Investigators found that instead of fighting tumors, the protein C5a, which is produced during an immune response to a developing tumor, helps tumors build molecular shields against T-cell attack. These findings appeared online this week in Nature Immunology. http://www.physorg.com/news141922882.html Medicine & Health Mon, 29 Sep 2008 16:01:22 EST news141922882
