The Claim
The μ-opioid receptor is expressed on the basolateral membrane of rat colonic goblet cells and human intestinal HT29-MTX cell lines, and activation of this receptor by β-casomorphin-7 or DAMGO increases the expression of MUC2, MUC3, and MUC5AC mucin genes and enhances mucin secretion.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In rat colon cells and human intestinal cell lines, activation of the μ-opioid receptor increases the production and release of specific mucin proteins that protect the intestinal lining.
See the scientific wording
The μ-opioid receptor is expressed on the basolateral membrane of rat colonic goblet cells and on human intestinal HT29-MTX cell lines, and its activation by β-casomorphin-7 or DAMGO triggers increased expression of MUC2, MUC3, and MUC5AC mucin genes and enhanced mucin secretion, demonstrating a direct epithelial pathway for opioid-mediated mucosal protection.
A peptide from milk binds to special receptors on the outer surface of mucus-producing cells in the gut, which turns on genes that make protective mucus proteins and causes the cells to release more of those proteins into the gut lining.
What the research says
1 studyThis study shows that a milk-derived peptide can bind to special receptors on gut mucus-producing cells and make them create more protective mucus — without needing nerves to tell them to. It proves these cells can respond directly to opioids.
