Journal Article
Clements, D., Miller, S., Babaei-Jadidi, R., Adam, M., Potter, S. S., & Johnson, S. R. (2022). Cross talk between LAM cells and fibroblasts may influence alveolar epithelial cell behavior in lymphangioleiomyomatosis. AJP - Lung Cellular and Molecular Physiology, 322(2), L283-L293. https://doi.org/10.1152/AJPLUNG.00351.2021

Lymphangioleiomyomatosis (LAM) is a female-specific cystic lung disease in which tuberous sclerosis complex 2 (TSC2)-deficient LAM cells, LAM-associated fibroblasts (LAFs), and other cell types infiltrate the lungs. LAM lesions can be associated with... Read More about Cross talk between LAM cells and fibroblasts may influence alveolar epithelial cell behavior in lymphangioleiomyomatosis.

Mast Cell Tryptase Release Contributes to Disease Progression in Lymphangioleiomyomatosis (2021)
Journal Article
Babaei-Jadidi, R., Dongre, A., Miller, S., Castellanos Uribe, M., Stewart, I. D., Thompson, Z. M., …Johnson, S. R. (2021). Mast Cell Tryptase Release Contributes to Disease Progression in Lymphangioleiomyomatosis. American Journal of Respiratory and Critical Care Medicine, 204(4), 431-444. https://doi.org/10.1164/rccm.202007-2854OC

Rationale: Lymphangioleiomyomatosis (LAM) is a multisystem disease that causes lung cysts and respiratory failure. Loss of TSC (tuberous sclerosis complex) gene function results in a clone of “LAM cells” with dysregulated mTOR (mechanistic target of...

ECM crosslinking enhances fibroblast growth and protects against matrix proteolysis in lung fibrosis (2017)
Journal Article
Philp, C. J., Siebeke, I., Clements, D., Miller, S., Habgood, A., John, A. E., …Johnson, S. R. (2018). ECM crosslinking enhances fibroblast growth and protects against matrix proteolysis in lung fibrosis. American Journal of Respiratory Cell and Molecular Biology, 58(5), 594–603. https://doi.org/10.1165/rcmb.2016-0379OC

Idiopathic pulmonary fibrosis (IPF) is characterised by accumulation of extra cellular matrix (ECM) proteins and fibroblast proliferation. ECM cross-linking enzymes have been implicated in fibrotic diseases and we hypothesised that the ECM in IPF is...

Cathepsin K in lymphangioleiomyomatosis: LAM cell-fibroblast Interactions enhance protease activity by extracellular acidification (2017)
Journal Article
Dongre, A., Clements, D., Fisher, A. J., & Johnson, S. R. (2017). Cathepsin K in lymphangioleiomyomatosis: LAM cell-fibroblast Interactions enhance protease activity by extracellular acidification. American Journal of Pathology, 187(8), 1750-1762. https://doi.org/10.1016/j.ajpath.2017.04.014

Lymphangioleiomyomatosis (LAM) is a rare disease in which clonal ‘LAM’ cells infiltrate the lungs and lymphatics. In association with recruited fibroblasts, LAM cells form nodules adjacent to lung cysts. It is assumed LAM nodule derived proteases lea...

MMP-1 activation contributes to airway smooth muscle growth and asthma severity (2016)
Journal Article
Naveed, S., Clements, D., Jackson, D. J., Philp, C., Billington, C. K., Soomro, I. N., …Johnson, S. R. (2017). MMP-1 activation contributes to airway smooth muscle growth and asthma severity. American Journal of Respiratory and Critical Care Medicine, 195(8), 1000-1009. https://doi.org/10.1164/rccm.201604-0822OC

Introduction: Matrix metalloproteinase-1 and mast cells are present in the airways of people with asthma. We hypothesised that matrix metalloproteinase-1 could be activated by mast cells and increase asthma severity. Methods: Patients with stable ast...

PLoS ONE, 9(2), Article e90565. https://doi.org/10.1371/journal.pone.0090565

Airway remodelling describes the histopathological changes leading to fixed airway obstruction in patients with asthma and includes extra-cellular matrix (ECM) deposition. Matrix metalloproteinase-1 (MMP-1) is present in remodelled airways but its re...
