<qa>  What is the name of the study that will measure the effect of the antigen exposure on theThe study will measure the effect of the antigen exposure on the presence and time to presentation of: 1 early clinical markers for asthma development frequent wheezing, wheezing without colds, rhinitis, and atopic dermatitis; 2 early immunologic markers for asthma development eosinophilia, immunoglobulin E; and 3 development of a T-helper phenotype Th-1 vs Th-2. Investigators will characterize the Th phenotype by measuring the whole blood lymphocyte response to stimulants, focusing on Th1 IFN-gamma, interleukin IL-12 and Th2 cytokines IL-10, IL-4, IL-13, as well as real-time reverse transcriptase polymerase chain reaction RT-PCR with PCR amplification TaqMan to quantify RNA transcripts. Clinical and immunologic markers will be measured up to 3 years of age.
