Overview
Dr. Quan’s project, The Role of Dendritic Cells in Interstitial Lung Disease Associated with Rheumatoid Arthritis, tests a new model which examines fibrosis in the context of well known inflammatory cells, myeloid dendritic cells (mDC), that may link inflammation to fibrosis. Myeloid dendritic cells promote fibrosis by producing collagen and are thus key players in interstitial lung disease associated with rheumatoid arthritis.
