The CRONIC-PPF Faculty
Grażyna Kwapiszewska is a molecular biologist with a strong research focus on the complex processes underlying vascular
remodeling and the role of endothelial cells in pulmonary arterial hypertension (PAH) and pulmonary hypertension (PH)-ILD. Recently,
she has characterized a specialized extracellular matrix, the basal membrane and its products (matrikines), in different forms of
PH-ILD. She will contribute to this doc.funds with her know how of endothelial and smooth muscle cells, extracellular matrix and
cellular signaling. She served as speaker of the doc.fund RESPImmun and is a vice-speaker of the Lung Research Cluster.

Immune activation of endothelial cells paves the way to progressive pulmonary fibrosis

Research interests
- We have shown in series of studies that vascular component is involved in chronic lung diseases (CLD). We
have performed first compartment specific transcriptomic studies on pulmonary arteries revealing
underlying molecular differences in remodeled pulmonary arteries from different forms of CLD. By applying
Fra-2 transgenic mouse model of systemic sclerosis, we documented that vascular remodeling
proceeded parenchymal involvement and that skewing inflammation towards Th2 worsens the phenotype.

- Identified extensive changes in basement membrane components as potential breaking point in vascular
homeostasis and crucial interaction point between EC and inflammatory cells. We have also established
extensive and deep immune cell phenotyping of vascular compart and identified changes in rare
inflammatory populations which might serve as a source of proteolytic enzymes leading to the remodeling
processes.

- Delineated the fate of major vascular resident cell populations in remodeling process showing distinct
structural and compartment specific contribution of smooth muscle actin and PDGFRA-positive cells.
We have also shown that lipid rich fibroblasts protect from the development of lung fibrosis. Finally,
we have delineated the key role of cytoskeletal components in mediating smooth muscle cells proliferative
response.
