Interactions Between Substances Determine Allergenic Potential

Scientists at the University of Gothenburg, Sweden, have used advanced light microscopy to show that a substance can be differently absorbed by the skin, depending on what it is mixed with. This may determine whether it causes contact allergy or not.

"We have also been able to identify specific cells and proteins in the skin with which a contact allergen interacts. The results increase our understanding of the mechanisms behind contact allergy", says Carl Simonsson at the Department of Chemistry, University of Gothenburg.

Salk Discovery May Lead To Safer Treatments For Asthma, Allergies And Arthritis

Glucocorticoids AsthmaScientists have discovered a missing link between the body's biological clock and sugar metabolism system, a finding that may help avoid the serious side effects of drugs used for treating asthma, allergies and arthritis.

In a paper published last week in Nature, scientists at the Salk Institute for Biological Studies report finding that proteins that control the body's biological rhythms, known as cryptochromes, also interact with metabolic switches that are targeted by certain anti-inflammatory drugs.

High Intestinal Microbial Diversity Safeguards Against Allergies

High diversity and a variety of bacteria in the gut protect children against allergies as opposed to some individual bacterial genera. These are the findings of a comprehensive study of intestinal microflora (gut flora) in allergic and healthy children, which was conducted at Linköping University in Sweden.

One hypothesis is that our immune system encounters too few bacteria during childhood, which explains the increasing proportion of allergic children. However it has been difficult to substantiate the hypothesis scientifically.
