How Do Mesenchymal Stem Cells Work In The Body
Mesenchymal stem cells utilize their self-renewal, immunomodulatory, anti-inflammatory, signaling, and differentiation properties to influence positive change within the body. Mesenchymal stem cells also have the capacity to self-renew by dividing and developing into multiple specialized cell types present in a specific tissue or organ. Mesenchymal stem cells are adult stem cells, meaning they present no ethical concerns, MSCs are not sourced from embryonic material.
Why Should I Participate In A Clinical Study
We can only reach breakthroughs in treatment and care if people participate in the studies.
Participating is safe and can help you
Every clinical study is reviewed thoroughly before your doctor asks you to participate. Clinical trials carry some risks, but your doctor is required by law to explain the risks to you clearly and make sure that you understand them. If your doctor tells you about the risks of participating in the study, ask yourself, What are the risks of not participating in the study? Most of the time, if you balance the possible benefits from participating against the risks, it is about the same as the risks of not being in the study.
On the other hand, the study may be of a new drug or treatment that could help you. If you dont participate, it may be years before you have a chance to try that drug.
Some people do not participate because there is no guarantee they will get the experimental therapy they might get the placebo. Again, think carefully about the risks and benefits of entering the study and getting the new treatment, entering the study and getting the placebo or not entering the study at all.
Your participation can help others
If you have PD or any other disease, the drugs, procedures and therapies you use now were scientifically tested, likely by thousands of volunteers. Participating in a clinical trial is your way to pay it forward for people diagnosed with Parkinsons in the future.
Medications For Parkinsons Disease
Currently, the most common medication for managing the symptoms of Parkinsons disease is a drug called levodopa. The brain converts levodopa to dopamine, helping replace the neurotransmitters loss.
Since levodopa can cause nausea, the medication is almost always administered with a companion drug, carbidopa, which manages stomach upset and nausea symptoms.
Unfortunately, levodopas absorption is inconsistent because it takes a long path from the small intestine through the blood to the brain. The inconsistency can lead to a rise and fall in the brains dopamine levels.
Additionally, the treatment becomes less effective over time, as the cells that convert levodopa to dopamine continue to decline. There are several other medications aimed at reducing Parkinsons symptoms. However, they all have some limitations.

Top Ways To Treat Parkinsons Disease
This content was developed in partnership with the Parkinsons Foundation.
Every person living with Parkinsons disease experiences symptoms, disease progression and treatments that are unique to them. There is no single treatment plan that works for everyone.
The most common way to treat and manage PD symptoms include medications, exercise, rehabilitation therapies and surgical procedures. Treatment plans should be tailored to respond to an individuals symptoms and personal circumstances. While there is currently no cure for PD, the goals of treatment are to minimize symptoms and improve overall quality of life.
Exercises For Parkinsons Disease
Exercise is critical to maintaining balance, mobility, and strength for those with Parkinsons. When using physical activity to manage Parkinsons symptoms, patients should combine aerobic, strength, balance, agility, and flexibility exercises.
Many activities incorporate these elements, such as yoga, biking, running, dance, and Pilates.

What Is Parkinson’s Disease
Parkinson’s Disease is a degenerative nervous system condition that affects one’s movement. Symptoms often start quite gradually, with minor issues such as small tremors within the extremities . Currently, there is no cure for Parkinson’s Disease but certain medications do have the capacity to help manage symptoms. Some doctors may also recommend surgery to address certain symptoms, which involves regulating certain areas of the brain.
New Form Of Drug Helping Some Patients With Parkinsons Disease
For more than 40 years, a drug called levodopa has been the most effective treatment for the uncontrolled movements associated with Parkinsons disease. Many Parkinsons patients have taken a pill form of the medicine also known as L-dopa for years to control their motor fluctuations.
But the pills can lose effectiveness over time, greatly reducing their value for people in the later stages of the disease.
Now theres a new form of the drug that is making a positive difference for some Parkinsons patients. Duopa is a drug thats delivered continuously by a pump system instead of pills.
This takes care of the fluctuations in the movement symptoms that advanced Parkinsons patients experience on a daily basis, and they dont have to rely on pills while the pump is on, said movement disorders specialist Dr. Mustafa Saad Siddiqui, an associate professor of neurology at Wake Forest Baptist. It can mean a very significant improvement in the quality of life of these patients.
Parkinsons disease is a degenerative disorder of the brain cells that produce dopamine, a chemical that helps people control body movements. While tremors are the best-known sign of Parkinsons, it can also cause muscle rigidity and slowing of movement. There is no cure for the disease, which afflicts approximately 1 million people in the United States, including actor Michael J. Fox and boxing legend Muhammad Ali.

