Immortalization of Human Adult Alveolar Epithelial Cells to Study Environmental Exposures of the Distal Lung

Current Protocols, Volume 6, Issue 5, May 2026.
Abstract Alveolar epithelial cell type 1 (AT1) and type 2 (AT2) cells make up the saccular gas exchange units of the lung, called alveoli. Formation of alveoli during lung development accounts for the expansive surface area of the lung, allowing for proper respiration and delivery of oxygen to the body.

The Eubacterium Rectale Derived Extracellular Vesicles Alleviate Cancer Cachexia Induced Lipolysis by Inhibiting Macrophage Polarization

Journal of Extracellular Vesicles, Volume 15, Issue 5, May 2026.
ABSTRACT Cancer cachexia (CC) is a complex pathological condition associated with cancer progression and poor prognosis, particularly in gastrointestinal cancers, and is closely linked to the gut microbiota. Lipolysis in CC may play a key role in driving cachexia progression.
