Lung cancer cells activate inflammation to induce metastasis

A research team from the University of California, San Diego School of Medicine has identified a protein produced by cancerous lung epithelial cells that enhances metastasis by stimulating the activity of inflammatory cells. Their findings, to be published in the January 1 issue of the journal Nature, explain how advanced cancer cells usurp components of the host innate immune system to generate an inflammatory microenvironment hospitable for the metastatic spread of lung cancer. The discovery could lead to a therapy to limit metastasis of this most common lethal form of cancer.
