In mice with type 2 diabetes, a water extract from mulberry leaves is linked to higher levels of occludin, a protein that helps maintain the integrity of the intestinal barrier.
Mechanism
Synthesis from 1 study
The extract changes the gut bacteria to reduce harmful toxins that cause inflammation, which lets the intestinal wall repair its protective seal. It also calms down other inflammatory signals in the gut, helping the barrier proteins rebuild.
Most probable mechanism
Good bacteria in the gut increase after the extract is consumed, which reduces harmful substances that leak from the intestines. This lowers inflammation in the gut lining, allowing the glue-like proteins between intestinal cells to rebuild and seal the barrier more tightly.
The extract alters the composition of gut bacteria, increasing beneficial genera and reducing those that produce lipopolysaccharide (LPS)
Reduced LPS-producing bacteria decrease the amount of bacterial endotoxin crossing the intestinal barrier into the bloodstream
Lower systemic LPS reduces activation of inflammatory pathways triggered by Toll-like receptor 4
Decreased inflammation in the intestinal tissue allows for increased expression of tight junction proteins, including occludin
Restored occludin expression strengthens the physical barrier between intestinal cells, reducing permeability and preventing further endotoxin leakage
Less supported by current evidence, but not ruled out
The extract reduces levels of certain signaling molecules in the gut that promote inflammation, which allows the cells lining the intestine to repair their tight connections.
The extract decreases the production of endocannabinoids anandamide and 2-arachidonoylglycerol in the liver and ileum
The extract increases the activity of enzymes that break down these endocannabinoids
Lower endocannabinoid levels reduce signaling through cannabinoid receptor 1, which is linked to intestinal inflammation and barrier disruption
Reduced receptor signaling decreases inflammatory mediators in the ileum, creating a permissive environment for occludin expression
