About The Cover

The more basic biology we learn, the more approaches we have for intervention into disease processes. As this special issue on biologically based therapies shows, the knowledge gained from basic investigations of physiology, cell networks, cell biology, and molecular genetics has afforded us opportunities to tap the human body's own processes in promoting health.
