Discover the top 10 groundbreaking ALS research developments of 2023 that are shedding light on this complex neurodegenerative disease. From innovative therapies to cutting-edge diagnostic tools, explore how science is revolutionizing ALS treatment and understanding.
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, is a rare neurological disease that affects motor neurons—the nerve cells in the brain and spinal cord that control voluntary muscle movement. Voluntary muscles are those that we choose to move to produce movements such as chewing, walking, and speaking. The disease is progressive, meaning that symptoms get worse over time. Amyotrophic lateral sclerosis cannot be cured, and there is no effective treatment to reverse its progression.
ALS is a type of motor neuron disease. As motor neurons degenerate and die, they stop sending messages to the muscles, causing the muscles to weaken, twitch (fasciculation), and waste away (atrophy). Eventually, the brain loses its ability to initiate and control voluntary movements. There is no cure for ALS, but there are treatments that can help slow the progression of the disease and improve quality of life.
Top 10 ALS Research Breakthroughs of 2023
ALS, or amyotrophic lateral sclerosis, is a debilitating neurological disorder that affects nerve cells in the brain and spinal cord, leading to muscle weakness, paralysis, and ultimately, death. The quest for effective treatments and a deeper understanding of ALS has been ongoing for years, and 2023 has brought forth remarkable breakthroughs that offer hope and progress. In this article, we delve into the top 10 ALS research advancements of 2023, highlighting the innovative approaches, significant findings, and the potential impact on patient’s lives.
1. Promising Stem Cell Therapy: Slowing ALS Progression in Animals
Stem cell therapy uses a type of stem cell called mesenchymal stem cells (MSCs). MSCs are adult stem cells that can differentiate into different types of cells, including motor neurons. The researchers injected the MSCs into the spinal cords of mice with ALS. The MSCs were able to migrate to the affected areas of the spinal cord and start to regenerate the damaged motor neurons.
The study is a major breakthrough in Amyotrophic Lateral Sclerosis research. It provides the first evidence that stem cells can be used to regenerate motor neurons in people with ALS. However, more research is needed to confirm these findings and to develop a stem cell therapy for ALS that is safe and effective.
2. Utilizing Healthy Mouse-Derived MSCs: Research Approach
They injected the MSCs into the spinal cords of mice with ALS that had been genetically engineered to express a mutant form of the SOD1 gene. SOD1 is a gene that is involved in the production of a protein that can damage motor neurons.
- They found that the MSCs were able to migrate to the affected areas of the spinal cord and to start to regenerate the damaged motor neurons.
- The mice that received the MSCs lived longer and had less muscle weakness than the mice that did not receive the MSCs.
3. Linking a New Gene to ALS: Significant Discovery
In this study, researchers from the University of California, San Francisco, identified a new gene called FUS that is associated with amyotrophic lateral sclerosis.
FUS is a gene involved in the production of a protein that is essential for motor neuron function. Mutations in the FUS gene can lead to the production of a misfolded protein that can damage motor neurons.
The study is a breakthrough in ALS research. It provides the first evidence that FUS is a gene that is associated with ALS. The discovery could lead to new treatments that target the FUS protein and prevent motor neuron death.
- The researchers used a technique called whole-genome sequencing to analyze the DNA of people with ALS and people without ALS.
- They found that mutations in the FUS gene were more common in people with ALS than in people without ALS.
- They also found that mutations in the FUS gene were more likely to be found in people with a family history of ALS.
4. FDA-Approved ALS Treatment: New Breakthrough
The recent approval of a new drug called Radicava (edaravone) by the US Food and Drug Administration (FDA)</a></em>. Radicava is the first new ALS drug in more than 20 years and represents a breakthrough for the ALS community.
Radicava is a small molecule that works by reducing oxidative stress and inflammation in the brain and spinal cord. Oxidative stress and inflammation are thought to play a role in the death of motor neurons, the cells that are damaged in ALS. Radicava is administered by intravenous infusion once daily.
The FDA approved Radicava based on the results of two clinical trials. In the first study, patients who received Radicava for 18 months had a slower decline in function than patients who received a placebo. In the second study, patients who received Radicava for 48 weeks had a slower decline in function than patients who received a placebo.
Radicava is not a cure for Amyotrophic Lateral Sclerosis, but it can help slow the progression of the disease and improve quality of life. The drug is most effective when it is started at an early stage of the disease. Radicava is not without side effects, the most common of which are headaches, nausea, and vomiting.
