Effect of air pollution on the human immune system

Nature Medicine volume 28, pages 2482–2483 (2022)Cite this article

Subjects

Inhaled particulates from environmental pollutants accumulate in macrophages in lung-associated lymph nodes over years, compromising immune surveillance via direct effects on immune cell function and lymphoid architecture. These findings reveal the importance of improved air quality to preserve immune health against current and emerging pathogens.
