Abstract
Current understanding of mechanisms of ischemia-reperfusion-induced lung injury during lung preservation and transplantation is mainly based on clinical observations and animal studies. Herein, we used cell and systems biology approaches to explore these mechanisms at transcriptomics levels, especially by focusing on the differences between human lung endothelial and epithelial cells, which are crucial for maintaining essential lung structure and function. Human pulmonary microvascular endothelial cells and human lung epithelial cells were cultured to confluent, subjected to different cold ischemic times (CIT) to mimic static cold storage with preservation solution, and then subjected to warm reperfusion with a serum containing culture medium to simulate lung transplantation. Cell morphology, viability, and transcriptomic profiles were studied. Ischemia-reperfusion injury induced a CIT time-dependent cell death, which was associated with dramatic changes in gene expression. Under normal control conditions, endothelial cells showed gene clusters enriched in the vascular process and inflammation, while epithelial cells showed gene clusters enriched in protein biosynthesis and metabolism. CIT 6 h alone or after reperfusion had little effect on these phenotypic characteristics. After CIT 18 h, protein-biosynthesis-related gene clusters disappeared in epithelial cells; after reperfusion, metabolism-related gene clusters in epithelial cells and multiple gene clusters in the endothelial cells also disappeared. Human pulmonary endothelial and epithelial cells have distinct phenotypic transcriptomic signatures. Severe cellular injury reduces these gene expression signatures in a cell-type-dependent manner. Therapeutics that preserve these transcriptomic signatures may represent new treatment to prevent acute lung injury during lung transplantation.

Induced Pluripotent Stem Cells Attenuate Acute Lung Injury Induced by Ischemia Reperfusion via Suppressing the High Mobility Group Box-1. Dose Response 2020; 18:1559325820969340. [PMID: 33192202 PMCID: PMC7607776 DOI: 10.1177/1559325820969340] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 10/06/2020] [Accepted: 10/07/2020] [Indexed: 11/24/2022] Open
Abstract
Pulmonary endothelial cell injury is a hallmark of acute lung injury. High-mobility group box 1 (HMGB1) can modulate the inflammatory response via endothelial cell activation and release of inflammatory molecules. Thus, we tested whether induced pluripotent stem cells (iPSCs) can alleviate ischemia/reperfusion (I/R) induced lung injury, and, if so, whether HMGB1 mediates the effect in a male C57BL/6 mouse model. Intravenously injected iPSCs into mice 2 h after I/R showed a significant attenuation of lung injury (assessed by lung mechanics, edema, and histology) 24 h after reperfusion (compared with controls), along with decreases in HMGB1, phosphorylated nuclear factor-κB, inflammatory cytokines [interleukin (IL)1β, IL6 and tumor necrosis factor-α], and the activation of endothelial cells. Furthermore, these effects of iPSCs can be mimicked by blocking HMGB1 with an inhibitor in vivo and in vitro. We conclude that iPSCs can be a potential therapy for I/R-induced lung injury. These cells may exert therapeutic effects through blocking HMGB1 and inflammatory cytokines.
