Researchers at Karolinska Institutet in Sweden have studied which genes are expressed in overactive immune cells in mice with asthma-like inflammation of the airways.

The Th2 cell plays a vital part in asthma-related inflammation, but the rarity of these cells and a lack of sensitivity technology has made these cells hard to study in any detail.
