Children who live on farms that produce milk run one-tenth the risk of developing allergies as other rural children.
According to researchers at The University of Gothenburg, Sweden, pregnant women may benefit from spending time on dairy farms to promote maturation of the fetal and neonatal immune system.
The occurrence of allergic diseases has risen dramatically in Western societies. One frequently cited reason is that children are less exposed to microorganisms and have fewer infections than previous generations, thereby delaying maturation of the immune system.
A study by researchers at Sahlgrenska Academy, University of Gothenburg, monitored children until the age of three to examine maturation of the immune system in relation to allergic disease. All of the children lived in rural areas of the Västra Götaland Region, half of them on farms that produced milk.
Lower risk of allergy
The study found that children on dairy farms ran a much lower risk of developing allergies than the other children.
“Our study also demonstrated for the first time that delayed maturation of the immune system, specifically B-cells, is a risk factor for development of allergies,” says Anna-Carin Lundell, one of the researchers.
Need for additional studies
Children with an allergic disease at the age of 18 and 36 months had a higher percentage of immature B-cells in their blood circulation at birth and during the first month of life. Additional studies are needed to corroborate the correlation between delayed B-cell maturation during the neonatal period and the risk for subsequent development of allergies.
The Gothenburg researchers will start off by examining children as they turn eight.
“We need to identify the specific factors on dairy farms that strengthen protection against allergies and appear to promote maturation of the immune system as early as the fetal stage,” Ms. Lundell says.
The article High proportion of CD5+ B-cells in infants predicts development of allergic disease was published online in The Journal of Immunology on June 13.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
