Potential of Glycoprotein Reelin in Treating Leaky Gut and Severe Depression
Research from the University of Victoria suggests that the glycoprotein reelin may offer new hope for treating both leaky gut syndrome and severe depression by restoring gut integrity and improving mood symptoms.
Recent research from the University of Victoria highlights the promising role of a glycoprotein called reelin in addressing both 'leaky gut' syndrome and severe depression. Chronic stress and related psychiatric conditions can impair the gut barrier's integrity, leading to increased permeability, commonly known as leaky gut. This condition allows harmful bacteria and toxins to enter circulation, triggering immune responses and inflammation that may worsen depressive symptoms.
The study, published in Chronic Stress, investigated how reelin, a protein present throughout the body—including in the brain, blood, liver, and intestines—may restore gut health and alleviate depression. Findings revealed that chronic stress decreases reelin levels in the intestines of preclinical models, but a single injection of 3 micrograms of reelin successfully normalized these levels.
This is significant because lower reelin levels have been observed in individuals with major depressive disorder (MDD) and in stressed rodents. Notably, reelin injections have shown antidepressant-like effects and support gut lining renewal. Given that the gut lining is renewed every four to five days under healthy conditions, reelin’s protective role could prevent the progression of leaky gut and subsequent inflammatory responses that exacerbate depression.
Professor Hector Caruncho explained that reelin's presence in the gut-brain axis positions it as a potential therapeutic candidate for psychiatric disorders linked to gastrointestinal health. While further research is necessary before reelin becomes part of clinical treatment, these findings suggest that targeting reelin could offer a dual approach to managing depression and gastrointestinal conditions, especially for individuals suffering from both.
This groundbreaking research emphasizes the interconnectedness of gut health and mental health, proposing a novel pathway for therapies that support both physical and psychological well-being.
