However, available therapies do not specifically target the epithelium and human models of fibrotic epithelial damage with suitability for drug discovery are lacking. We developed a model of the aberrant epithelial reprogramming observed in IPF using alveolar organoids derived from human-induced pluripotent stem cells stimulated with a cocktail of pro-fibrotic and inflammatory cytokines. Deconvolution of RNA-seq data of alveolar organoids indicated that the fibrosis cocktail rapidly increased the proportion of transitional cell types including the KRT5-/KRT17+ aberrant basaloid phenotype recently identified in the lungs of IPF patients. We found that epithelial reprogramming and extracellular matrix (ECM) production persisted after removal of the fibrosis cocktail. We evaluated the effect of the two clinically approved compounds for IPF, nintedanib and pirfenidone, and found that they reduced the expression of ECM and pro-fibrotic mediators but did not completely reverse epithelial reprogramming.

Inhibition of LTβR signalling activates WNT-induced regeneration in lung @article{5ad6043379f04b258bb8e356200ba240, title = "Inhibition of LTβR signalling activates WNT-induced regeneration in lung", abstract = "Lymphotoxin β-receptor (LTβR) signalling promotes lymphoid neogenesis and the development of tertiary lymphoid structures1,2, which are associated with severe chronic inflammatory diseases that span several organ systems3-6. How LTβR signalling drives chronic tissue damage particularly in the lung, the mechanism(s) that regulate this process, and whether LTβR blockade might be of therapeutic value have remained unclear. Here we demonstrate increased expression of LTβR ligands in adaptive and innate immune cells, enhanced non-canonical NF-κB signalling, and enriched LTβR target gene expression in lung epithelial cells from patients with smoking-associated chronic obstructive pulmonary disease (COPD) and from mice chronically exposed to cigarette smoke. Therapeutic inhibition of LTβR signalling in young and aged mice disrupted smoking-related inducible bronchus-associated lymphoid tissue, induced regeneration of lung tissue, and reverted airway fibrosis and systemic muscle wasting. Mechanistically, blockade of LTβR signalling dampened epithelial non-canonical activation of NF-κB, reduced TGFβ signalling in airways, and induced regeneration by preventing epithelial cell death and activating WNT/β-catenin signalling in alveolar epithelial progenitor cells.

Applications and Approaches for Three-Dimensional Precision-Cut Lung Slices. Disease Modeling and Drug Discovery @article{8c023ea68b0146b38f7f2474c606252c, title = "Applications and Approaches for Three-Dimensional Precision-Cut Lung Slices. Disease Modeling and Drug Discovery", abstract = "Chronic lung diseases (CLDs), such as chronic obstructive pulmonary disease, interstitial lung disease, and lung cancer, are among the leading causes of morbidity globally and impose major health and financial burdens on patients and society. Effective treatments are scarce, and relevant human model systems to effectively study CLD pathomechanisms and thus discover and validate potential new targets and therapies are needed. Precision-cut lung slices (PCLS) from healthy and diseased human tissue represent one promising tool that can closely recapitulate the complexity of the lung's native environment, and recently, improved methodologies and accessibility to human tissue have led to an increased use of PCLS in CLD research. Here, we discuss approaches that use human PCLS to advance our understanding of CLD development, as well as drug discovery and validation for CLDs. PCLS enable investigators to study complex interactions among different cell types and the extracellular matrix in the native three-dimensional architecture of the lung. PCLS further allow for high-resolution (live) imaging of cellular functions in several dimensions. Importantly, PCLS can be derived from diseased lung tissue upon lung surgery or transplantation, thus allowing the study of CLDs in living human tissue. Moreover, CLDs can be modeled in PCLS derived from normal lung tissue to mimic the onset and progression of CLDs, complementing studies in end-stage diseased tissue. Altogether, PCLS are emerging as a remarkable tool to further bridge the gap between target identification and translation into clinical studies, and thus open novel avenues for future precision medicine approaches.", keywords = "drug discovery, ex vivo lung disease, PCLS, translation", author = "Alsafadi, {Hani N} and Uhl, {Franziska E.} and Pineda, {Ricardo H.} and Bailey, {Kolene E.} and Mauricio Rojas and Wagner, {Darcy E} and Melanie K{\"o}nigshoff", year = "2020", month = jun, day = "1", doi = "10.1165/rcmb.2019-0276TR", language = "English", volume = "62", pages = "681--691", journal = "American Journal of Respiratory Cell and Molecular Biology", issn = "1044-1549", publisher = "American Thoracic Society", number = "6", } .

