Abstract
Acute lung injury (ALI) manifests through harm to the capillary endothelium and alveolar epithelial cells, arising from a multitude of factors, leading to scattered interstitial alterations, pulmonary edema, and subsequent acute hypoxic respiratory insufficiency. Acute lung injury (ALI), along with its more serious counterpart, acute respiratory distress syndrome (ARDS), carry a fatality rate that hovers around 30-40%. Its principal pathological characteristic lies in the unchecked inflammatory reaction. Currently, the main strategies for treating ALI are alleviation of inflammation and prevention of respiratory failure. Concerning the etiology of ALI, NLRP3 Inflammasome is essential to the body's innate immune response. The composition of this inflammasome complex includes NLRP3, the pyroptosis mediator ASC, and pro-caspase-1. Recent research has reported that the inflammatory response centered on NLRP3 inflammasomes plays a key part in inflammation in ALI, and may hence be a prospective candidate for therapeutic intervention. In the review, we present an overview of the ailment characteristics of acute lung injury along with the constitution and operation of the NLRP3 inflammasome within this framework. We also explore therapeutic strategies targeting the NLRP3 inflammasome to combat acute lung injury.

In utero exposure to electronic-cigarette aerosols decreases lung fibrillar collagen content, increases Newtonian resistance and induces sex-specific molecular signatures in neonatal mice. Toxicol Res 2022; 38:205-224. [PMID: 35415078 PMCID: PMC8960495 DOI: 10.1007/s43188-021-00103-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2021] [Revised: 08/04/2021] [Accepted: 08/25/2021] [Indexed: 12/14/2022] Open
Abstract
Approximately 7% of pregnant women in the United States use electronic-cigarette (e-cig) devices during pregnancy. There is, however, no scientific evidence to support e-cig use as being 'safe' during pregnancy. Little is known about the effects of fetal exposures to e-cig aerosols on lung alveologenesis. In the present study, we tested the hypothesis that in utero exposure to e-cig aerosol impairs lung alveologenesis and pulmonary function in neonates. Pregnant BALB/c mice were exposed 2 h a day for 20 consecutive days during gestation to either filtered air or cinnamon-flavored e-cig aerosol (36 mg/mL of nicotine). Lung tissue was collected in offspring during lung alveologenesis on postnatal day (PND) 5 and PND11. Lung function was measured at PND11. Exposure to e-cig aerosol in utero led to a significant decrease in body weights at birth which was sustained through PND5. At PND5, in utero e-cig exposures dysregulated genes related to Wnt signaling and epigenetic modifications in both females (~ 120 genes) and males (40 genes). These alterations were accompanied by reduced lung fibrillar collagen content at PND5-a time point when collagen content is close to its peak to support alveoli formation. In utero exposure to e-cig aerosol also increased the Newtonian resistance of offspring at PND11, suggesting a narrowing of the conducting airways. At PND11, in females, transcriptomic dysregulation associated with epigenetic alterations was sustained (17 genes), while WNT signaling dysregulation was largely resolved (10 genes). In males, at PND11, the expression of only 4 genes associated with epigenetics was dysregulated, while 16 Wnt related-genes were altered. These data demonstrate that in utero exposures to cinnamon-flavored e-cig aerosols alter lung structure and function and induce sex-specific molecular signatures during lung alveologenesis in neonatal mice. This may reflect epigenetic programming affecting lung disease development later in life.

Abstract
Over-inflammation and severe lung injury are major causes of morbidity and mortality in patients with coronavirus disease 2019 (COVID-19). With the COVID-19 pandemic, an increasing number of patients with preexisting lung injury and inflammation are undergoing surgery or artificial ventilation under sedation in intensive care units, where 2,6-diisopropylphenol (propofol) is a commonly used drug for sedation. The aim of the present study was to investigate whether post-inflammation treatment with propofol protects epithelial type II cells against inflammation in an in vitro model of inflammation. The A549 cell line, characterised as epithelial type II cells, were exposed to lipopolysaccharide (LPS) for 2 h and subsequently treated with different concentrations of propofol (0, 10, 25 or 50 µM) for 3 h. Western blot and reverse transcription-quantitative PCR analyses were used to detect the protein and mRNA expression levels, respectively, of CD14 and Toll-like receptor 4 (TLR4). Immunofluorescence staining was used to detect the in situ CD14 and TLR4 expression in epithelial type II cells. Tumor necrosis factor (TNF)-α production was also examined using ELISA. LPS significantly increased the expression of CD14 and TLR4, as well as the secretion of TNF-α. Post-treatment with 25 and 50 µM propofol of the LPS-treated cells significantly decreased CD14 and TLR4 expression, as well as TNF-α secretion, compared with the cells treated with LPS only, indicating that post-treatment with propofol alleviated inflammation and this effect was dose-dependent. The present study suggested that treatment with propofol after LPS administration has a protective effect on epithelial type II cells.

