    STING Inhibits the Reactivation of Dormant Metastasis in Lung Adenocarcinoma

    Researchers used models of indolent lung adenocarcinoma metastasis to identify cancer cell-intrinsic determinants of immune reactivity during exit from dormancy.

    IFNγ Transcribed by IRF1 in CD4+ Effector Memory T Cells Promotes Senescence-Associated Pulmonary Fibrosis

    Investigators determined the mechanism and subtype of aged T cells affecting alveolar type II epithelial cells, which promoted the pathogenesis of senescence-associated pulmonary fibrosis.

    S1PR2 Is Important for Cigarette Smoke-Induced Pyroptosis in Human Bronchial Epithelial Cells

    Researchers investigated the role of sphingosine-1-phosphate receptor 2 (S1PR2) in cigarette smoke extract-induced inflammation and pyroptosis in human bronchial epithelial cells.
    [Archives Of Medical Research]

    Abstract

    Perturbation of Arachidonic Acid and Glycerolipid Metabolism Promoted Particulate Matter-Induced Inflammatory Responses in Human Bronchial Epithelial Cells

    Scientists systematically integrated the metabolomics, lipidomics, and transcriptomics data obtained from the human bronchial epithelial cells exposed to particulate matter to reveal metabolic disorders in particulate matter-induced lung injury.

    Impact of Changes in Human Airway Epithelial Cellular Composition and Differentiation on SARS-CoV-2 Infection Biology

    Air-liquid interface cultures of well-differentiated primary human tracheal and bronchial epithelial cells were employed to study the impact of epithelial cellular composition and differentiation on SARS-CoV-2 infection by transcriptional and immunofluorescent analyses.

    Abstract

    The Dependence of Particle Size on Cell Toxicity for Modern Mining Dust

    Scientists determined whether the size and chemical characteristics of typical coal-mining dust contributed to cellular toxicity. Human macrophages and bronchial tracheal epithelial cells were exposed to mining dust of three sub-micrometer and micrometer size ranges at varying concentrations.

    Depleting DDX1 Sensitizes Non-Small Cell Lung Cancer Cells to Chemotherapy by Attenuating Cancer Stem Cell Traits

    Investigators revealed that DEAD-box helicase 1 (DDX1) was overexpressed in NSCLC cell lines and tissues and further found that depleting DDX1 increased the sensitivity of NSCLC cells to the chemotherapy drug cisplatin, increased cell apoptosis, and inhibited cell migration and invasion.

    Transgelin Promotes Lung Cancer Progression via Activation of Cancer-Associated Fibroblasts with Enhanced IL-6 Release

    Scientists found that transgelin protein levels increased in primary cancer-associated fibroblasts isolated from human lung cancer, compared with those in paired normal fibroblasts.

    Oncogenic Epidermal Growth Factor Receptor Signal-Induced Histone Deacetylation Suppresses Chemokine Gene Expression in Human Lung Adenocarcinoma

    Since the T cell-deserted tumor microenvironment of epidermal growth factor receptor-mutated lung adenocarcinoma (EGFR-mt LA) may lead to the refractoriness of immune checkpoint inhibitors against EGFR-mt LA, researchers investigated the mechanism by focusing on the regulation of chemokine expression.

    Thalidomide Interaction with Inflammation in Idiopathic Pulmonary Fibrosis

    The authors propose that thalidomide can mitigate inflammation in idiopathic pulmonary fibrosis, and can be repurposed either as monotherapy or in combination with nintedanib and pirfenidone.

    Achieve Life Sciences Announces Last Subject Last Visit Completed in Phase III ORCA-3 Trial of Cytisinicline for Smoking Cessation

    The ORCA-3 trial randomized 792 subjects across 20 clinical locations in the United States. Similar to the Phase III ORCA-2 trial, participants received 3mg cytisinicline dosed 3 times daily for either 6 or 12 weeks and were monitored through 24 weeks post-randomization.
