Study uncovers mechanism responsible for pollen-induced allergies

Posted: 22 Jul 2015 08:56 AM PDT

When people are exposed to airborne allergens such as pollens, their immune system responds by sending neutrophils to the airways. Neutrophils are a type of white blood cells that move quickly to a site of injury or invading infection and cause inflammation. Now, a mechanism that is central to becoming allergic to ragweed pollen and developing allergic asthma or seasonal nasal allergies has been identified by a new study.

Hereditary swellings caused by defective blood protein

Posted: 20 Jul 2015 01:18 PM PDT

Hereditary angioedema type III is a rare, hereditary, and serious disorder, characterized by painful swellings in the skin and other organs. An international team of scientists has published a study in which they show that the disease is caused by a defective blood protein, the so-called coagulation factor XII. The results from this study may contribute to future treatment strategies for patients with the disease.

Role of microbiota in preventing allergies

Posted: 10 Jul 2015 06:52 AM PDT

The microbiota is involved in many mechanisms, including digestion, vitamin synthesis and host defense. It is well established that a loss of bacterial symbionts promotes the development of allergies. Scientists have succeeded in explaining this phenomenon, and demonstrate how the microbiota acts on the balance of the immune system: the presence of microbes specifically blocks the immune cells responsible for triggering allergies.