Generation of Human 3D Lung Tissue Cultures (3D-LTCs) for Disease Modeling @article{0330851a625b4591ab3b8c43280c3e22, title = "Generation of Human 3D Lung Tissue Cultures (3D-LTCs) for Disease Modeling", abstract = "Translation of novel discoveries to human disease is limited by the availability of human tissue-based models of disease. Precision-cut lung slices (PCLS) used as 3D lung tissue cultures (3D-LTCs) represent an elegant and biologically highly relevant 3D cell culture model, which highly resemble in situ tissue due to their complexity, biomechanics and molecular composition. Tissue slicing is widely applied in various animal models. 3D-LTCs derived from human PCLS can be used to analyze responses to novel drugs, which might further help to better understand the mechanisms and functional effects of drugs in human tissue. The preparation of PCLS from surgically resected lung tissue samples of patients, who experienced lung lobectomy, increases the accessibility of diseased and peritumoral tissue. Here, we describe a detailed protocol for the generation of human PCLS from surgically resected soft-elastic patient lung tissue. Agarose was introduced into the bronchoalveolar space of the resectates, thus preserving lung structure and increasing the tissue's stiffness, which is crucial for subsequent slicing. 500 µm thick slices were prepared from the tissue block with a vibratome. Biopsy punches taken from PCLS ensure comparable tissue sample sizes and further increase the amount of tissue samples. The generated lung tissue cultures can be applied in a variety of studies in human lung biology, including the pathophysiology and mechanisms of different diseases, such as fibrotic processes at its best at (sub-)cellular levels. The highest benefit of the 3D-LTC ex vivo model is its close representation of the in situ human lung in respect of 3D tissue architecture, cell type diversity and lung anatomy as well as the potential for assessment of tissue from individual patients, which is relevant to further develop novel strategies for precision medicine.", author = "Michael Gerckens and Alsafadi, {Hani N} and Wagner, {Darcy E} and Michael Lindner and Gerald Burgstaller and Melanie K{\"o}nigshoff", year = "2019", month = feb, day = "12", doi = "10.3791/58437", language = "English", journal = "Journal of visualized experiments : JoVE", issn = "1940-087X", publisher = "MyJoVE Corporation", number = "144", } .

Differential effects of Nintedanib and Pirfenidone on lung alveolar epithelial cell function in ex vivo murine and human lung tissue cultures of pulmonary fibrosis 11 Medical and Health Sciences 1102 Cardiorespiratory Medicine and Haematology 06 Biological Sciences 0601 Biochemistry and Cell Biology @article{10e39add05064bfab159c71057f8277c, title = "Differential effects of Nintedanib and Pirfenidone on lung alveolar epithelial cell function in ex vivo murine and human lung tissue cultures of pulmonary fibrosis 11 Medical and Health Sciences 1102 Cardiorespiratory Medicine and Haematology 06 Biological Sciences 0601 Biochemistry and Cell Biology", abstract = "Background: Idiopathic pulmonary fibrosis (IPF) is a fatal interstitial lung disease. Repetitive injury and reprogramming of the lung epithelium are thought to be critical drivers of disease progression, contributing to fibroblast activation, extracellular matrix remodeling, and subsequently loss of lung architecture and function. To date, Pirfenidone and Nintedanib are the only approved drugs known to decelerate disease progression, however, if and how these drugs affect lung epithelial cell function, remains largely unexplored. Methods: We treated murine and human 3D ex vivo lung tissue cultures (3D-LTCs; generated from precision cut lung slices (PCLS)) as well as primary murine alveolar epithelial type II (pmATII) cells with Pirfenidone or Nintedanib. Murine 3D-LTCs or pmATII cells were derived from the bleomycin model of fibrosis. Early fibrotic changes were induced in human 3D-LTCs by a mixture of profibrotic factors. Epithelial and mesenchymal cell function was determined by qPCR, Western blotting, Immunofluorescent staining, and ELISA. Results: Low μM concentrations of Nintedanib (1 μM) and mM concentrations of Pirfenidone (2.5 mM) reduced fibrotic gene expression including Collagen 1a1 and Fibronectin in murine and human 3D-LTCs as well as pmATII cells. Notably, Nintedanib stabilized expression of distal lung epithelial cell markers, especially Surfactant Protein C in pmATII cells as well as in murine and human 3D-LTCs. Conclusions: Pirfenidone and Nintedanib exhibit distinct effects on murine and human epithelial cells, which might contribute to their anti-fibrotic action.