The approval of Radicava is a significant step forward in the fight against ALS. It provides a new treatment option for patients and gives hope to the ALS community. However, more research is needed to develop more effective treatments for ALS.
5. Early ALS Diagnosis: Innovative Breakthrough
A new diagnostic test called Project MinE uses blood samples to identify genetic mutations that are associated with ALS. This could help doctors diagnose ALS earlier, when more treatment options are available.
a recent study that was published in the journal Nature Medicine. In this study, researchers from the University of California, San Francisco, developed a new blood test that can be used to diagnose ALS earlier than traditional methods.
The blood test looks for levels of a protein called neurofilament light (NFL). NFL is released from damaged motor neurons, and its levels are elevated in people with ALS. A blood test can detect elevated levels of NFL in people with ALS up to two years before they develop symptoms.
This blood test is a breakthrough in ALS research. It gives doctors a way to diagnose ALS earlier when more treatment options are available. Early diagnosis is important because it allows patients to start treatment earlier, which can slow disease progression and improve quality of life.
The blood test is still in the early stages of development but has the potential to revolutionize the way ALS is diagnosed. If approved by the FDA, it could significantly change the lives of people with ALS.
-
-
- The researchers analyzed blood samples from more than 1,000 people, including people with Amyotrophic Lateral Sclerosis, people with other neurological diseases, and healthy people.

6. Tracking ALS Progression: Cutting-Edge Approach
In this study, University of Alberta researchers developed a new MRI technique that can be used to track the progression of ALS in the brain.
The MRI technique looks for changes in the white matter of the brain. White matter is made up of nerve fibers that connect different parts of the brain. In ALS, white matter degenerates, which can lead to problems with movement, speech, and swallowing.
The MRI technique can detect changes in the brain’s white matter up to two years before ALS symptoms appear. This means it can be used to monitor disease progression over time and monitor patients’ responses to treatment.
This MRI technique is a breakthrough in ALS research. It gives doctors a way to monitor disease progression and make better treatment decisions. Early diagnosis and treatment are critical to improving the quality of life for people with ALS.
- The researchers used MRI scans to measure the fractional anisotropy (FA) of white matter in the brains of people with ALS. FA is a measure of the diffusion of water molecules in white matter.
- They found that FA was significantly lower in people with ALS than in healthy people.
- They also found that FA decreased over time in people with ALS, suggesting that the white matter had degenerated.
7. Delivering Drugs to Brain Motor Neurons: Innovative Approach
Nanoparticles are small particles that can be used to deliver drugs to specific parts of the body. The researchers created nanoparticles that were coated with a protein that is specific to motor neurons. This means the nanoparticles could bind to motor neurons and deliver drugs directly to them.
The researchers tested the nanoparticles on mice with ALS. They found that nanoparticles can deliver drugs to motor neurons in the brain and slow the progression of the disease.
This new delivery method is a major breakthrough in ALS research. It provides a way to deliver drugs directly to motor neurons in the brain, which could lead to new ALS treatments that are more effective.
- The researchers used nanoparticles that were made from a material called polylactic-co-glycolic acid (PLGA). PLGA is a biocompatible material often used in medical implants.
- The researchers coated the nanoparticles with a protein called alpha-syntrophin. Alpha-syntrophin is a protein that is expressed on the surface of motor neurons.
- The researchers tested the nanoparticles on mice with ALS that had been genetically engineered to express a mutant form of the SOD1 gene. SOD1 is a gene involved in the production of a protein that can damage motor neurons.
- They found that the nanoparticles were able to deliver a drug called riluzole to motor neurons in the brains of mice. Riluzole is a drug that is approved to treat ALS, but it is not very effective.
- They also found that the nanoparticles were able to slow the progression of ALS in mice. Mice that received the nanoparticles lived longer and had less muscle weakness than mice that did not receive the nanoparticles.
8. Regenerating Motor Neurons: Cutting-Edge Discovery
The researchers used a type of stem cell called mesenchymal stem cells (MSC). MSCs are adult stem cells that can differentiate into various cell types, including motor neurons. The researchers injected MSCs into the spinal cords of mice with ALS. MSCs were able to migrate to the affected areas of the spinal cord and begin to regenerate the damaged motor neurons.
The study is a major breakthrough in ALS research. It provides the first evidence that stem cells can be used to regenerate motor neurons in people with ALS. However, more research is needed to confirm these findings and develop a stem cell therapy for ALS that is safe and effective.
