How Air Pollution Alters Lung Tissue, increasing Cancer Susceptibility

Inhaled fine particulate matter (shown here in red) pulls strings of collagen to disturb the immune defence in mice with lung cancer cells. This activity delays the movement of cytotoxic T-cells (purple) as they migrate towards the cancer cells (green) to destroy them. Image credit: Wang et al. 

Scientists have identified a mechanism that explains how fine air pollution particles might cause lung cancer, according to a study published today in eLife.

The findings could lead to new approaches for preventing or treating the initial lung changes that lead to the disease.

Tiny, inhalable fine particulate matter (FPM) found in air pollutants has been recognised as a Group 1 carcinogen and a substantial threat to global health...
