Gut microbes from healthy infants block milk allergy development in mice
New research suggests that the gut microbiome may help prevent the development of cow's milk allergy. Scientists at the University of Chicago found that gut microbes from healthy human infant donors transplanted into mice protected animals exposed to milk from experiencing allergic reactions, while gut microbes transplanted from infants allergic to milk did not. The work, described online today in Nature Medicine, was supported in part by NIAID. (2019-01-14)

CRISPR study reveals new immune system regulators
Scientists have created the first retroviral CRISPR-Cas9 gene editing library to explore the regulation of mouse T cells, which are key cells in the immune system.

Enzyme lays the foundations for allergic immune response
While in search of the causes of allergies and asthma, a chance discovery has yielded new clues: researchers led by Dr Marcus Peters have ascertained that the enzyme guanylate cyclase in cells lays the foundations for the type of immune response. Allergic symptoms are more or less pronounced depending on which immune response gains the upper hand. 'This is particularly interesting as there are active pharmaceutical ingredients that stimulate the enzyme or even inhibit it,' explains Marcus Peters. (2018-07-23)

Major study identifies new hay fever risk genes
In a large international study involving almost 900,000 participants, researchers from the University of Copenhagen and COPSAC have found new risk genes for hay fever. It is the largest genetic study so far on this type of allergy, which affects millions of people around the world. (2018-07-17)

Children with existing allergies should be screened for an emerging, severe chronic food allergy
Children with known skin, food and respiratory allergies should be screened for an emerging, chronic food allergy called eosinophilic esophagitis (EoE), a painful inflammation of the esophagus, the food tube between the mouth and stomach. Pediatric allergists who analyzed a very large group of children from birth to adolescence say that EoE should be considered a later component of the 'allergic march' -- the natural history in which many children successively develop a series of allergies. (2018-06-25)
