A Human Milk Oligosaccharide Protects Against Intestinal Infection and Inflammation

A Human Milk Oligosaccharide Protects Against Intestinal Infection and Inflammation

Sugars found in human milk, called human milk oligosaccharides (HMOs), have various protective effects against intestinal infections. A new study finds that the HMO 2'-fucosyllactose (2'-FL) protects against infection and inflammation caused by the pathogen Campylobacter jejuni. Read More...

Maternal Milk Antibodies Prepare Newborn Mice to Host Commensal Gut Microbes

Maternal Milk Antibodies Prepare Newborn Mice to Host Commensal Gut Microbes

Our immune system protects us from many harmful microbes, but in doing so it needs to be able to differentiate between friend and foe. Our bodies harbor many beneficial gut bacteria that play important roles in digestion and immunity, and our immune system needs to react differently to these microbes compared with harmful pathogens.

Prolactin Targets Intestines Too

Prolactin Targets Intestines Too

Prolactin (PRL) is a hormone that, as its name clearly indicates, PROmotes LACTation. Although it is best known for initiating milk production in the mammary glands, prolactin actually targets numerous other tissues throughout the body during lactation. One important target is the gut, where prolactin is believed to influence calcium absorption. A new study confirms this hypothesis, demonstrating that prolactin increases the ability of the intestines to absorb calcium and transfer it to the bloodstream. These important findings show that although PRL may have the important job of telling the mammary glands to make milk, it also plays a critical role in making sure that milk has all of the necessary ingredients.

Creating Therapeutic Yogurt for Treatment of Arthritis

Consuming dairy products, such as milk or yogurt, is known to be good for general health. New research may make dairy products even more beneficial by enabling them to treat certain autoimmune diseases such as arthritis. Read More...

Identifying Parasites in African Cattle

Identifying Parasites in African Cattle

When African cattle become lazy and their milk production drops, they are said to have 'nagana'-to be depressed, in Zulu. The biological cause of nagana is a parasite, of which there are several species, and which wiggle around like winding corkscrews under a microscope. To work out how to reduce the damage done by these 'trypanosome' parasites, and thus improve the lot of many poor cattle farmers, we need better diagnostics. Recently, a group of researchers in Vienna invented a means of testing for three different species of trypanosome at the same time. Read about their breakthrough here! Read More...
