JAM2 Activation – Leaky Gut Syndrome

Understanding Leaky Gut Syndrome

Leaky Gut Syndrome (also known as increased intestinal permeability) occurs when the tight junctions between cells in the intestinal lining become compromised. This allows undigested food particles, bacterial toxins, and other substances to pass into the bloodstream, potentially triggering systemic inflammation and immune responses. Increased intestinal permeability is well-documented in scientific literature and is associated with conditions such as irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), celiac disease, and various autoimmune disorders. While not everyone experiences symptoms, it is increasingly recognized as a contributing factor in chronic health issues. Estimates suggest that a significant portion of the population may have some degree of compromised gut barrier function, particularly with aging, poor diet, stress, or antibiotic use.

There is also growing evidence linking leaky gut to increased permeability of the blood-brain barrier in older age. The same inflammatory processes and tight junction disruptions that weaken the intestinal barrier may similarly affect brain endothelial cells, potentially contributing to neuroinflammation and age-related cognitive decline.
