Patients with rheumatoid arthritis (RA) may experience complications directly from the disease process or from immune-modulating agents used to treat RA. Adalimumab is a recombinant human monoclonal antibody directed against tumor necrosis factor alpha (TNFα) which has been increasingly used in the management of inflammatory and autoimmune diseases. Acute lung injury has been associated with the use of anti-TNFα agents, but the association with adalimumab is rare. Here we present a case of a patient with RA-associated lung disease who developed acute respiratory distress syndrome while being treated with adalimumab. Adalimumab-related lung injury is less common than lung injury associated with other anti-TNFα drugs, thus clinicians should be aware of this condition, as prompt recognition and supportive management can help prevent worsening outcomes.

Functional regeneration of the lung's gas exchange surface following injury requires the coordination of a complex series of cell behaviors within the alveolar niche. Using single-cell transcriptomics combined with lineage tracing of proliferating progenitors, we examined mouse lung regeneration after influenza injury, demonstrating an asynchronously phased response across different cellular compartments. This longitudinal atlas of injury responses has produced a catalog of transient and persistent transcriptional alterations in cells as they transit across axes of differentiation.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) encompass various etiologies and are distinguished by the onset of acute pulmonary inflammation and heightened permeability of the pulmonary vasculature, often leading to substantial morbidity and frequent mortality. There is a scarcity of viable approaches for treating effectively. In recent decades, acupuncture has been proven to be antiinflammatory.

Pulmonary fibrosis (PF) is a lethal pathological change of fibrotic interstitial lung diseases (ILDs) with abundant fibroblasts proliferation after severely or continually alveolar epithelial cells (AECs) injury. Barely therapies are helpful for PF. Here we use bleomycin intratracheally injection to model PF with or without human umbilical cord-mesenchymal stem cells (hUC-MSCs) and/or nintedanib intervention.

Introduction: The factors influencing meconium aspiration syndrome (MAS) severity remain poorly understood. In a piglet model of MAS, we hypothesized the respiratory microbiome would reflect the bacterial signature of meconium with short-chain fatty acid (SCFA) accumulation as a byproduct of bacterial fermentation.
Methods: Cesarean section at approximately 115-day term was performed on two sows.

Bronchopulmonary dysplasia (BPD) is a serious complication in premature infants. This study aimed to investigate the mechanism of mitogen-activated protein 3 kinase 7 (Map3k7) affecting BPD by regulating caspase-1 mediated pyroptosis. The morphology of the lung tissue was observed using hematoxylin-eosin staining.
