Emphysema: An Autoimmune Vascular Disease?

We propose that an endogenous maintenance program controls lung cell turnover, apoptosis, and tissue repair, and that emphysema is a manifestation of the breakdown of the lung structure maintenance program. Emphysema can be induced experimentally in rats by three methods: blockade of vascular endothelial growth factor receptors using SU5416, a small molecule-tyrosine kinase inhibitor; methylprednisolone, which activates matrix...
