Peptides with Neurotrophic Properties: Promising Therapeutics for Amyotrophic Lateral Sclerosis and Alzheimer’s Disease.

Peptides with Neurotrophic Properties: Promising Therapeutics for Amyotrophic Lateral Sclerosis and Alzheimer’s Disease.

Alzheimer’s disease (AD) and amyotrophic lateral sclerosis (ALS) are two of the more common neurodegenerative diseases, with nearly seven million people in the US living with the conditions in 2023. While AD is more prevalent than ALS, they are both characterized by the progressive loss of specific neurons and glial cells in the central nervous system.

Research has demonstrated that the onset and progression of neurodegenerative diseases appear to be delayed or improved by the application of neurotrophic factors and that the derived peptide factors from these neurotrophic factors have been found to potentially restore neuronal function, improve behavioral deficits, and prolong their survival.

In this review, Ciesler and Sari review the role of trophic peptides in the improvement of AD and ALS with the goal of developing a better understanding of potential therapies for these neurodegenerative diseases.

While neurodegenerative diseases, including AD and ALS, are well documented to result in debilitating loss of memory and motor function, respectively, the specific mechanisms of action in these diseases are yet to be fully understood. However, research has found that the potential underlying mechanisms can be divided into two categories. The first, which is unique to each neurodegenerative disease, is a specific trigger that activates cell death machinery and the second, which appears to be universal among neurodegenerative diseases, is a directorial process to complete death of a neuron.

While there are currently no effective drugs for the treatment of neurodegenerative diseases, treatments of the symptoms associated with neurodegenerative diseases include neuroprotective factors, encompassing neurotrophins, and neuroprotective peptides. The authors focus this review on NAP peptide derived from activity neuroprotective protein and ADNF-9 peptide derived from activity-dependent neurotrophic factor (ADNF); both of these peptides have been shown to enhance cell survival and outgrowth of dendrites in the form of D-acid analogues.

NAP’s parent protein, ADNP, is essential for brain development and was found to protect neurons against severe oxidative stress. Studies examining NAP have found them to protect against neurotoxins while not affecting cell division.  Considering these findings, NAP is now in phase II clinical trials with a primary focus on AD-related cognitive impairment. Additional studies are also evaluating the effects of NAP in ALS models associated with cytoskeletal dysfunction. NAP has been found to extend life span in ALS mouse models when administered prior to disease onset.

ADNF is released in response to vasoactive intestinal peptide that protects neurons from tetrodotoxin-induced cell death and is suggested to be essential for neuronal survival. ADNF-9 showed greater prevention of cell death associated with stress than other ADNF peptides; additional studies demonstrate that ADNF-9 suppressed SOD-1-mediated cell death. While prolonged survival of ALS mouse model was reported to be marginal, the authors highlight that the study did provide insight into a possible treatment for ALS. 

The authors also highlight colivelin, a hybrid synthetic peptide of ANDF-9 and humanin, which was found to provide neuroprotection against AD-related memory loss and have a more potent neuroprotective effect than humanin and ADNF-9 when they are tested alone against neurotoxicity.

Ciesler and Sari conclude that in contrast to neurotrophic factors these trophic peptides have the ability to cross the blood-brain barrier for efficacy and have potential for future treatment of ALS and AD.

A Comprehensive Review of Mesenchymal Stem Cell Therapy in Amyotrophic Lateral Sclerosis (ALS) Patients

A Comprehensive Review of Mesenchymal Stem Cell Therapy in Amyotrophic Lateral Sclerosis (ALS) Patients

Amyotrophic lateral sclerosis (ALS) is a rare, deadly progressive neurological disease that affects the upper and lower motor neurons. Characterized by weakening and gradual atrophy of the voluntary muscles, ALS gradually affects the ability to eat, speak, move, and eventually breathe.

