Scientists discover what triggers allergic reactions to cats

Scientists have discovered the trigger for allergic reactions to cats, paving the way for developing preventative treatments.

A team at the University of Cambridge looked at the immune system's extreme reaction to cat allergens and discovered that the most common cause of severe allergic reactions are because of the Fel d 1 protein found in particles of cat skin, know as cat dander.

In a study published in the Journal of Immunology, researchers found that cat allergens activate a pathway in the body when in the presence of a common environmental bacterial toxin know as LPS.
