Lower occurrence of atopic dermatitis in children thanks to farm animals and cats

Children whose mothers are exposed to farm animals and cats are better protected against atopic dermatitis and are less likely to develop this painful inflammation of the skin in their first two years of life. A group of researchers from the University of Zurich and other universities have published evidence supporting this theory in the «Journal of Allergy & Clinical Immunology.»

Atopic dermatitis (also known as atopic eczema) is a chronic and extremely painful inflammation of the skin that frequently occurs in early childhood, generally already in infancy. Up to 20 percent of all children in industrialized countries are affected, making it one of the most common childhood skin diseases.

The need to better understand this disease is all the greater considering the intense suffering it causes in small children. Atopic dermatitis is, however, an allergic condition and all allergic reactions result from complex interactions of genetic and environmental factors on the immune system. Earlier research has already indicated that allergies are less common in children who grow up on farms and whose mothers live on farms during their pregnancy. Exposure to farm animals and bacteria frequently found in farms as well as drinking milk from the dairy offer the immune system protection. However, proof of this protective effect in connection with atopic dermatitis has remained elusive.

Now, the «Journal of Allergy & Clinical Immunology» (JACI) has published a study by Caroline Roduit from the research team of Roger Lauener, University of Zurich. The study analyzes how prenatal environmental factors and genetic mechanisms influence the development of atopic dermatitis during the first two years of life. The authors of the study examined children in rural areas of five European countries: Austria, Finland, France, Germany and Switzerland. Of the 1,063 children taking part in the study, 508 were from families that lived on farms, 555 were not farm children.

The researchers were able to demonstrate that women who spend their pregnancy in the proximity of farm animals and cats have children with a reduced risk of developing atopic dermatitis in their first two years of life. The research team also identified two genes in these children that are of vital importance for innate immunity and was able to link the expression of these genes to a lower likelihood of a doctor diagnosis of an allergic condition. The findings of the study are not only significant in the face of the frequency of the disease and the suffering it causes: They also support the theory that gene-environment interaction with the developing immune system influences the development of atopic dermatitis in young children.

Im Focus: Novel light sources made of 2D materials

Physicists from the University of Würzburg have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

So-called monolayers are at the heart of the research activities. These "super materials" (as the prestigious science magazine "Nature" puts it) have been...

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
