2021 is an exciting time for ME/CFS science in Australia. Money is flowing. That means in time, research results will also flow. Australian labs are gearing up to do the work to deliver insights into the cause of ME/CFS and, most importantly, possible treatments.
Australia’s National Health and Medical Research Council (NHMRC) last year allocated $3.3 million for ME/CFS research. That money was split three ways, and a third of it went to a man named Ken Walder, Co-Director and Theme Leader of the Novel Treatment Discovery team at IMPACT.
Professor Walder lives in the charming seaside town of Ocean Grove in Victoria with his family and two dogs, Daisy and Jack. To find him however, you’d be best looking in the lab. Walder is the Chair of Metabolic Diseases at Deakin University, and he is most often hard at work on the Waurn Ponds campus, a sprawling collection of buildings plonked down next to cow paddocks a 30-minute drive from his home.
It’s not the most obvious place to conduct cutting-edge research, but Walder likes it.
“Compared to some of the other places I’ve been what I like about Deakin is it is a very collaborative and collegiate place,” he says.
He has enough experience to know a healthy research environment when he sees one. Walder, who is named as inventor on 40 patents and author on over 150 academic papers, has had an extremely productive career that has taken him to the prestigious US National Institutes of Health before returning to Deakin University.
One strength of Walder’s work is it will test the most energy-hungry cells.
“In the past in ME/CFS research, which has been really underfunded for a long period of time, people do what they can. People have taken white blood cells,” he says. “The problem with that is white blood cells are not a highly energetic cell. They spend most of their time just cruising around in a fairly relaxed phase.”
Professor Walder prefers to focus on cells that use most energy: skeletal muscle and brain. These are obtained not directly (you can’t obtain patients’ brain cells safely!) but by the use of stem cells.
Here’s how it works: take white blood cells, turn them into stem cells, and then turn those stem cells into either cortical networks (Walder: “We call it brain in a dish”) or skeletal muscle cells (“You look down a microscope and see the fibres contracting”).
Then they stress the cells to see how they react.
“While there may not be an obvious difference at baseline, when you stress the cells you might see that they are unable to respond appropriately.”
This process of transformation, of course, comes with some risk that the key factors are lost, Walder admits. “If there’s 20 abnormalities present and you take the cells through this process, you could lose half of them,” he says.
Still, the process has shown results in the past. “I can tell you we did this in diabetes and it worked, and we sold the intellectual property for that to a US biotech company that is still developing the technology … This work is NHMRC-funded so we are not specifically looking to commercialise anything; we are looking to find something that will help participants with the disease.”
For ME/CFS patients the most exciting aspect of Walder’s work is that it culminates in drug testing. After Walder and his team learn how to stress and dysregulate ME/CFS cells, the grant will fund the use of 1300 well-known, off-patent drugs to see which is best at restoring the cells to looking like healthy control cells.
On the negative side, there's this.Ken Walder has collaborated with Michael Maes and Michael Berk on ME/CFS work in the past. Michael Berk is also involved in this project.
There's still the problem of potentially losing what is unique about the ME/CFS cells when they are in the body of a person with ME/CFS, in the process of the cell transformation in vitro.
My understanding is that independent people working in the field think this approach has a greater chance of success and Walder has shown his team is capable of the work.
