“Dust mites, which infest the cleanest homes and thrive in beddings and carpets, disrupt the protective function of the skin, leaving it vulnerable to other allergens and irritants in the environment, a study has found. House dust mites and their droppings have long been linked to attacks of asthma and eczema, and a group of researchers in Japan has offered an explanation as to how that happens. In a paper to be published in the Journal of Investigative Dermatology, the researchers found that mites and their feces contain an enzyme, which destroys the protective function of the skin, leaving it vulnerable to other irritants. ‘People go to hospital only after they develop severe (skin) disease, but little is known as to what happened or what caused it,’ Toshiro Takai of the Atopy (Allergy) Research Center at the Juntendo University School of Medicine in Tokyo told Reuters.” (09/28/06)
