Porto, Portugal – A groundbreaking study conducted at the Institute of research and Innovation in Health at the university of Porto (i3S) is providing fresh insights and potential therapeutic strategies for Hereditary Transthyretin Amyloidosis, commonly known as foot disease. The research, published in the peer-reviewed journal Cell Reports, points to a novel approach focusing on restoring neuronal health.
Understanding Hereditary Transthyretin amyloidosis
Hereditary Transthyretin Amyloidosis is a rare,inherited condition caused by mutations in the TTR gene. This gene is responsible for producing transthyretin,a protein vital for transporting vitamin A and thyroid hormone throughout the body. When the protein misfolds and accumulates, particularly in the peripheral nerves, it leads to nerve damage, causing symptoms like loss of sensation and muscle weakness, affecting mobility and quality of life.
According to the National Organization for rare Disorders (NORD), an estimated 10,000 individuals worldwide are affected by this disease, with a disproportionately high prevalence in Portugal – nearly half of all European cases are found there.
the Rac1 Protein and Neuronal Protection
Researchers, led by Márcia Liz, now at the Multidisciplinary Biomedical Research Unit (UMIB) of the Abel Salazar Institute of Biomedical Sciences, focused on the internal structure of nerve cells before degeneration begins. Their inquiry used a mouse model to reveal that changes within nerve cells, specifically in the cytoskeleton that maintains cell shape and function, are associated with excessive activation of the Rac1 protein.
By strategically blocking the activity of Rac1, the team observed important protection of nerve cells. Further investigation revealed a genetic variation in a Rac1 regulator present in some patients with later-stage disease, wich correlates with reduced Rac1 activity and suggests a natural neuroprotective effect.
A New Therapeutic Pathway
This discovery suggests that targeting the Rac1 pathway could provide a new avenue for both preventing and treating foot disease. The research complements existing therapies aimed at reducing transthyretin deposits, offering a more complete approach to managing the condition.Focusing on directly protecting and repairing nerve cell function provides a different and potentially more lasting solution.
| Key Finding | Implication |
|---|---|
| Rac1 protein overactivation | Leads to nerve cell structural changes and dysfunction |
| Rac1 inhibition | Protects nerve cells from degeneration |
| Genetic variation in Rac1 regulator | Supports neuroprotective potential of Rac1 inhibition |
The Future of Amyloidosis Treatment
The research community is actively exploring various therapeutic approaches for amyloidosis, including gene silencing therapies like small interfering RNA (siRNA) to reduce transthyretin production. Tafamidis,a drug approved in several countries,stabilizes transthyretin to prevent misfolding. These advancements, combined with the novel insights from the University of Porto study, pave the way for more effective and targeted treatments.
Did You know? Early diagnosis is crucial in managing Hereditary Transthyretin Amyloidosis, as interventions are more effective before irreversible nerve damage occurs.
Further pre-clinical studies are now planned to translate these findings into potential treatments, ultimately improving the lives of patients suffering from this debilitating disease.