Abstract
Background Propofol, an intravenous anesthetic, was proven to protect against lung ischemia/reperfusion (I/R) injury. However, the detailed mechanism of Propofol in lung I/R injury is still elusive. This study was designed to explore the therapeutic effects of Propofol, both in vivo and in vitro, on lung I/R injury and the underlying mechanisms related to metastasis-associated lung adenocarcinoma transcript 1 (MALAT1)/microRNA-144 (miR-144)/glycogen synthase kinase-3β (GSK3β). Methods C57BL/6 mice were used to establish a lung I/R injury model while pulmonary microvascular endothelial cells (PMVECs) were constructed as hypoxia/reperfusion (H/R) cellular model, both of which were performed with Propofol treatment. Gain- or loss-of-function approaches were subsequently employed, followed by observation of cell apoptosis in lung tissues and evaluation of proliferative and apoptotic capabilities in H/R cells. Meanwhile, the inflammatory factors, autophagosomes, and autophagy-related proteins were measured. Results Our experimental data revealed that Propofol treatment could decrease the elevated expression of MALAT1 following I/R injury or H/R induction, indicating its protection against lung I/R injury. Additionally, overexpressing MALAT1 or GSK3β promoted the activation of autophagosomes, proinflammatory factor release, and cell apoptosis, suggesting that overexpressing MALAT1 or GSK3β may reverse the protective effects of Propofol against lung I/R injury. MALAT1 was identified to negatively regulate miR-144 to upregulate the GSK3β expression. Conclusion Overall, our study demonstrated that Propofol played a protective role in lung I/R injury by suppressing autophagy and decreasing release of inflammatory factors, with the possible involvement of the MALAT1/miR-144/GSK3β axis.

Abstract
Background Pediatric acute lung injury (ALI) is one of the most common causes of infant mortality. Although lung-protective strategies have developed in recent years, no ALI treatment is currently available. Anisodamine (Ani) is a common drug used to treat gastrointestinal smooth muscle spasm. The protective effects of Ani against acute kidney injury and myocardial injury have been reported. However, the efficacy of Ani on bleomycin (BLM)-induced ALI has not been examined previously. In the present study, we aimed to examine the effects of Ani on bleomycin (BLM)-induced ALI on immature rats. Methods The ALI rat model was established by intratracheally administration of BLM. Ani treatment was performed by an intravenous injection at different concentrations. The lung function of each rat was measured, and then lung tissue structures, apoptosis, and collagen deposition were observed by hematoxylin-eosin staining, terminal deoxynucleotidyl transferase-mediated digoxigenin-dUTP nick-end labeling assay, and Masson’s staining, respectively. Enzyme-linked immunosorbent assay was used to detect the levels of inflammatory cytokines. The expression of apoptosis-related proteins and fibrosis-related markers was determined by reverse transcription-polymerase chain reaction and/or Western blot analysis. Finally, the expression levels of Janus tyrosine kinase 2 (JAK2) and signal transducer and activator of transcription 3 (STAT3) were determined. Results Our findings indicated that lung function was remarkably decreased in BLM-induced rats, which could be reversed by Ani. Ani treatment increased the levels of antioxidant enzymes, decreased the apoptotic rate and apoptosis-related proteins, and downregulated the expression of fibrosis-related markers. Additionally, Ani treatment also attenuated inflammatory response and suppressed the activation of the JAK2/STAT3 pathway. Conclusions Our results demonstrated that Ani had potent activity against BLM-induced ALI in immature rats through inhibiting the JAK2/STAT3 signaling pathway. Our findings provide supporting evidence to further investigate the therapeutic effect of Ani against ALI in children.

Abstract
To investigate the role of miR-128-3p and MAPK14 in the dexmedetomidine treatment of acute lung injury in septic mice. SPF C57BL/6 mice were divided into 8 groups. The pathological changes and wet/dry weight ratio (W/D), PaO2, PaCO2, MDA, SOD and MPO levels in lung tissue and the serum levels of inflammation factors were observed. Dual luciferase reporter assay was used to detect the targeting relationship of miR-128-3p and MAPK14, and qPCR and WB were used to detect the expression of miR-128-3p and MAPK14. Compared with the Normal group, other groups had lower MDA, MPO, inflammatory factors levels and the expression level of MAPK14, while the content of SOD and the expression level of miR-128-3p was significantly decreased (all p < 0.05). Compared with the Model group, the contents of MDA, MPO, inflammatory factors in the DEX group and miR-128-3p mimic group were significantly decreased, and the content SOD was significantly increased, however, opposite results were occurred in oe-MAPK14 group (all p < 0.05). Compared with the DEX group, all the indicators in miR-128-3p mimic+DEX group showed significant improvement (all p < 0.05). Compared with the miR-128-3p mimic group, all the indicators were deteriorated in the miR-128-3p mimic+oe-MAPK14 group (all p < 0.05). The combination of DEX and oe-MAPK14 blocked the protective effect of dexmedetomidine on acute lung injury in septic mice. miR-128-3p can further enhance the protective effect of dexmedetomidine on acute lung injury in septic mice by targeting and inhibiting MAPK14 expression.
