Background: Volatile anesthetics are gaining recognition for their benefits in long-term sedation of mechanically ventilated patients with bacterial pneumonia and acute respiratory distress syndrome. In addition to their sedative role, they also exhibit anti-bacterial and anti-inflammatory properties, though the mechanisms behind these effects remain only partially understood. In vitro studies examining the prolonged impact of volatile anesthetics on bacterial growth, inflammatory cytokine response, and surfactant proteins - key to maintaining lung homeostasis - are still lacking.

Background: Patients with chronic lung diseases often suffer from pulmonary aspergillosis, caused by Aspergillus fumigatus (AF). Alveolar macrophages play a key role in the initial immune response to AF. Azithromycin (AZM), commonly known for its immunomodulatory properties in reducing exacerbations and improving lung function, has mixed effects on the development of aspergillosis.

The tumor microenvironment (TME) plays a pivotal role in cancer progression, though the molecular regulators governing its immunosuppressive properties remain incompletely characterized. In this study, we identify Makorin-2 (MKRN2) as a novel modulator of TME remodeling through integrated analyses of genetically engineered mouse models and human clinical data. Utilizing MKRN2 knockout mice, we observed significantly accelerated tumor growth compared to wild-type control, which was associated with profound alterations in immune cell composition, especially M2 macrophages.

Sleep deprivation (SD) is a major contributor to cognitive impairment, often accompanied by central neuroinflammation and gut microbiota dysbiosis. The tryptophan (TRP) pathway, activated via indoleamine 2,3-dioxygenase (IDO), serves as a critical link between immune activation and neuronal damage. Umbelliferone (UMB), a naturally occurring coumarin compound, possesses anti-inflammatory, antioxidant, and microbiota-modulating properties.

Acute lung injury (ALI) is characterized by the excessive accumulation of reactive oxygen species (ROS), which triggers a severe inflammatory cascade and the destruction of the alveolar-capillary barrier, leading to respiratory failure and life-threatening outcomes. Considering the limitations and adverse effects associated with current therapeutic interventions, developing effective and safe strategies that target the complex pathophysiological mechanisms of ALI is crucial for improving patient outcomes. Herein, we developed an inhalable, multifunctional nanotherapeutic (MSCNVs@CAT) by encapsulating catalase (CAT) in mesenchymal-stem-cell-derived nanovesicles (MSCNVs).
