Asthma drug blocks food allergy reactions in mice

An asthma drug nearly eliminated food allergy reactions in mice, offering potential new protection for millions. The drug Zileuton, which targets leukotrienes, blocked a newly identified gene pathway crucial for regulating anaphylaxis, significantly reducing severe allergic responses in the study. This discovery could lead to a novel treatment for food allergies, a condition affecting over 33 million Americans, and may also explain why some individuals with allergies show no symptoms.
