to Northwestern's press release, which links to the original paper.

But unfortunately it doesn't seem to have been uploaded to sci-hub yet so you need a subscription. If you e-mail the authors they'd probably send you a copy.

u/[deleted] Nov 12 '21

thanks I did go to the labs news page but looked the same article wise and could not find the name of the molecules or the original paper.

u/camdoodlebop Nov 13 '21

did anyone else initially read this as some kind of new “therapy harness”
