Summary: A new research has shown that troriluzole may prevent early-stage mental changes in a mouse model of Alzheimer’s disease. Troriluzole, in accordance with the research, lowers dangerous serotonin levels while maintaining memory and cognitive function.
This discovery gives rise to new hope for possible treatments because it suggests that early treatment with troriluzole had slow or even stop Alzheimer’s progression. However, more studies are required to compare its performance across various disease stages.
Important Facts:
- Troriluzole reduces dangerous serotonin levels, protecting mental performance.
- Mice given troriluzole had better memory and learning capabilities.
- More research is needed to discover troriluzole’s effects across all stages of Alzheimer’s.

In a recent development in Alzheimer’s disease studies, Auburn University researchers have studied a new medication, troriluzole, that may prevent mental modifications leading to memory loss and cognitive decline in a mouse model of the condition.
This research, recently published in the , Journal of Neurochemistry, is the first to demonstrate how troriluzole you target early-stage abnormalities associated with Alzheimer’s, providing new promise for possible treatments.
Dr. Miranda Reed, a teacher in Auburn University’s department of medicine identification and the lead researcher on the study, stated that” by looking at how medicine treatments can intervene early in the disease process, we aim to develop therapies that may reduce or even cure Alzheimer’s.”  ,
” This study also highlights how scientific advancements can transform our understanding of complex diseases like Alzheimer’s”, said Dr. Michael Gramlich, an Assistant Professor of Biophysics and the study’s other main researcher.
Breaking New Ground in Alzheimer’s Research
Alzheimer’s disease affects millions of people worldwide, causing progressive memory loss, confusion, and eventually the inability to perform basic tasks. Despite decades of research, a cure remains elusive. Alzheimer’s is characterized by the accumulation of amyloid plaques and tau tangles in the brain, which disrupt neural communication. Overuse of the neurotransmitter glutamate in the early stages leads to damaging synapses, or nerve cell connections, overactivity.
The study conducted by Auburn University researchers, led by Drs. Miranda Reed and Michael Gramlich, investigated how troriluzole, a novel drug, can maintain normal brain function in mice genetically modified to replicate early Alzheimer’s stages. The outcomes are conclusive: troriluzole improved memory and learning in the mice, suggesting a maintenance of healthy brain function. Not only did it lower harmful glutamate levels.
Our research suggests that by focusing on synaptic activity early, we might be able to stop or slow the progression of Alzheimer’s. This could revolutionize the way we approach treatment for this disease”, noted both researchers.
How Troriluzole Works
In the Auburn study, mice treated with troriluzole showed a marked decrease in brain hyperactivity and synaptic glutamate levels. These molecular changes produced tangible improvements: the treated mice performed better on memory tests like navigating mazes, which suggests that their cognitive functions were restored.
These findings are encouraging because they demonstrate that troriluzole can protect the brain at a fundamental level, starting with molecular changes, and improving cognitive abilities, according to Dr. Reed. ” It’s like repairing an engine before it fails completely”.
A Collaborative Effort with Wide Implications
This research was a collaborative effort involving Auburn University’s College of Science and Mathematics, the Harrison College of Pharmacy, and the Center for Neuroscience Initiative, along with private researchers and students. The team’s combined knowledge of neuroscience and pharmacology was essential to the success of the study.
Dr. Gramlich praised the collaboration between basic science and pharmaceutical research to address one of the most pressing neurological issues of our time. Our research advances the understanding of Alzheimer’s disease in the scientific community as well as suggests a potential new treatment that could improve the lives of millions of people worldwide.
What’s Next?
The researchers emphasize the need for further studies to understand how troriluzole functions at various stages of disease progression, despite the results from mice.

” Troriluzole rescues glutamatergic deficits, amyloid and tau pathology, and synaptic and memory impairments in 3xTg-AD mice” by Michael Gramlich et al. Journal of Neurochemistry
Abstract
Troriluzole rescues glutamatergic deficits, amyloid and tau pathology, and synaptic and memory impairments in 3xTg-AD mice
In a neurodegenerative condition called Alzheimer’s disease ( AD), clinical symptoms are closely related to the loss of glutamatergic synapses. In the early stages, pathological accumulation of glutamate and hyperactivity contribute to AD pathology and cognitive dysfunction, while later stages of AD are associated with markedly decreased glutamate levels due to neuronal loss.
There is increasing awareness that presynaptic dysfunction, particularly synaptic vesicle ( SV ) alterations, play a key role in mediating this early-stage hyperactivity.
In the current study, we sought to find out whether the 3xTg mouse model of AD, which exhibits both beta-amyloid ( A ) and tau-related pathology, would have the same presynaptic changes as those that have previously been observed in the amyloid or tau models separately.
Utilizing hippocampal cultures from 3xTg mice to test whether postsynaptic activity is controlled by the vesicular glutamate transporters (VGlut ) and glutamate at the synaptic level.
Similar to previous observations in cultures made using tau mouse models, we found that 3xTg hippocampal cultures had higher VGlut1 levels and a higher glutamate release.
However, 3xTg cultures also had a larger SV pool, an occurrence that was not previously seen in tau mouse models but also in ATM cultures, suggesting that the pool size changes may be attributable to A rather than tau.
Second, we sought to determine whether treatment with troriluzole, a novel 3rd generation tripeptide prodrug of the glutamate modulator riluzole, could reduce VGlut1 and glutamate release to restore cognitive deficits in 8-month-old 3xTg mice.
Treatment with troriluzole reduced VGlut1 expression, decreased basal and evoked glutamate release, and restored cognitive deficits in 3xTg mice.
Together, these findings suggest presynaptic alterations are early events in AD that represent potential targets for therapeutic intervention, and these results support the promise of glutamate-modulating drugs such as troriluzole in Alzheimer’s disease.
