Low-Dose Organic Arsenic Exposure Negatively Affects the Immune System in the Lung.

摘要

Arsenic exposure may alter immune response to a common pathogen in the lung, according to a recent study from the Dartmouth College Superfund Research Program (SRP) Center. This study provides insight into how arsenic exposure may increase the risk of respiratory infection and chronic obstructive pulmonary disease, which is associated with chronic bacterial infections and other non-malignant lung infections. The study also helps discern the contribution of organic forms of arsenic alone to the alteration of the innate immune response in the lung.
