Alveolar macrophages are immune cells that live in the tiny air sacs of the lungs. Under normal conditions, these cells act as guardians, keeping the lungs healthy, supporting breathing, and ...

The immune system remains seriously out-of-whack—in an inflammatory state of overactivation and impaired ...

DENVER — Researchers at National Jewish Health and colleagues have completed the first study comparing lung macrophages in multiple models of lung injury. The research indicates that macrophages ...

A novel iPSC-derived lung-on-chip model mimics human alveolar tissue, revealing macrophage-driven tuberculosis responses.

Microplastics are ubiquitous in the environment, and we all routinely inhale these tiny pollutants. Now new research published at the ATS 2025 International Conference has found that inhaled ...

Researchers at the University of Virginia (UVA) School of Medicine have uncovered a potential path to treatment for persistent COVID-19 symptoms impacting the lungs. The work, published in Science in ...

"The air sacs in the lungs are a critical first barrier against infections in humans, but we've traditionally looked at them ...

Built using pluripotent stem cells, this tiny lung could help push science away from animal testing as well as open the doors ...

Exposure to a common fungal molecule can reprogram immune cells in the lungs, causing them to overreact to infection-like signals and worsen lung damage, according to new research. The study, ...
