Research Interest
Dr. Zhou’s research work has been focused on the signaling pathways related to extracellular matrix turnover and the role and function of chemoattractant molecules in primary human lung fibroblasts. Specifically, her work involves:
1.Cellular responses to IL-13 and TGF-ß in fibroblasts during lung inflammation and repair in asthma. Dr. Zhou’s studies focus on the TGF-ß and IL-4Ra signaling pathways on extracellular matrix metabolism, airway inflammation and remodeling in primary human fibroblasts obtained from normal and asthmatic subjects.
2.Regional fibroblasts heterogeneity in asthma. Dr. Zhou has been interested in regulatory mechanisms that determine the differences between fibroblasts isolated from proximal and distal lung. Dr. Zhou has successfully transfected primary human lung fibroblasts with dominant negative constructs or siRNA, and would like to fully understand the mechanisms controlling their phenotypic differences using an epigenetic approach.