Traditional Treatment Of Parkinsons Disease
The levodopa in pills is absorbed in the blood from the small intestine and travels through the bloodstream to the brain, where it is converted into dopamine and stored in neurons.
In the initial stages of Parkinsons, the brain still has some neurons capable of producing and storing dopamine. The levodopa pills which usually contain a drug called carbidopa to reduce nausea and other side effects give the brain a boost to ensure a sufficient supply of dopamine, thus promoting normal motor control.
But during the diseases more advanced stages, there arent enough neurons left to produce or store enough dopamine. As a result, patients must take more and more levodopa pills in order to supply the brain with adequate levels. At the same time, Parkinsons causes stomach functions to become slow and unpredictable, which can delay or even prevent the medicine in the pills from leaving the stomach and reaching the bloodstream in the small intestine. Consequently, later-stage Parkinsons patients are subject to more frequent and more pronounced motor fluctuations.
Scientists Have Made A Breakthrough In The Development Of A Nasal Spray For Parkinsons Disease Treatment
Researchers from the University of York have developed a new gel that can adhere to tissue inside the nose alongside the drug levodopa, helping deliver Parkinsons disease treatment directly to the brain.
Parkinsons disease is a condition in which parts of the brain become progressively damaged over many years. This leads to a reduction in dopamine in the brain, which plays a vital role in regulating the movement of the body. The main symptoms include involuntary shaking, slow movement, and stiff and inflexible muscles.

Surgery For Parkinsons Disease
Based on the severity of the condition and the medical profile, the doctor may recommend surgery as one treatment option for Parkinson’s disease.
There are several types of surgery that may be performed that can help patients with Parkinson’s disease. Most of the treatments are aimed at helping the tremor or rigidity that comes with the disease. In some patients, surgery may decrease the amount of medication that is needed to control the symptoms.
There are three types of surgeries that may be performed for Parkinson’s disease, including the following:
It is important to remember that surgery may help with symptoms of Parkinson’s disease, but does not cure the disease or stop the progression of the disease.
Advanced And Future Treatments For Parkinsons
While theres no cure for Parkinsons disease, recent research has led to improved treatments.
Scientists and doctors are working together to find a treatment or prevention technique. Research is also seeking to understand who is more likely to develop the disease. In addition, scientists are studying the genetic and environmental factors that increase the chance of a diagnosis.
Here are the latest treatments for this progressive neurological disorder.
In 2002, the FDA approved deep brain stimulation as a treatment for Parkinsons disease. But advances in DBS were limited because only one company was approved to make the device used for the treatment.
In June 2015, the FDA approved the

Studies Show Promising Results
“Considering the ability of MSCs to secrete neurotrophic factors, modulate inflammation, and possibly even act as mitochondria âdonorâ, it comes as no surprise that there is a lot of interest in the use of MSCs in the treatment of Parkinsons Disease, and a multitude of animal studies has shown promise. Treatments have resulted in improvement of motor function, protection of the nigrostriatal system, and improved striatal dopamine release in several studies using toxic lesion rodent models of Parkinsons Disease. Similar effects were reported with umbilical cord-derived MSCs with or without prior differentiation. For example, a recent study reported improvement of motor function, reduced microglial activation, and decreased loss of TH immunoreactivity, associated with local production of trophic factors.

