Abstract
Psychiatric disorders are common in patients with allergic asthma, and they can have a significant impact on their quality of life and disease control. Recent studies have suggested that there may be potential immune-brain communication mechanisms in asthma, which can activate inflammatory responses in different brain areas, leading to structural and functional alterations and behavioral changes. However, the precise mechanisms underlying these alterations remain unclear. In this paper, we comprehensively review the relevant research on asthma-induced brain structural and functional alterations that lead to the initiation and promotion of anxiety. We summarize the possible pathways for peripheral inflammation to affect the brain's structure and function. Our review highlights the importance of addressing neuropsychiatric disorders in the clinical guidelines of asthma, to improve the quality of life of these patients. We suggest that a better understanding of the mechanisms underlying psychiatric comorbidities in asthma could lead to the development of more effective treatments for these patients.

Epithelial LIF signaling limits apoptosis and lung injury during bacterial pneumonia. Am J Physiol Lung Cell Mol Physiol 2022; 322:L550-L563.

Abstract
During bacterial pneumonia, alveolar epithelial cells are critical for maintaining gas exchange and providing antimicrobial as well as pro-immune properties. We previously demonstrated that leukemia inhibitory factor (LIF), an IL-6 family cytokine, is produced by type II alveolar epithelial cells (ATII) and is critical for tissue protection during bacterial pneumonia. However, the target cells and mechanisms of LIF-mediated protection remain unknown. Here, we demonstrate that antibody-induced LIF blockade remodels the lung epithelial transcriptome in association with increased apoptosis. Based on these data, we performed pneumonia studies using a novel mouse model in which LIFR (the unique receptor for LIF) is absent in lung epithelium. Although LIFR is expressed on the surface of epithelial cells, its absence only minimally contributed to tissue protection during pneumonia. Single-cell RNA-sequencing (scRNAseq) was conducted to identify adult murine lung cell types most prominently expressing Lifr, revealing endothelial cells, mesenchymal cells, and ATIIs as major sources of Lifr. Sequencing data indicated that ATII cells were significantly impacted by pneumonia, with additional differences observed in response to LIF neutralization, including but not limited to gene programs related to cell death, injury, and inflammation. Overall, our data suggest that LIF signaling on epithelial cells alters responses in this cell type during pneumonia. However, our results also suggest separate and perhaps more prominent roles of LIFR in other cell types, such as endothelial cells or mesenchymal cells, which provide grounds for future investigation.

Abstract
In bacterial pneumonia, lung damage resulting from epithelial cell injury is a major contributor to the severity of disease and, in some cases, can lead to long-term sequelae, especially in the setting of severe lung injury or acute respiratory distress syndrome. Leukemia inhibitory factor (LIF), a member of the IL-6 cytokine family, is a critical determinant of lung tissue protection during pneumonia, but the cellular sources of LIF and the signaling pathways leading to its production in the infected lung are not known. Here, we demonstrate that lung epithelium, specifically alveolar type II cells, is the predominant site of LIF transcript induction in pneumonic mouse lungs. Epithelial cell cultures were induced to express LIF by bacteria and by sterile bronchoalveolar lavage fluid from pneumonic mice. Reciprocal bone marrow chimera studies demonstrated that LIF deficiency in the nonhematopoietic compartment, but not LIF deficiency in hematopoietic cells, eliminated LIF induction during pneumonia. Although NF-κB RelA (p65) is essential for the expression of many cytokines during pneumonia, its targeted mutation in the lung epithelium was inconsequential for pneumonia-driven LIF induction. However, maximal expression of this epithelial-derived cytokine was dependent on NF-κB RelA in myeloid cells. Overall, our data suggest a signaling axis whereby activation of NF-κB RelA in myeloid cells promotes epithelial LIF induction during lung infections, representing a means through which these two cell types collaborate to improve tissue resilience during pneumonia.

PLoS One 2016; 11:e0147976. [PMID: 26824900 PMCID: PMC4732950 DOI: 10.1371/journal.pone.0147976] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2015] [Accepted: 01/10/2016] [Indexed: 11/30/2022] Open
Abstract
Normal human breathing exhibits complex variability in both respiratory rhythm and volume. Analyzing such nonlinear fluctuations may provide clinically relevant information in patients with complex illnesses such as asthma. We compared the cycle-by-cycle fluctuations of inter-breath interval (IBI) and lung volume (LV) among healthy volunteers and patients with various types of asthma. Continuous respiratory datasets were collected from forty age-matched men including 10 healthy volunteers, 10 patients with controlled atopic asthma, 10 patients with uncontrolled atopic asthma, and 10 patients with uncontrolled non-atopic asthma during 60 min spontaneous breathing. Complexity of breathing pattern was quantified by calculating detrended fluctuation analysis, largest Lyapunov exponents, sample entropy, and cross-sample entropy. The IBI as well as LV fluctuations showed decreased long-range correlation, increased regularity and reduced sensitivity to initial conditions in patients with asthma, particularly in uncontrolled state. Our results also showed a strong synchronization between the IBI and LV in patients with uncontrolled asthma. Receiver operating characteristic (ROC) curve analysis showed that nonlinear analysis of breathing pattern has a diagnostic value in asthma and can be used in differentiating uncontrolled from controlled and non-atopic from atopic asthma. We suggest that complexity analysis of breathing dynamics may represent a novel physiologic marker to facilitate diagnosis and management of patients with asthma. However, future studies are needed to increase the validity of the study and to improve these novel methods for better patient management.
