Researchers at Osaka Prefectural University, Japan, have identified for the first time candidates to try to treat people for canine allergies by artificially stimulating immune tolerance to those parts of the molecules that make up dog allergens, creating a “potential dog allergy vaccine.”
Researchers have said that dog allergies are a common disease worldwide and are on the rise. Scientists have been able to identify seven different types of canine allergens, molecules or molecular structures that bind to an antibody and produce an unusually strong immune response that is usually harmless, over the years. These seven are called the familiar Canis Allergens 1 to 7. Of the seven, only one, Can f 1, is responsible for the majority (50-75%) of reactions in people allergic to dogs. Allergens are found in the tissues of dogs’ tongue, salivary glands, and skin.
