Abstract

Lysosomes are the final destination of the autophagic pathway. It is in the acidic milieu of the lysosomes that autophagic cargo is metabolized and recycled. One would expect that diseases with primary lysosomal defects would be among the first systems in which autophagy would be studied. In reality, this is not the case. Lysosomal storage diseases, a group of more than 60 diverse inherited disorders, have only recently become a focus of autophagic research. Studies of these clinically severe conditions promise not only to clarify pathogenic mechanisms, but also to expand our knowledge of autophagy itself. In this chapter, we will describe the lysosomal storage diseases in which autophagy has been explored, and present the approaches used to evaluate this essential cellular pathway.
