A Study of Interstitial Lung Disease Relating to the Development of Fibrosis in the Lungs


About this study

The purpose of this study is to investigate the possibility that B lymphocytes (a kind of white blood cell ) may be contributing to the development of fibrosis in the lungs. This study will examine if B lymphocytes, isolated from  blood, can induce the stimulation of fibroblasts. Fibroblasts are cells that are responsible for the formation of scarring in the lungs. Specific markers found in the surface of B lymphocytes will also be investigated to see if it can be identified why these cells may induce the development of fibrosis.
