Repair after injury is a fundamental biologic process that is essential for lung health. Our lab studies the role of phagocytes and phagocytosis during tissue repair. We explore how the different types of “meals” engulfed by phagocytes uniquely impact phagocyte function. In particular, we are interested in how engulfment of apoptotic cells and other cell corpses is able to prime phagocytes for repair. We are also working to understand the heterogeneity of lung phagocytes, particularly macrophages, and describe their locations and functions following lung injury.
Current Projects
- Macrophage metabolic response to apoptotic cell engulfment
- Fibroblast-cell corpse interactions during lung repair
- Macrophage heterogeneity in the lung
