Pregnancy is an important issue with regard to MS, so we try and post the research even if we have nothing much to say

Education PNS and CNS axons

Peripheral nervous system and central nervous system nerve axons

A nerve that we see in the peripheral nervous system (PNS) or a white-matter ‘tract’ in the central nervous system (CNS) is composed of many axons. The axons are elongated extensions of individual nerve cells, and they are structures specialized for signalling over distance. Let me try to explain.

When you see a peripheral nerve in a limb, from the outside, it is protected by a robust sheath, made of connective tissue. This sheath gives the peripheral nerve a degree of robustness and stretchiness. 

Peripheral nerves are unharmed by being stretched a bit, and to a surprising degree they move or glide past adjacent tissues for example at the carpal tunnel, when we move and bend our limbs, quite normally. Held within that stretchy coating are the nerve axons, either sending signals towards the spinal cord or the brain, in the form of sensory input, or away from the spinal cord or brain to provide some motor function be it muscle contraction, or secretion. 

The same is not true of nerves protected inside the skull and spinal column. 

The nerve fibres within the central nervous system are not covered in a stretchy coat in the same way as in the periphery, and these axons are usually to be found in tracts, notable for their white appearance in dissection, the ‘white matter’ that most people have heard about. These nerve fibres are known to signal over distance by sending nerve impulses from one part of the CNS to another, or also down the spinal cord to control our body movements. 

They are embedded in the three dimensional anatomical structure of the brain and spinal cord. Like the axons in peripheral nerves they are accompanied by nearby blood vessels and capillaries that provide the necessary oxygen and glucose that allow them to function.

The median nerve (in red) is an example of a long peripheral nerve innervating the arm and hand. It is a mixed nerve, with sensory and motor function. It innervates the hand via the carpal tunnel at the wrist. The main stem of the nerve is flexible and moves around quite a lot as we move and bend our arm. Central axons in the brain or spinal cord are not able to move independently of the tissue around them, and are held fast

HSCT and T cells and MS and memory B cells

What cells are important to target in HSCT?

TeamG in the News...used for Crowd funding

ProfG and DrK were in the media yesterday as they launched their #Thinkhand campaign.

Yep this is old news on the blogsphere, but the Evening Standard (Local London Newspaper) picked up the story and pulled a fast one

Putting the CART before the horse: could CAR-T cells be a last-resort therapy in MS to rival HSCT?

First off, apologies my long winter hibernation from the blog. As you may have gathered (if anyone is paying close attention to my blogging habits) I'm no longer full-time at BartsMS, and have been working in mental health down the road at Mile End. There are loads of interesting things to say about the overlap between MS and mental health, lots of which have been discussed before on the blog. 

#ThinkHand: Today is MS Hand Awareness Day

We are hosting our #ThinkHand Awareness event tonight. The good news is that will be there to help promote the campaign. The following are some YouTube clips, from their reporters, explaining the campaign and how you can help. 

Thank you for helping and spreading hope for the million-plus people who have MS and are using a wheelchair.

Barts Health CSF Neurofilament light chain (NfL) request

As promised, any clinician based in the UK can request the neurofilament light chain for Multiple Sclerosis. Your hospital laboratory would need to discuss the transfer of you CSF sample to our lab:

Dr David Holden
Centre for Neuroscience and Trauma,
Queen Mary University of London,
4 Newark St
E1 4AT


A sample request form is below:

The final report that you receive will look something like this:

If there are particular questions with regard to sample volume, storage and transport Dr Holden will be able to answer them.

Vitamin C for myelination

What has vitamin C got to do with MS?

Our Prime Minister has the decency to send her apologies

We are hosting our #ThinkHand awareness event tomorrow night. We were hoping to get Theresa May to attend and endorse the event. At least she responded. JK Rowling didn't even acknowledge our invitation. Very poor form?
