Two Israelis and an American won the 2004 Nobel Prize for Chemistry on Wednesday for their work related to how the human body singles out unwanted proteins for destruction to defend itself from disease.
Israelis Aaron Ciechanover and Avram Hershko and American Irwin Rose won the 10 million Swedish kronor ($1.36 million) prize for discovering a "kiss of death" marker for proteins, helping explain the immune system, the Royal Swedish Academy of Sciences said.
