    Abstract Thy-1 was discovered over 50 years ago, and in that time investigators from a broad variety of fields have described numerous and heterogeneous biological functions of Thy-1 in multiple contexts. As an outwardly facing cell surface molecule, it is well positioned to receive extracellular signals; previously reviewed studies have confirmed an important role in cell-cell and cell-matrix adhesion, cell migration, and regulation of outside-in signaling. More recent studies reviewed here expand the repertoire of Thy-1 effects on signaling pathways, and reveal novel roles in mechanotransduction, cellular differentiation, viral entry, and extracellular vesicle binding and internalization. All of these studies contribute to understanding Thy-1 as a context-dependent integrator of a diverse range of extracellular information, and provide impetus for further studies, some of which are suggested here.

    Abstract Fibrosis is a pathological process characterized by accumulation of fibrous connective tissue in organs, leading to organ malfunction and failure. At the cellular level, tissue injury or cellular stress results in aberrant and/or sustained fibroblast "activation" leading to excessive extracellular matrix (ECM) accumulation and remodeling, as well as abnormal crosstalk with other cell types. Fibroblast functions within the fibrotic milieu are broad and complex, but among the most prominent are regulation of tissue architecture via modulation of ECM deposition and synthesis, and production of, activation of, and response to growth factors. Thus, both integrins and growth factor receptors (GFRs) play critical roles in fibroblast orchestration of tissue remodeling. However, the interplay between integrins and GFRs in this context is not fully understood. Their interaction has been described for other diseases, such as cancer. Here, we review the literature relevant to integrin/GFR interactions in the context of fibrosis, classify the known interactions into broad categories, and discuss research opportunities that may yield novel therapeutic targets for a broad range of debilitating chronic diseases.

    Abstract Multipotent mesenchymal stem cells (MSCs) possess regenerative properties and have been shown to improve outcomes and survival in acute and chronic lung diseases, but there have been some safety concerns raised related to MSC-based therapy. Subsequent studies have demonstrated that many of the regenerative effects of MSCs can be attributed to the MSC-derived secretome, which contains soluble factors and extracellular vesicles (EVs). MSC-derived extracellular vesicles (MSC-derived EVs) replicate many of the beneficial effects of MSCs and contain a variety of bioactive factors that are transferred to recipient cells, mediating downstream signaling. MSC-derived EV therapy holds promise as a safe and effective treatment for pulmonary disease, but there remain many scientific and clinical questions that will need to be addressed before EVs are widely applied as a therapy. To date, the use of MSC-derived EVs as a treatment for lung disease has been conducted primarily in in vitro or pre-clinical animal models. In this review, we will discuss the current published research investigating the use of EVs as a potential therapeutic for acute lung injury/acute respiratory distress syndrome (ALI/ARDS), bronchopulmonary dysplasia (BPD), idiopathic pulmonary fibrosis (IPF), pulmonary arterial hypertension (PAH), asthma, and silicosis.

    Abstract Although recent decades have seen the identification, classification and discovery of the genetic basis of many children's interstitial and rare lung disease (chILD) disorders, detailed understanding of pathogenesis and specific therapies are still lacking for most of them. Fortunately, a revolution of technological advancements has created new opportunities to address these critical knowledge gaps. High-throughput sequencing has facilitated analysis of transcription of thousands of genes in thousands of single cells, creating tremendous breakthroughs in understanding normal and diseased cellular biology. Spatial techniques allow analysis of transcriptomes and proteomes at the subcellular level in the context of tissue architecture, in many cases even in formalin-fixed, paraffin-embedded specimens. Gene editing techniques allow creation of "humanized" animal models in a shorter time frame, for improved knowledge and preclinical therapeutic testing. Regenerative medicine approaches and bioengineering advancements facilitate the creation of patient-derived induced pluripotent stem cells and their differentiation into tissue-specific cell types which can be studied in multicellular "organoids" or "organ-on-a-chip" approaches. These technologies, singly and in combination, are already being applied to gain new biological insights into chILD disorders. The time is ripe to systematically apply these technologies to chILD, together with sophisticated data science approaches, to improve both biological understanding and disease-specific therapy.

    Abstract The lung develops from a very simple outpouching of the foregut into a highly complex, finely structured organ with multiple specialized cell types that are required for its normal physiological function. During both the development of the lung and its remodeling in the context of disease or response to injury, gene expression must be activated and silenced in a coordinated manner to achieve the tremendous phenotypic heterogeneity of cell types required for homeostasis and pathogenesis. Epigenetic mechanisms, consisting of DNA base modifications such as methylation, alteration of histones resulting in chromatin modification, and the action of noncoding RNA, control the regulation of information "beyond the genome" required for both lung modeling and remodeling. Epigenetic regulation is subject to modification by environmental stimuli, such as oxidative stress, infection, and aging, and is thus critically important in chronic remodeling disorders such as idiopathic pulmonary fibrosis (IPF), chronic obstructive pulmonary disease (COPD), bronchopulmonary dysplasia (BPD), and pulmonary hypertension (PH). Technological advances have made it possible to evaluate genome-wide epigenetic changes (epigenomics) in diseases of lung remodeling, clarifying existing pathophysiological paradigms and uncovering novel mechanisms of disease. Many of these represent new therapeutic targets. Advances in epigenomic technology will accelerate our understanding of lung development and remodeling, and lead to novel treatments for chronic lung diseases.
