Asthma
Conditions
Brief summary
This will be a single center study of asthmatic subjects and healthy controls which will investigate mechanisms of asthma through detailed molecular analysis of airway tissues and fluids. The primary goal will be investigate the role of microRNAs in Th2-driven inflammation in asthma. The investigators hypothesize that asthma is associated with abnormal expression of miRNAs in T cells which favors differentiation into Th2-cells. The investigators further hypothesize that asthma is heterogeneous based on the presence and absence of Th2-driven inflammation and that abnormalities in T cell miRNA expression will be most prominent in a subgroup with high levels of Th2-driven inflammation (as assessed using molecular markers that the investigators have previously established). Finally, the investigators hypothesize that inhaled corticosteroids will normalize the T-cell miRNA abnormalities observed in asthma, as corticosteroids treat Th2-driven inflammation. The samples collected will also facilitate the pursuit of secondary analyses designed to investigate mechanisms of inflammation and remodeling in asthma as well as molecular phenotypes of asthma.

Primary
Difference in Baseline T Cell miRNA Expression Between Asthmatics and Healthy Controls
Identification of T cell miRNAs which are differentially expressed in asthma as compared to healthy controls. The investigators will measure a panel of \ 200 miRNAs by qPCR (yielding normalized copy numbers for each miR) and identify differential expressed based on a false discovery rate \<0.05. Normalized copy numbers from this qPCR experiment were established using the global mean-normalization approach as described in the paper by Barbara D'haene et al. entitled miRNA expression profiling - from reference genes to global mean normalization published in MicroRNA Expression profiling Methods and Protocols, Springer Verlag, Feb 2011.
Time frame: Baseline (cross-sectional analysis)
Population: The study enrolled two groups of subjects: 1. Healthy Non-asthmatic Controls, 2. Asthmatics (who were subsequently randomized to inhaled corticosteroids or no treatment). This analysis compares pre-randomization values in group 1 healthy non-asthmatics controls to group 2 asthmatics because the scientific goal is to identify miRNAs differentially expressed in asthma.
