In the lysosomes of our cells its components are processed for reuse. The mechanisms of this process were mostly unknown until the early 1990s, when Yoshinori Ohsumi conducted a series of groundbreaking experiments with yeast, where he detected autophagy and identified genes important for the process. Yoshinori Ohsumi's discoveries laid the foundation for a better understanding of the ability of cells to manage malnutrition and infections, the causes of certain hereditary and neurological diseases, and cancer.