Aptinyx Focuses On Parkinsons Disease Cognitive Impairment
Aptinyx is amid a Phase II trial targeting one of the biggest unmet needs in Parkinson’s disease treatment: cognitive impairment and dementia.
In patients with PD, Lewy bodies and alpha-synuclein, which are implicated in the pathology of PD, can spread into the cortex, causing forms of cognitive impairment and dementia in a large percentage of patients, Kordower explains. Theres no current treatment, so any clinical trial that has some benefit is incredibly valuable, he says.
Aptinyxs NYX-458, which targets the N-methyl-D-aspartate receptor, has placebo-controlled Phase II results expected at the end of 2022 or early 2023. The trial lists eight primary endpoints, ranging from the incidence adverse events to reductions in scales of psychosis and suicidal ideation.
“There’s no current treatment, so any clinical trial that has some benefit is incredibly valuable.”
Jeffrey Kordower
Targeting NMDA is a good start, says Dr David Eidelberg, neurologist at the Feinstein Institutes for Medical Research. However, showing reduction in cognitive impairment may be more difficult in PD than in Alzheimers disease, where changes are typically more pronounced, he notes.
Nevertheless, experts are encouraged that a trial is taking aim at this substantial unmet need. According to GlobalData consensus forecasts, NYX-458 has expected peak sales of $323 million in 2028.

New Medications For Off Time
A number of new medications approved recently are designed to reduce OFF time. These medications fall into two major categories:
- Medications that lengthen the effect of a carbidopa/levodopa dose
- Medications that are used as needed if medication effects wear off
Well give specific examples below. In general, new medications that extend the length of a carbidopa/levodopa dose are used if OFF time is somewhat predictable and occurs prior to next dose. New medications that are used as needed are most beneficial when OFF time is not predictable.
New medications that lengthen the effect of a dose of carbidopa/levodopa
- Istradefylline is an adenosine A2A receptor antagonist which was approved in the US in 2019 as an add-on therapy to levodopa for treatment of OFF time in PD. Unlike many of the other medications, it has a novel mechanism of action and is the first medication in its class to be approved for PD. It acts on the adenosine receptor, which modulates the dopaminergic system, but is not directly dopaminergic. The drug was developed in Japan and underwent clinical trials both in Japan and in the US.
- Opicapone is a catechol-O-methyltransferase inhibitor that is taken once a day. It was approved in the US in 2020 as an add-on therapy to levodopa for motor fluctuations.

Stem Cells For Parkinsons Disease Are Safe And Effective
According the Venkataraman and colleagues, A subjective improvement was found in symptoms like facial expression, gait, and freezing episodes 2 patients have significantly reduced the dosages of PD medicine. These results indicate that our protocol seems to be safe, and no serious adverse events occurred after stem-cell transplantation in PD patients.
As stated in a 2005 study held by Brian Snyder,
Stem cells offer the potential to provide a virtually unlimited supply of optimized dopaminergic neurons that can provide enhanced benefits in comparison to fetal mesencephalic transplants. Stem cells have now been shown to be capable of differentiating into dopamine neurons that provide benefits following transplantation in animal models of Parkinsons disease.

Changes In Cognition And Parkinsons Disease
Some people with Parkinsons may experience changes in their cognitive function, including problems with memory, attention, and the ability to plan and accomplish tasks. Stress, depression, and some medications may also contribute to these changes in cognition.
Over time, as the disease progresses, some people may develop dementia and be diagnosed with Parkinsons dementia, a type of Lewy body dementia. People with Parkinsons dementia may have severe memory and thinking problems that affect daily living.
Talk with your doctor if you or a loved one is diagnosed with Parkinsons disease and is experiencing problems with thinking or memory.
How Could Stem Cells Help People With Parkinson’s
Stem cells are the parent cells of all tissues in the body. This means they can turn into any type of cell. The hope is that they will eventually be able to make these cells into specific types of cells, like dopamine-producing neurons, that can be used to treat Parkinson’s disease. However, there are concerns that patients may have the same risk of increased involuntary movements as those who undergo fetal cell transplantation. And, like fetal cell transplantation, stem cell therapy is surrounded by moral and ethical controversy.

