Imaging of acute dissemination of tuberculosis caused by alveolar lavage surgery in endobronchial tuberculosis characterized by caseous necrosis

Respirology Case Reports
Large amount of caseating overlying on bronchus were detected under bronchoscopy in our case. Bronchoalveolar lavage is a major method for diagnosing tuberculosis (TB). TB dissemination caused by bronchoalveolar lavage is very rare.

Inhaled Angiopoietin‐Like 4 Antisense Oligonucleotide Therapy for Lung Injury and Fibrosis

Advanced Science, EarlyView.
Inhaled antisense oligonucleotides targeting ANGPTL4 attenuate inflammation, preserve barrier integrity, and reduce fibrosis in both infectious and sterile lung injury models. Integrated transcriptomic analysis reveals a conserved ANGPTL4‐regulated gene network coordinating hypoxic, inflammatory, apoptotic, and stress‐response pathways.

Attenuation of Influenza a Virus into Live Vaccines Through C‐End Degrons

Advanced Science, EarlyView.
Naturally occurring C‐end degrons are exploited to design proteolysis‐targeting live attenuated influenza vaccines. C‐end degron tagging of viral M1 protein promotes proteasome‐dependent degradation, resulting in robust attenuation in host cells while permitting scalable production in engineered cells.

Endogenous “Time Bomb” – Mislocalized Phospholipase A2 as a Critical Mediator of Ultra‐Rapid Mortality in Sepsis and Acute Lung Injury

Advanced Science, EarlyView.
Phospholipase A2 (PLA2), a dormant enzyme, becomes lethal when activated—collapsing lungs in minutes. Our dual therapy (DOPS + varespladib) boosts survival from 0% to >90% in sepsis/ALI. A breakthrough for acute lung injury treatment. ABSTRACT This study reveals that phospholipase A2 (PLA2), normally stable and nontoxic, can be activated specifically ...

Androgens augment pulmonary responses to ozone in mice

Physiological Reports, 2019
Ozone causes airway hyperresponsiveness, a defining feature of asthma, and is an asthma trigger. In mice, ozone‐induced airway hyperresponsiveness is greater in males than in females, suggesting a role for sex hormones in the response to ozone.

Bronchoalveolar Lavage and Lung Tissue Digestion

Bio-Protocol, 2013
Bronchoalveolar lavage (BAL) is a simple but valuable and typically performed technique commonly used for studying the pathogenesis of lung diseases such as asthma and COPD.

Targeting the GPX4–FUNDC1 Interaction with Magnesium Lithospermate B Attenuates Sepsis‐Associated Lung Injury

Advanced Science, EarlyView.
The diagram depicts the endothelial‐protective mechanism of magnesium lithospermate B (MLB) in sepsis‐associated lung injury. MLB binds GPX4 at Gly79, disrupts its interaction with FUNDC1, prevents mitophagy‐mediated GPX4 degradation, restores mitophagic flux, reduces ROS, and limits ferroptosis.

Clinical evaluation of the Simplexa HSV 1 & 2 Direct assay for bronchoalveolar lavage specimens

Journal of Clinical Virology Plus
Rapid laboratory testing is essential to detect HSV in the lower respiratory tract to allow rapid treatment decisions. We evaluated the clinical performance of the Simplexa HSV 1 & 2 Direct assay in bronchoalveolar lavage.

Macrophage TRIM21 Inhibition Ameliorates Murine Acute Pancreatitis via PHB2‐Mediated Mitochondrial Stabilization

Advanced Science, EarlyView.
Macrophage‐derived TRIM21 drives the progression of AP via ubiquitin‐proteasome‐mediated degradation of PHB2, leading to impaired PHB2‐mediated mitophagy. Therefore, accumulation of cytosolic mtDNA hyperactivates the cGAS‐STING signaling axis, thereby amplifying inflammatory cascades.