With an estimated survival rate of 2 to 5 years from disease onset, 90% of ALS patients develop sporadic ALS and there is no known cure. Although the cause of ALS remains unknown, there is scientific evidence that both genetics and environment are key contributors. This evidence includes over 30 different gene mutations and a number of environmental factors (exposure to toxins, heavy metals, pesticides, smoking, and diet) have been found to be associated with neurological destruction and ALS development. Additionally, ALS has been found to be approximately 2 times more likely to occur in men than women. 

In the search for a definitive cure for ALS, the use of mesenchymal stem cells (MSCs) for both treatment and management of the condition has been increasingly more common in preclinical and clinical studies. 

In this review, Najafi et al. discuss multiple aspects of ALS and focus on MSCs’ role in disease management as demonstrated in clinical trials. 

MSCs are multipotent cells with immunoregulatory, anti-inflammatory, and differentiation abilities that make them a strong candidate for use in therapeutic applications intending to expand the lifespan of ALS patients. 

To date, preclinical research investigating the cause and potential treatment of ALS primarily relies on data gathered from rat and mouse models. As part of these models, researchers have discovered that the transplantation of MSCs through multiple routes (including intrathecal, intravenous, intramuscular, and intracerebral) can be a safe and effective way to delay the decline of motor function and promote neurogenesis.  

These preclinical studies have also demonstrated that the administration of MSCs from specific tissues has shown significant advantages in delaying the degeneration of motor neurons, improving motor function, and extending lifespan.

Over 20 years of clinical research have found that direct injection of autologous expanded MSCs is safe and well tolerated and demonstrated a significant decrease in disease progression and increase in life expectancy in patients. 

The authors conclude that ALS is a fatal neurodegenerative disease with no definitive cure.  However, several preclinical and clinical studies have shown that MSC’s anti-inflammatory, immunoregulator, and differentiation properties, have demonstrated to be a good therapeutic approach for treating ALS.

The Safety and Efficacy of Stem Cell Therapy For ALS

The Safety and Efficacy of Stem Cell Therapy For ALS

As science continues to uncover the benefits of stem cell therapy, many trials and studies are bringing their focus to conditions with limited treatment options. The neurodegenerative condition amyotrophic lateral sclerosis (ALS) is one of the conditions that greatly needs new treatment methods to slow its progression. Fortunately, recent clinical trials offer promising results. Here we will discuss Stem cell therapy for ALS.

What Is ALS?

ALS affects the nerve cells present in the brain and spinal cord. In ALS patients, the motor neurons that carry messages from the brain to the spinal cord and then to the body’s muscles progressively die off. As they die, the brain can no longer communicate with the muscles, so patients lose muscle action. 

The loss of muscle control may begin with walking and standing, but patients can lose the ability to move, speak, eat, and breathe over time. 

How Can Stem Cell Therapy Help ALS Patients?

Stem cells are the building blocks of cells. When prompted to divide, stem cells can either form more stem cells or become specialized cells, such as brain cells or nerve cells. Those new, specialized cells have the potential to repair and replace damaged cells. 

Stem cell therapy is an inspiring option in treating ALS since researchers believe the treatment could support new cell growth and help manage the body’s immune system response. Additionally, stem cells offer the potential to regenerate the damaged motor neurons that are characteristic of the disease. 

Clinical Trial Results

In an analysis of six clinical trials that examined the benefits of stem cell treatments in slowing the progression of ALS, all six trials showed stem cell therapy slowed the advancement of the disease. However, in two studies, the results were not statistically significant. 

All of the studies that followed patients for six months after their stem cell treatments saw significant differences in the results of patients’ ALSFRS-R reports. Patients within the treatment groups experienced a notable slowing in the disease’s progression. In examining the methodologies of the studies analyzed, there are techniques and types of stem cells that show improved results. Notably, the most effective delivery of stem cells to slow ALS in patients is through injections into the fluid-filled space surrounding the spinal cord. In addition, studies using mesenchymal stem cells (MSCs) also saw more significant results than other stem cell therapies.

What Are The Symptoms of ALS?

What Are The Symptoms of ALS?

