Pig stomach mucins are effective as anti-viral agents for consumer products

26.04.2012
Scientists are reporting that the mucus lining the stomachs of pigs could be a long-sought, abundant source of "mucins" being considered for use as broad-spectrum anti-viral agents to supplement baby formula and for use in personal hygiene and other consumer products to protect against a range of viral infections. Their study appears in ACS' journal Biomacromolecules.

In the report, Katharina Ribbeck and colleagues point out that mucus, which coats the inside of the nose, mouth and vagina, is the immune system's first line of defense. The slimy secretion traps disease-causing microbes, ranging from influenza virus to HIV (which causes AIDS) before they can cause infection.

That has led to consideration of mucin, the main component of mucus, for use as an anti-viral agent in a variety of products. However, existing sources of mucins, such as breast milk, cannot provide industrial-sized quantities. Large amounts of mucus exist in the lining of pigs' stomachs, and the authors set out to determine if pig mucus — already used as a component of artificial saliva to treat patients with "dry mouth," or xerostomia — has the same anti-viral activity.

They found that pig mucus is effective at blocking a range of viruses, from strains of influenza to the human papilloma virus, which is associated with cervical and oral cancer. They report that pig mucins could be added to toothpastes, mouthwashes, wound ointments and genital lubricants to protect against viral infections. "We envision porcine gastric mucins to be promising antiviral components for future biomedical applications," the report says.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
