Iron in Lung Pathology

The role of iron in pulmonary pathology

Respiratory disease accounts for a large proportion of emergency admissions to hospital and diseaseassociated mortality. Genetic association studies demonstrate a link between iron metabolism and pulmonary disease phenotypes. IREB2 is a gene that produces iron regulatory protein 2 (IRP2), which has a key role in iron homeostasis. This review addresses pathways involved in iron metabolism, parti...

Pathology of lung cancer.

Microscopic examination of stained smears and tissue sections remains the standard method for definitive diagnosis and classification of lung cancer. However, the morphology of lung cancer is complex, and consensus classifications such as those prepared by a panel World Health Organization (WHO) are required for the sake of consistency and clinical relevance. In the most recent (1999) WHO class...

Pathology of lung cancer.

This article reviews current concepts in pathologic classification of lung cancer based on 1999 World Health Organization (WHO)/International Association for the Study of Lung Cancer (IASLC) classification. Preinvasive lesions including squamous dysplasia/carcinoma in situ, atypical adenomatous hyperplasia and diffuse idiopathic pulmonary neuroendocrine cell hyperplasia are discussed in additio...

Iron homeostasis in the lung.

Iron is essential for many aspects of cellular function. However, it also can generate oxygen-based free radicals that result in injury to biological molecules. For this reason, iron acquisition and distribution are tightly regulated. Constant exposure to the atmosphere results in significant exposure of the lungs to catalytically active iron. The lungs have a mechanism for detoxification to pr...