Amyotrophic lateral sclerosis (ALS) is a progressive disease of the nervous system that targets the nerve cells in the brain and the spinal cord. Also known as Lou Gehrig’s disease, the condition eventually causes patients to lose muscle control. While ALS currently has no cure, early identification allows patients to use various therapies to delay the advancement of symptoms. Here we will answer a very common question ” what are the symptoms of ALS? “. Keep reading to learn more!

Early ALS Symptoms

Since ALS is a progressive disease, symptoms appear gradually, and patients often ignore early signs. The progression of ALS differs in each patient, as it can target varying neurons. However, there are some common early symptoms, including:

  • Slurred speech
  • Trouble gripping items with hands
  • Issues swallowing
  • Stumbling
  • Muscle cramps
  • Poor posture
  • Trouble holding up your head
  • Muscle stiffness

ALS symptoms typically begin in the extremities and the limbs before spreading through the body. Both early and later stages of ALS have no pain. 

Advanced ALS Symptoms

As ALS spreads through the body, symptoms worsen. These symptoms include:

  • Less muscle mass
  • Struggles with chewing and swallowing
  • Weaker muscles
  • Poor or slurred speech
  • Trouble breathing

Later stages of ALS affect more of the patient’s muscles and movement. 

What Causes ALS?

While the exact cause of ALS is unknown, about 5–10% of ALS patients inherit a familial ALS form. Children of familial ALS patients have a 50/50 chance of developing the disease. 

Most scientific theories on the cause center on a complex interaction between environmental and genetic factors for those with ALS and no familial connection. Smoking, environmental toxin exposure, and military service all appear to contribute to the development of the disease, although researchers aren’t entirely sure how or why.

How Can Patients Manage ALS Symptoms?

During the early stages of ALS, patients benefit from various therapies to delay the progression of symptoms. Physical therapy, occupational therapy, and speech therapy help patients improve their quality of life as the disease progresses.

Physical Therapy

Physical therapy can extend the amount of time a patient can walk unassisted. Physical therapists work with patients to retain strength in their larger muscle groups and to maintain balance and gross motor skills. 

Occupational Therapy

Occupational therapy focuses more on smaller muscle movements, such as using eating utensils, brushing teeth, and getting dressed. Occupational therapists may also work with patients to find alternative methods for completing tasks as specific muscles weaken.

Speech Therapy

Speech therapy assists ALS patients in retaining their clarity of speech and swallowing and chewing as the tongue begins to weaken.

While early ALS symptoms, such as an occasional muscle cramp or feeling of weakness, are no cause for concern, if you’re noticing weakness in your hands or feet for days, it’s worth seeing a physician. Some early symptoms of ALS may also be symptoms of other, less-serious health concerns.Many patients are exploring the alternative option of stem cell therapy. This regenerative medicine therapy can help manage symptoms and help slow the progression of the condition. Mesenchymal stem cells may offer a potential benefit in how they target damaged tissues, help in neuronal and non-neuronal cell replacement, trophic factor delivery, and modulation of the immune system.

Stem Cell Therapy For Amyotrophic Lateral Sclerosis

Stem Cell Therapy For Amyotrophic Lateral Sclerosis

Standard treatment protocols for Amyotrophic Lateral Sclerosis (ALS) are typically focused on educating and managing the severity of symptoms they may be facing. However, stem cell-based therapy is an alternative option for managing this condition and its symptoms. This optional therapy has been the subject of several studies in recent years and the initial results have shown positive outcomes. Here we will talk about Stem cell therapy for Amyotrophic Lateral Sclerosis.

Regenerative medicine, also known as stem cell therapy, involves the administration of a concentrated volume of stem cells to targeted areas. It is a management tool to potentially slow down the progression of ALS as well as help to manage symptoms or the development of new symptoms. 

Stem cells are naturally present in the body. Mesenchymal stem cells are the most commonly used in cell-based therapies. They can be derived from autologous (Adipose or Bone Marrow) and allogeneic tissues (Wharton’s Jelly). Studies have shown these to be safe and potentially effective for their regenerative and therapeutic properties. 

