Special Gut Protein Neutralises Bacteria, Study Finds

Researchers have found that a specific protein in the gut plays an important role in fighting bacteria. This discovery could help create treatments for diseases like inflammatory bowel disease.

The protein, called intelectin-2, is not new, but its function in the gastrointestinal (GI) tract was unclear. Intelectin-2 belongs to a group of proteins known as lectins, which attach to certain sugar molecules.

A team from MIT discovered that intelectin-2 helps in two ways. First, it connects mucus molecules in the GI tract, making the mucus barrier stronger to protect the intestinal tissues. If this barrier is damaged, intelectin-2 can also recognise and trap bacterial cells, either stopping their growth or killing them.

The researchers used various methods to study intelectin-2, including examining mouse and human tissue. They found that intelectin-2 targets galactose, a simple sugar found in mucus and on some bacterial surfaces. When it binds to bacteria, the bacteria break down over time.

Some of the bacteria that intelectin-2 fights have become resistant to antibiotics. These include Staphylococcus aureus, which can cause serious infections. Researchers believe that understanding and using proteins like intelectin-2 may lead to new ways to treat bacterial infections.
