Researchers tested a natural substance called syringic acid to see if it could help with schizophrenia symptoms in mice. They created schizophrenia-like symptoms in mice and then gave some of them syringic acid. The mice that received the treatment showed improvement in behavior and brain health. The compound appeared to reduce brain inflammation and help repair protective coating around nerve cells. While these results are encouraging, this is early-stage research in animals, and much more testing would be needed before this could help people with schizophrenia.

The Quick Take

  • What they studied: Whether a natural plant compound called syringic acid could reduce schizophrenia-like symptoms and brain damage in mice
  • Who participated: Male mice divided into four groups: healthy mice, mice with induced schizophrenia symptoms, and two groups of sick mice treated with different doses of syringic acid
  • Key finding: Mice treated with syringic acid showed significant improvement in behavior and brain health compared to untreated mice with schizophrenia symptoms. The treatment reduced brain inflammation and helped restore protective coating on nerve cells.
  • What it means for you: This is very early research in animals only. It suggests syringic acid might be worth studying further for schizophrenia, but it’s far too soon to say whether it would help people. Anyone with schizophrenia should continue their current medical treatment and discuss any new treatments with their doctor.

The Research Details

Scientists created schizophrenia-like symptoms in mice by feeding them a special diet containing a chemical called cuprizone for 6 weeks. This chemical damages the brain in ways similar to what happens in human schizophrenia. The mice were then divided into groups: one group stayed healthy as a comparison, one group had the brain damage but no treatment, and two groups received different amounts of syringic acid (a natural compound found in plants) while having the brain damage.

The researchers measured many things in the mice’s brains and behavior. They looked at how the mice acted, checked brain tissue under a microscope, and measured levels of different proteins and chemicals in the brain that are related to inflammation and nerve cell health.

This type of study is called a preclinical study because it happens in animals before any human testing. It helps scientists understand if a treatment might be worth testing in people someday.

Understanding what causes schizophrenia in the brain is crucial for developing new treatments. This study focused on two problems that scientists believe contribute to schizophrenia: inflammation in the brain and damage to myelin (the protective coating around nerve cells). By testing a natural compound that might fix both problems, researchers can learn whether this approach is worth pursuing further.

This study was well-designed with control groups for comparison, which is important for reliable results. The researchers measured multiple markers of brain health, which provides a more complete picture than measuring just one thing. However, this is animal research, so results may not translate directly to humans. The study size appears modest, and the findings would need to be confirmed by other research teams before drawing firm conclusions.

What the Results Show

Mice that received syringic acid showed significant improvement in behavior compared to mice with schizophrenia symptoms that didn’t receive treatment. The treated mice moved around more normally and showed fewer signs of the behavioral problems that the brain damage had caused.

In the brain tissue, syringic acid treatment increased levels of myelin basic protein (MBP), which is the main component of the protective coating around nerve cells. This suggests the treatment helped repair damage to this crucial brain structure. The compound also increased levels of several protective proteins that help nerve cells survive and communicate properly.

At the same time, syringic acid reduced markers of brain inflammation. Specifically, it lowered levels of galectin-3 and TNF-alpha, which are chemicals that indicate inflammation is happening in the brain. The treatment also reduced activation of brain cells called glia, which can contribute to inflammation when overactive.

When researchers looked at brain tissue under a microscope, they could see that the structural damage caused by the chemical was less severe in mice that received syringic acid compared to untreated mice.

The study found that syringic acid worked through specific molecular pathways in the brain. It activated a pathway called PI3K/AKT1 that helps protect nerve cells and promote their survival. The compound also reduced activity of GSK3-beta, a protein that can be overactive in schizophrenia and contribute to nerve cell damage. Additionally, syringic acid increased levels of neuregulin-1 and protein kinase C, both of which are important for maintaining healthy myelin and nerve cell function.

Previous research has suggested that both brain inflammation and myelin damage play roles in schizophrenia. This study is notable because it tested a single compound that appears to address both problems simultaneously. Most existing schizophrenia medications primarily affect dopamine, a brain chemical involved in symptoms like hallucinations and delusions. This research suggests a different approach—reducing inflammation and repairing nerve cell coating—might also be beneficial. The findings align with growing scientific interest in anti-inflammatory approaches to psychiatric disorders.

This research was conducted only in mice, not humans, so results may not apply to people with schizophrenia. The study used a chemical method to create schizophrenia-like symptoms, which may not perfectly replicate the human disease. The sample size appears relatively small, which means results should be confirmed in larger studies. The study didn’t compare syringic acid to existing schizophrenia medications, so we don’t know how it would compare in effectiveness. Additionally, this was a short-term study, so we don’t know about long-term effects or safety. Finally, the study was conducted in male mice only, so results may differ in females.

The Bottom Line

This research is too early-stage to make any recommendations for human use. It’s a promising initial finding that suggests syringic acid deserves further study, but many steps of testing would be needed before it could be considered for people. Current evidence level: Very preliminary (animal study only). Anyone with schizophrenia should continue their prescribed medications and work with their healthcare provider before considering any new treatments.

This research is most relevant to neuroscientists and psychiatrists studying new approaches to schizophrenia. People with schizophrenia or their families might find it interesting as a sign of future research directions, but should not expect this to be available as a treatment anytime soon. Researchers studying inflammation in brain disorders may also find this work relevant.

If this research leads to human testing, it would typically take many years. First, more animal studies would be needed to confirm safety and effectiveness. Then, if approved, human trials would start with small groups to test safety, followed by larger trials to test effectiveness. This process typically takes 5-10 years or longer before a new treatment could become available to patients.

Want to Apply This Research?

  • Users interested in schizophrenia research could track their awareness of emerging treatments by setting reminders to review new research summaries monthly. They could also track mood and behavioral symptoms if working with a healthcare provider, noting any changes as new treatments are discussed.
  • While this specific compound isn’t yet available, users could use the app to track adherence to current schizophrenia medications and behavioral strategies. They could also set reminders to discuss new research findings with their psychiatrist during regular appointments, staying informed about emerging treatment options.
  • Create a research tracking feature where users can save and monitor emerging treatments for schizophrenia. Users could set notifications for when new research is published in this area and maintain a discussion list of topics to bring up with their healthcare provider at future appointments.

This research is preliminary animal-based science and should not be considered a treatment recommendation for schizophrenia. Syringic acid is not currently approved for treating schizophrenia in humans. People with schizophrenia should continue their prescribed medications and consult with their psychiatrist or healthcare provider before making any changes to their treatment plan.
