Macrophage Diversity in Lung Inflammation and Fibrosis

Macrophages in the lung consist of alveolar macrophages and interstitial macrophages. These cells play important roles in driving pathologic lung inflammation, promoting tissue repair, and contributing to fibrosis. Researchers use single-cell RNA sequencing, spatial transcriptomics, and high-dimensional cytometry to identify distinct macrophage populations and understand how they function during lung disease. 

The Mikacenic Lab investigates macrophage populations in both acute illnesses, such as hypoxemic respiratory failure, and chronic lung diseases, including pulmonary fibrosis associated with autoimmune disease, hypersensitivity pneumonitis, and other forms of interstitial lung disease. 

By characterizing these macrophage populations, the lab aims to better understand how they contribute to inflammation, tissue repair and fibrosis across acute and chronic lung diseases.