Researchers Are Getting Closer To A Drug That Is Truly A Parkinsons Treatmentone That Can Halt Or Cure The Disease Instead Of Just Fighting Symptoms
As the incidence of Parkinsons growsan estimated 50,000 new cases per yearso do the options being offered by drug manufacturers.
Todays Parkinsons treatment options address the symptoms of tremors, stiffness, and slow movement to improve quality of life. However, they do little to slow the progression of this disease. Fortunately, research is helping us better understand Parkinsons. While early signs of Parkinsons disease can be overlooked, once its diagnosed, treatment options are expanding beyond the current drugs. So one day we may find a Parkinsons treatment that makes the disease less of a life sentence.
If you have Parkinsons disease, there arent any treatments that can slow, reverse, or stop the conditions progression, says Kara J. Wyant, M.D., in a Michigan Health blog on Parkinsons treatment. But, although there is no cure, more than a dozen medications can help patients manage symptoms. Our goals when prescribing medications for Parkinsons disease are twofold: to improve day-to-day functioning and quality of life and to keep people functioning as long as possible.
Scientists Take The Next Step In Unraveling The Relationship The Protein Plays In The Disease
minute read.
An international team of scientists is advancing research in Parkinson’s disease. Today, the team released a new study outlining research that could potentially change the future of treating patients.
Currently, there are no disease-modifying therapies for Parkinsons disease that can change the progression of the disease. An international team of scientists led by faculty at the University of Colorado Anschutz Medical Campus is hoping to change that.
Today, the team published new research in the journal Brain that takes scientists one step closer to understanding -synuclein , a key protein that they found links inflammation and Parkinsons disease.
The protein Syn is predominantly expressed in neurons and is associated with neurodegenerative diseases, such as Parkinsons disease and dementia with Lewy bodies. This new study identifies the novel mechanism that links interferon activation and Syn function in neurons as a potential trigger for developing Parkinsons disease.

What Is The Best Treatment For Parkinson’s Disease
There is no cure for Parkinsons disease, but medications, therapy, and lifestyle changes can improve your symptoms. Medications raise your dopamine levels, change other brain chemical levels, and treat other symptoms like blood pressure, constipation, and trouble sleeping.
Levodopa
Almost everyone with Parkinsons disease will eventually end up taking levodopa, which is an amino acid precursor to dopamine. Your cells absorb the medicine and convert it to dopamine, so it raises your dopamine levels.
Its often used in combination with another drug called carbidopa that slows down dopamine conversion in your blood so that more of it reaches your brain. Carbidopa also stops common side effects of levodopa like nausea and vomiting.
Levodopa also commonly causes a condition called dyskinesia, where you have uncontrollable and jerky movements. Another side effect is called the on-off phenomenon, where you quickly switch between moving and being unable to move.
What Are Mesenchymal Stem Cells
Stem cells are the body’s raw materials â cells from which all other cells with specialized functions are created. Mesenchymal stem cells are adult stem cells that have self-renewal, immunomodulatory, anti-inflammatory, signaling, and differentiation properties. Mesenchymal stem cells , self renewal capacity is characterized by their ability to divide and develop into multiple specialized cell types present in a specific tissue or organ.
Mesenchymal stem cells can be sourced from a variety of tissue including adipose tissue , bone marrow, umbilical cord tissue, blood, liver, dental pulp, and skin.
MSCs are widely used in the treatment of various diseases due to their self-renewable, differentiation, anti-inflammatory, and immunomodulatory properties. In-vitro and in-vivo studies have supported the understanding mechanisms, safety, and efficacy of MSC therapy in clinical applications.
