Final 12 months, Jette Oppelstrup, 49, invested in a rest room on the bottom ground of her townhouse in Herlev, a suburb of Copenhagen. Within the bottom-left nook of the mirror above her sink within the new rest room are two stickers that learn: “FUCK PARKINSON, NEVER GIVE UP”.
Oppelstrup was identified with Parkinson’s illness in 2017. The illness not often strikes folks underneath the age of 60, and is greatest identified for afflicting folks with seen tremors on their palms and slowing their motion. Sooner or later, she might not have the ability to stroll upstairs to her outdated rest room as typically as nature calls.
However for folks residing with Parkinson’s at present, opposite to only a decade in the past, the phrase “by no means hand over” is now not only a motivational saying. A brand new Parkinson’s remedy that makes use of stem cells to artificially create new dopamine-producing nerve cells is anticipated to enter medical trials on human sufferers later this 12 months. Due to the lengthy course of Parkinson’s, many sufferers who obtain a prognosis at present might dwell lengthy sufficient to be eligible for this type of remedy and discover their lives spared from the tough superior levels of the illness—and maybe see their motor operate restored.
That's, after all, if the remedy is profitable.

A Decade within the Making
Almost a million individuals are residing with Parkinson’s illness in the USA alone, in accordance with the Parkinson’s Basis. About 60,000 individuals are identified with Parkinson’s every year, and that quantity is anticipated to rise to 1.2 million by the tip of this decade. It's the quickest rising neurological dysfunction on the earth, with the worldwide variety of identified folks doubling from 3 to six million folks between 1990 and 2015. If this improvement continues, the variety of instances will once more have doubled by 2040.
“If the speed at which Parkinson’s progress continues, we’re going to outgrow the capability to have the ability to deal with all the penalties of letting a persistent neurodegenerative illness go unchecked,” Michael S. Okun, a neurologist on the College of Florida and one of many world’s main Parkinson’s scientists, instructed The Every day Beast.
After a long time of analysis, what we all know to this point is that Parkinson’s is brought about when dopamine-producing nerve cells within the mind die too quick. Usually known as the “blissful hormone”, dopamine is important for relaying indicators from the mind that give orders of motion to completely different physique components. A dearth of dopamine will trigger tremors and slowed motion. These signs solely worsen over time, and make it extraordinarily troublesome to do even the only actions within the late levels of the sickness.
And Parkinson’s can result in cognitive results as effectively, reminiscent of short-term reminiscence loss, difficulties with staying targeted, and challenges with impulse management.
For all these causes, “it’s laborious to really have religion that a remedy will likely be developed in time,” Oppelstrup instructed The Every day Beast. “However I’ll be the primary in line for the trials. I simply gotta work out the place to enroll.”