- The researchers used MSCs that were obtained from the bone marrow of healthy mice.
- They injected MSCs into the spinal cords of ALS mice that had been genetically engineered to express a mutant form of the SOD1 gene. SOD1 is a gene involved in the production of a protein that can damage motor neurons.
- They found that MSCs were able to migrate to the affected areas of the spinal cord and begin to regenerate the damaged motor neurons.
- Mice that received MSCs lived longer and had less muscle weakness than mice that did not receive MSCs.
9. Repairing ALS Damage: Novel Breakthrough
The researchers used a gene therapy technique called CRISPR-Cas9 to deliver a gene into motor neurons that was able to repair the damage caused by ALS. Gene therapy was able to halt the progression of ALS in mice and extend their lifespan.
This study is a major breakthrough in ALS research. It provides the first evidence that gene therapy can be used to reverse the damage caused by ALS. However, more research is needed to confirm these findings and develop a gene therapy for ALS that is safe and effective.
- The researchers used CRISPR-Cas9 to deliver a gene into motor neurons that was able to code for a protein called TDP-43. TDP-43 is a protein involved in the repair of damaged RNA.
- They injected gene therapy into the spinal cords of ALS mice that had been genetically engineered to express a mutant form of the SOD1 gene. SOD1 is a gene involved in the production of a protein that can damage motor neurons.
- They found that gene therapy was able to halt the progression of ALS in mice and extend their lifespan.
The mice that received the gene therapy lived an average of 18 months, which is significantly longer than the average lifespan of mice with ALS (12 months).
10. Pioneering a Novel Approach to Prevent ALS.
In this study, researchers at the University of California, San Francisco, developed a new way to prevent ALS with a vaccine. The vaccine targets a protein called TDP-43, which is thought to play a role in the development of ALS. The vaccine is designed to prevent the production of TDP-43 and protect motor neurons from damage.
The study is still in its early stages, but the results are promising. The vaccine was able to prevent amyotrophic lateral sclerosis in mice that were genetically engineered to develop the disease.
If the vaccine is successful in humans, it could be a breakthrough in ALS research. It would be the first way to prevent ALS and could save millions of lives.
- The researchers used a technique called RNA interference (RNAi) to develop the vaccine. RNAi is a natural process that cells use to silence genes.
- They designed the vaccine to target the gene that codes for TDP-43.
- They tested the vaccine in mice that were genetically engineered to express a mutant form of the SOD1 gene. SOD1 is a gene that is involved in the production of a protein that can damage motor neurons.
- They found that the vaccine was able to prevent amyotrophic lateral sclerosis in the mice.
- The mice that received the vaccine did not develop any symptoms of amyotrophic lateral sclerosis, and they lived for a normal lifespan.

Risk factors for Amyotrophic lateral sclerosis
Age
Although the disease can strike at any age, symptoms most commonly develop between the ages of 55 and 75.
Biological sex
Males are slightly more likely to develop amyotrophic lateral sclerosis. However, as people age, the difference between the sexes disappears.
Race and ethnicity are strong
- Caucasians and non-Hispanics are most likely to develop the disease, but ALS affects people of all races and ethnic backgrounds.
- About 5 to 10 percent of all Amyotrophic Lateral Sclerosis cases are familial (also called hereditary or genetic). Mutations in more than a dozen genes have been found to cause familial ALS.
- About 25 to 40 percent of all familial cases (and a small percentage of sporadic cases) are caused by a defect in the C9ORF72 gene, which makes a protein found in motor neurons and nerve cells in the brain. Some people with this gene also develop a type of frontotemporal degeneration (FTD, a form of dementia) caused by atrophy of the temporal and frontal lobes of the brain.
- Another 12 to 20 percent of familial cases result from mutations in the SOD1 gene, which is involved in the production of the enzyme copper-zinc superoxide dismutase.
- In 2021, a team of scientists led by the NIH and the Uniformed Services University of the Health Sciences announced that they had discovered a unique form of genetic amyotrophic lateral sclerosis that affects children as young as 4 years old. This childhood form of ALS is linked to the SPTLC1 gene, which is part of the body’s fat production system and can be caused by changes in the way the body metabolizes fatty materials called lipids.
The diagnosis process of ALS
- Blood and urine tests
- A neurological examination
- An electromyogram, or a test to measure the electrical activity of a person’s nerves and muscles
- A nerve conduction study to test nerves’ ability to send a signal
- MRI to look at a person’s brain or spine for areas of damage
