Treatment for asthma and allergy

Abstract

Several genes are upregulated in the lung of asthma or allergy sufferers. Many of the genes up-regulated in asthma are involved in arginine metabolism in the lung. Moreover, a set of 291 signature genes was found that can be used to indicate a patient's predilection for developing asthma or the patient's degree of suffering. Also, a set of 59 signature genes were found that indicate a patient's predilection for developing allergies. Many of the up-regulated genes relating to asthma were from the arginine metabolic pathway. Other genes, such as ADAM8, SPRR2A and SPRR2B were also strongly up-regulated in asthma. Treatment of asthma may be accomplished by administering compositions which decrease the levels of Arginase I, Arginase II, CAT2, or other arginase pathway members in the lung. Additionally, detection of altered levels of these proteins or the mRNA encoding them may be useful to diagnose the presence of asthma in a patient.