In adult lung, alveolar epithelial type (AT) I cells express HOPX and lineage-labeled Hopx+ cells give rise to both ATI and ATII cells after pneumonectomy. However, the cell function of HOPX-expressing cells in adult fibrotic lung diseases has not been investigated. In this study, we have established a flow cytometry-based method to evaluate HOPX-expressing cells in the lung. HOPX expression in cultured ATII cells increased over culture time, which was accompanied by a decrease of proSP-C, an ATII marker. Moreover, HOPX expression was increased in AECs from bleomycin-instilled mouse lungs in vivo. Small interfering RNA-based knockdown of Hopx resulted in suppressing ATII-ATI trans-differentiation and activating cellular proliferation in vitro. In IPF lungs, HOPX expression was decreased in whole lungs and significantly correlated to a decline in lung function and progression of IPF. In conclusion, HOPX is upregulated during early alveolar injury and repair process in the lung.

Senolytic drugs target alveolar epithelial cell function and attenuate experimental lung fibrosis ex vivo @article{b93c7193ef194ef5ba08895df42f2d5e, title = "Senolytic drugs target alveolar epithelial cell function and attenuate experimental lung fibrosis ex vivo", abstract = "Idiopathic pulmonary fibrosis (IPF) is a devastating lung disease with poor prognosis and limited therapeutic options.

The lung alveolar epithelium represents a major site of tissue injury in IPF and senescence of this cell population is probably detrimental to lung repair. However, the potential pathomechanisms of alveolar epithelial cell senescence and the impact of senolytic drugs on senescent lung cells and fibrosis remain unknown. Here we demonstrate that lung epithelial cells exhibit increased P16 and P21 expression as well as senescence-associated β-galactosidase activity in experimental and human lung fibrosis tissue and primary cells.Primary fibrotic mouse alveolar epithelial type (AT)II cells secreted increased amounts of senescence-associated secretory phenotype (SASP) factors in vitro, as analysed using quantitative PCR, mass spectrometry and ELISA. Importantly, pharmacological clearance of senescent cells by induction of apoptosis in fibrotic ATII cells or ex vivo three-dimensional lung tissue cultures reduced SASP factors and extracellular matrix markers, while increasing alveolar epithelial markers.These data indicate that alveolar epithelial cell senescence contributes to lung fibrosis development and that senolytic drugs may be a viable therapeutic option for IPF.", keywords = "Journal Article", author = "Mareike Lehmann and Martina Korfei and Kathrin Mutze and Stephan Klee and Wioletta Skronska-Wasek and Alsafadi, {Hani N.} and Chiharu Ota and Costa, {Ana Rita} and Schiller, {Herbert B} and Michael Lindner and Wagner, {Darcy E} and Andreas G{\"u}nther and Melanie K{\"o}nigshoff", year = "2017", month = aug, doi = "10.1183/13993003.02367-2016", language = "English", volume = "50", pages = "1--15", journal = "European Respiratory Journal", issn = "1399-3003", publisher = "European Respiratory Society", } .

