The purpose of this study is to obtain biologic materials from the blood, airways and/or urine of normal individuals and individuals with lung disease. The normal are used to establish a set of normal ranges for various parameters. These provide control information when compared to individuals with various pulmonary diseases, and will help in understanding of the etiology and pathogenesis of various lung diseases. The underlying hypothesis is that the pathologic morphological changes in the airway epithelium must be preceded by changes in the gene expression pattern of the airway epithelium and potentially in macrophages.

Establishing normal ranges for various parameters
The primary objective of the study is to obtain biologic materials from the blood, airways and/or urine of normal individuals and individuals with lung disease. The normal are used to establish a set of normal ranges for various parameters. These provide control information when compared to individuals with various pulmonary diseases, and will help in understanding the etiology and pathogenesis of various lung diseases.
Learning about the genetic composition of the airway cells
The secondary objective is to learn more about the genetic composition the cells that line the airways (windpipes) of the lungs in normal individuals and in individuals with lung disease.
