Sepsis-induced acute lung injury (ALI) is a common acute and severe reason of death in the intensive care unit. Although the pathogenesis is complicated and multifactorial, elevated inflammation and oxidative stress are considered as fundamental mechanisms for the progression of ALI. Anemonin is a natural compound with diverse biological properties including anti-inflammatory and anti-oxidative effects.

The inflammatory response mediated by alveolar macrophages plays a crucial role in the development of acute lung injury. Numerous studies have reported that lncRNAs are highly expressed in acute lung injury in mouse models and cell lines, and acute lung injury (ALI) can be effectively alleviated by targeting these lncRNAs. The aim of this study was to explore the mechanism by LncRNA Gm26917 regulates the inflammatory response in alveolar macrophages during acute lung injury mouse model.

Polystyrene nanoplastics (PS-NPs) are omnipresent in the air and can be inhaled by humans. However, their long-term adverse implications and toxicological mechanisms for human respiratory health are unclear. Therefore, this study aims to provide new insights into the pulmonary toxicity of PS-NPs using mice and organoid models.

Acute respiratory distress syndrome (ARDS) is featured with acute lung inflammatory injury. Our prospective study found that higher levels of peroxiredoxin 6(PRDX6) were detected in bronchoalveolar lavage (BAL) fluid from ARDS patients. Elevated PRDX6 was also correlated with monocytic activation and poor prognosis in ARDS patients.

The limitations of existing mouse models of lung infection with Mycobacteroides abscessus impede drug discovery and development. In contrast to current animal models that introduce NTM intravenously or by intranasal/intra-tracheal instillation or via bronchoscopy-guided insufflation, we developed a dry powder inhalation (DPI) of M. abscessus ATCC 19977 that generated paucibacillary lung infection and histopathology in immunocompetent mice.
