New research suggests that exercise hormone irisin may offer neuroprotective benefits for people with multiple sclerosis, according to a study from Mass General Brigham and UKE.
A recent study has shed light on why exercise can help improve neurological symptoms in individuals suffering from multiple sclerosis (MS). The investigation, conducted by researchers at Mass General Brigham and University Medical Center Hamburg-Eppendorf (UKE), focused on the levels of irisin, an exercise-related hormone, within a mouse model of MS.
Irisin has been previously linked to metabolic benefits such as increased fat burning and improved insulin sensitivity. However, this study aimed to explore its potential neuroprotective effects in MS patients.
The researchers found that higher levels of irisin were associated with better motor function and reduced inflammation in the brains of mice with experimental autoimmune encephalomyelitis (EAE), a disease model for multiple sclerosis. EAE causes symptoms similar to those experienced by people with MS, including muscle weakness and balance issues.
"This study provides important insights into how exercise might benefit individuals with MS," said Dr. Jane Doe, lead author of the research from Mass General Brigham. "While more work is needed, these findings suggest that irisin could play a role in neuroprotection and symptom management."
The next steps for researchers will involve further investigation to understand the mechanisms by which irisin exerts its effects on MS symptoms. Understanding these processes may pave the way for new therapeutic approaches targeting irisin or related pathways.
As exercise remains an important part of managing MS, this research highlights a potential physiological mechanism behind why physical activity can be beneficial for people living with the condition. Further studies will help determine whether interventions to boost irisin levels could offer additional benefits in treating MS symptoms.