Below, we’ll examine the potential benefits of cell-based therapies for ALS.

The Condition

Often referred to as Lou Gehrig’s disease, Amyotrophic Lateral Sclerosis is a neurodegenerative condition that is characterized by a progressive breakdown in motor skills and voluntary control of movements. The condition can progress quickly or slowly over time.

Some of the most common symptoms of ALS include:

  • Difficulty walking
  • Frequent falling and tripping
  • Weakness in the hands
  • Slurred speech
  • Muscle cramps
  • Inappropriate laughing or crying
  • Behavioral and cognitive changes

Potential Application of Stem Cells for Managing ALS

Currently, the potential benefits of stem cell therapy for ALS are still being researched and studied. With that being said, early data is has shown to be promising. 

Patients who have had little success with conventional protocols or may want to add to their current therapies have been exploring stem cell therapy to potentially slow the progression of the disease and help manage symptoms. Mesenchymal stem cells help stimulate the body’s natural healing capabilities and have the ability to regenerate damaged tissues. 

A clinical trial showed results that support that stem cells could potentially reduce functional impairments. Patients in the trial experienced no significant side effects and the procedure was tolerated well by all of the trial participants. 

Stem cells are safe for repetitive use, as well, which means that patients can receive ongoing maintenance treatments if the therapy provides positive results even if this result is slowing down or stabilizing the progression of the condition.

The hope is that there will soon be additional, large-scale randomized control trials on stem cell therapies for ALS in the future. These types of trials would provide further insights into the potential of this treatment option for ALS patients. 

Fortunately, access to stem cell therapy for Amyotrophic Lateral Sclerosis ( ALS ) is currently available, which gives patients additional therapy options when exploring how to help manage their condition and symptoms.

Stem Cell Treatment for Lou Gehrig’s Disease (ALS)

Stem Cell Treatment for Lou Gehrig’s Disease (ALS)

For those who are suffering from Lou Gehrig’s Disease — now commonly referred to as Amyotrophic Lateral Sclerosis (ALS) — finding treatment for the condition can seem like a never-ending quest. Stem cells have been used for several years to treat a wide variety of diseases, and many of these treatments point to the potential for further exploration. 

Some of the beneficiaries of this process are ALS sufferers. Although there is no cure for ALS, stem cell therapy offers the chance to slow the progression of the disease while also helping to control its symptoms. While there are currently drug treatments available to address the disease, they all have side effects and may offer only limited means of controlling ALS.

In contrast, regenerative medicine, also known as stem cell therapy, offers a new avenue for pursuing ALS treatment, one that shows promising potential for improving patient outcomes over the long term. Regenerative medicine provides patients another path to managing their condition, one that may provide improved symptoms and potential long-term benefits.

What are Stem Cells?

The primary cells used for ALS-related stem cell therapy are called mesenchymal stem cells. These cells are derived from adipose (fat) or umbilical cord (Wharton’s Jelly) cells, and they have a unique ability to differentiate themselves into a wide variety of tissues. 

Once inserted into the human body, the goal is to have them protect against cell loss by regrowing nerve cells and pathways in the brain.

Stem cell procedures like the ones used for treating ALS are generally considered to be safe, as patients rarely suffer from complications or side effects. In a study published in Neurology, for example, patients treated with mesenchymal cells did not show a markedly elevated risk for complications. 

Expected Outcomes

While stem cells for ALS patients should not be seen as a potential cure, many patients have reported improvement in some areas, including:

  • Repairs in nerve damage
  • Reduced progression of the disease
  • Motor skill improvements
  • Higher energy levels

While these results can’t be guaranteed for all patients, they represent major steps forward for those who have not had success with traditional treatments or those who need more help in dealing with progressively worse symptoms of ALS.

Like many treatments for ALS, stem cell therapy is considered to be experimental, which means that it does not have approval from the FDA. However, regenerative medicine may offer a window to an improved patient experience by easing symptoms of the disease that would otherwise be debilitating.
