Herzenberg wins Kyoto Prize for cell sorter.

Leonard Herzenberg, Ph.D., professor of genetics at Stanford University, received the Kyoto Prize, often called the Japanese version of the Nobel Prize, for developing the fluorescence-activated cell sorter (FACS), the machine that measures patients' CD4 cell counts, and many other cells for research. The same machine can physically sort rare blood cells such as stem cells into a separate compartment, where the living cells can be cultured for research or treatment. The dean of Stanford's School of Medicine called FACS "one of the most important medical devices ever developed."

Dr. Herzenberg received the prize November 10, 2006, at a ceremony in Japan. "I only wish it were possible to be shared with my wife and lifelong colleague, Leonore Herzenberg," he said. Leonore Herzenberg, Ph.D., is also professor of genetics at Stanford. The Kyoto Prize, for contributions to humanity as well as to science, is awarded to one individual in each research team.

The Herzenbergs may be familiar to readers of AIDS Treatment News for their studies of NAC (nacetylcysteine) to restore antioxidant protection by correcting glutathione deficiency in HIV disease. NAC is also being studied in treatment of many other conditions, from bacterial meningitis to cocaine dependency.