Reduced frizzled receptor 4 expression prevents WNT/b-catenin-driven alveolar lung repair in chronic obstructive pulmonary disease @article{604d14284e80458aa92cbdbc90665997, title = "Reduced frizzled receptor 4 expression prevents WNT/b-catenin-driven alveolar lung repair in chronic obstructive pulmonary disease", abstract = "Rationale: Chronic obstructive pulmonary disease (COPD), in particular emphysema, is characterized by loss of parenchymal alveolar tissue and impaired tissue repair. Wingless and INT-1 (WNT)/b-catenin signaling is reduced in COPD; however, the mechanisms thereof, specifically the role of the frizzled (FZD) family of WNT receptors, remain unexplored. Objectives: To identify and functionally characterize specific FZD receptors that control downstream WNT signaling in impaired lung repair in COPD. Methods: FZD expression was analyzed in lung homogenates and alveolar epithelial type II (ATII) cells of never-smokers, smokers, patients with COPD, and two experimental COPD models by quantitative reverse transcriptase-polymerase chain reaction, immunoblotting, and immunofluorescence. The functional effects of cigarette smoke on FZD4, WNT/b-catenin signaling, and elastogenic components were investigated in primary ATII cells in vitro and in three-dimensional lung tissue cultures ex vivo. Gain- and loss-of-function approaches were applied to determinethe effects of FZD4 signaling on alveolar epithelial cell wound healing and repair, as well as on expression of elastogenic components. Measurements and Main Results: FZD4 expression was reduced in human and experimental COPD lung tissues as well as in primary human ATII cells from patients with COPD. Cigarette smoke exposure down-regulated FZD4 expression in vitro and in vivo, along with reduced WNT/b-catenin activity. Inhibition of FZD4 decreased WNT/b-catenin-driven epithelial cell proliferation and wound closure, and it interfered with ATII-to-ATI cell transdifferentiation and organoid formation, which were augmented by FZD4 overexpression. Moreover, FZD4 restoration by overexpression or pharmacological induction led to induction of WNT/b-catenin signaling and expression of elastogenic components in threedimensional lung tissue cultures ex vivo.

CONFERENCE ABSTRACT
LSC - 2017 - Hippo-YAP/TAZ signaling is deranged in IPF @article{a3e0f54a867745e4a427186811d856e3, title = "LSC - 2017 - Hippo-YAP/TAZ signaling is deranged in IPF", abstract = "Objective: Idiopathic pulmonary fibrosis (IPF) is a devastating disease with no cure and is characterized by deranged epithelial repair, myofibroblast activation, and excess deposition of extracellular matrix. Yes associated protein (YAP) and transcriptional co-regulator with PDZ-binding domain(TAZ), co-transcriptional activators of the Hippo pathway and proto-oncogenes, were recently found to be deranged in IPF. The cause of their dysregulation remain unknown. Hippo signaling regulates several endogenous progenitor cell functions through YAP/TAZ. We hypothesized that Hippo signaling is downregulated in IPF, resulting in increased YAP/TAZ activity.Methods and Results: We assessed normal and fibrotic (IPF or intratracheal bleomycin-treated murine) lung tissue using immunohistochemistry, qPCR, and Gene Set Enrichment Analysis to identify cell types with deranged YAP/TAZ. Distal epithelial cells and fibroblasts were found to have dysregulated YAP/TAZ activity. Hippo components were downregulated in IPF and fibrotic mice, including in murine alveolar type II cells (mATII). Secretion of YAP/TAZ targets with pro-fibrotic activity was increased in fibrotic mATII as detected by mass spectrometry proteomics. Principal component analysis using Hippo expression in the Lung Gene Research Consortium separated IPF from normal patients. Fibrotic markers, including YAP/TAZ targets and myofibroblast activation, were reduced in the bleomycin model of fibrosis and in a novel ex vivo model of early pulmonary fibrosis in human precision cut lung slices when verteporfin, an FDA approved drug and YAP/TAZ inhibitor, was used therapeutically.Conclusion: Hippo-YAP/TAZ are deranged in IPF. Pharmaceutical targeting of YAP/TAZ and or restoration of Hippo signaling may represent a new therapeutic strategy for IPF.", author = "Darcy Wagner and Hani Alsafadi and Kathrin Mutze and Rita Costa and Marlene Stein and Herbert Schiller and Naftali Kaminski and Melanie Koenigshoff", year = "2017", month = sep, day = "6", doi = "10.1183/1393003.congress-2017.OA475", language = "English", volume = "50", journal = "European Respiratory Journal", issn = "0903-1936", publisher = "European Respiratory Society", number = "Suppl. 61", } .
