Research had already established one way that cells repair leaky lysosomes. Previously, a collection of proteins known as the ESCRT machinery was found to patch up holes in the organelles’ membranes.

Once fats are broken down in the lysosome, they serve several important roles in the cell. One is membrane repair and maintenance. The broken-down fat components, such as phospholipids and ...

The ER, Golgi apparatus, and lysosomes are all members of a network of membranes, but they are not continuous with one another. Therefore, the membrane lipids and proteins that are synthesized in ...
