title: Endocytosis and lysosomal hydrolysis of proteins in proximal tubules.
abstract: The techniques and basic protocols described above can be readily reproduced by investigators with experience in perfusion of isolated nephron segments. They can be modified and adapted by the investigator to address specific issues. In particular, isolated perfused nephron segments have also been successfully used for elucidation of biochemical and morphological aspects of endocytosis and lysosomal hydrolysis of macromolecules, proteins, and polypeptides. The reader is directed to the references cited under Methodological Approaches in this chapter for a description of these techniques. Although studies on the endocytic uptake and metabolism of proteins and polypeptides using isolated perfused nephron segments have made significant inroads in our understanding of these fascinating and important biological processes, much remains to be learned. Hopefully, future uses of the technique will further advance our knowledge in this field.