The brand new trials are the end result of greater than 10 years’ work by scientists at Lund College in Sweden and the College of Copenhagen in Denmark, together with assist by the Danish pharmaceutical large Novo Nordisk. It raises large hopes that we'd lastly have one thing to remodel the lives of hundreds of thousands who're residing with Parkinson’s.
The remedy itself works by taking stem cells from surplus fertilized eggs from in vitro fertilization (IVF) clinics. These cells are derived from the earliest levels of fetal improvement, which implies they're able to be grown into every other sort of cell discovered within the physique. That features the dopamine-producing nerve cells which are misplaced in Parkinson’s illness.
“What we then do is add a sequence of very particular proteins—so-called progress elements—in order that the cells become the mandatory dopamine-producing nerve cells within the petri dish,” Agnete Kirkeby, a College of Copenhagen neuroscientist who’s helped pioneer the brand new remedy, instructed The Every day Beast. “Then the cells are surgically inserted into the mind utilizing a particular sort of needle, and can hopefully produce dopamine rather than the affected person’s useless nerve cells.”
In response to Kirkeby, the group has been testing this remedy on animal fashions since 2012. The implanted cells have been proven to outlive transplantation in rats and talk with the physique’s different cells to revive dopamine manufacturing—and by extension, motor operate.
The method of growing such a remedy is long-winded as a result of the quantity and sequence of progress elements used have to be extremely exact to be able to develop the stem cells into nerve cells. Discovering the proper mixture of progress elements comes right down to an knowledgeable version of trial-and-error.
One other remedy generally known as deep mind stimulation, the place implants are used to ship direct electrical stimulation to sure components of the mind, has already been profitable in delaying or assuaging the bodily signs of Parkinson’s by as much as a number of years. Since neurosurgeons have already established a secure surgical technique for implanting these electrodes, they'll use an identical technique for safely slicing into the mind and delivering the stem cells, defined Kirkeby.
“We hope to start the trials this 12 months, and in the event that they go effectively, the stem cell remedy can hopefully hit the cabinets and be used to deal with Parkinson’s sufferers as quickly as eight to 10 years from now,” she stated. If the remedy is authorised after the primary trials, the plan is for Novo Nordisk to maneuver the remedy into larger-scale trials.
It’s not merely that the remedy might present reduction to hundreds of thousands of individuals around the globe. As a result of Parkinson’s illness has such an extended pure historical past and sufferers could also be severely debilitated for years and years, being a caregiver is a full-time job. Many might must take day off work to care for his or her family, and the bodily toll the care takes on their our bodies might result in future well being issues of their very own.
“We face a difficulty that if we don’t take care of it, we're going to see catastrophic penalties. Not simply from patient-suffering, however financial penalties and the power of our health-care methods to face up,” stated Okun.
Excessive Hopes, Reasonable Expectations
Nonetheless, though there’s fairly a little bit of hope about what the brand new stem cell remedy might do for sufferers and their households alike, there’s a historical past of recent therapies really fizzling out throughout rigorous testing.
“It occurs very not often that we truly treatment an sickness,” Ray Dorsey, a neurologist on the College of Rochester Medical Heart, instructed The Every day Beast. “Much more typically we discover a solution to stop them. Take into consideration what it takes to treatment somebody with Parkinson’s after half of their nerve cells have died. I simply suppose we have to take a cool, rational have a look at this and say that that’s actually laborious to do.”
And whereas now we have a transparent image of the dopamine connection, now we have little or no understanding about precisely why nerve cells will begin to produce much less dopamine in sure folks. Age is clearly an enormous correlation, and a few analysis has pointed to associations with using sure pesticides and metals because of the disproportionately excessive variety of rural inhabitants who come down with Parkinson’s. Some scientists speculate that if we lived lengthy sufficient, all people would ultimately develop Parkinson’s since cells start to die attributable to outdated age.
Karin Christiansen, 57, and her husband Keld Hansen, 65, dwell in Odense, Denmark’s third-largest metropolis. In 2018, Karin was identified with Parkinson’s illness after a number of years of residing with signs, together with robust ache in the fitting leg and having a tough time holding stability.

“The worst half is the worry of disappearing in my thoughts,” Christiansen instructed The Every day Beast, referring to the chance of growing dementia as a long-term symptom of Parkinson’s. Although she is a participant in closed trials for one more new experimental remedy that has helped considerably to alleviate her ache and regain management over her bodily capabilities, she has a tough time believing that any remedy might “save” her in time—not even stem cells.
“I’m scared that when you’ve been sick, it’s laborious to return to regular once more,” added Hansen. “It’s her mind that’s being destroyed, and I’m unsure that’s attainable to revive.”
So although the rats might quickly be swapped with people, and the stem cell remedy could also be proper across the nook, Karin tries to not pay an excessive amount of consideration to it. Getting her hopes up, in all probability, would simply finish in disappointment, she stated.
As a substitute, she just isn't a lot wanting ahead to what remedies like this would possibly do for her—however relatively what they could do for the following generations.
“It’s most likely largely the people who find themselves identified sooner or later who will likely be fortunate sufficient to learn from it,” stated Christiansen.
