Yoshinori Ohsumi has won the Nobel Prize in Physiology or Medicine for his work on autophagy, the process by which cells recycle amino acids and other organic compounds. The word means "self eating," which describes how the cell part known as the lysosome uses enzymes to consume and repurpose defunct proteins.
Dr. Ohsumi's research on yeast cells fills in a gap in basic knowledge about cell biology and could lead to insights into neurodegenerative disorders like ALS and Parkinson's disease, as well as Crohn’s disease and other inflammatory syndromes.
