The human dander atopy. I. The prototype of auto-atopy.

Human dander is shown to be a true allergen giving skin reactions most frequently in atopic patients. The clinical importance of human dander is discussed and data of a group of patients atopic only to human dander are given. It seems probable that human dander is an auto allergen and that there are many more auto allergens to which the atopic organism produces IgE-type antibodies.
