Lysosomes break down this unwanted matter by enzymes, highly specialized proteins essential for survival. After labs revealed transaminitis, he was referred to gastroenterology. The lysosome is the key cellular hub for macromolecule catabolism, recycling and signalling, and defects that impair any of these functions cause the accumulation of undigested or partially digested macromolecules in lysosomes (that is, storage) or impair the transport of molecules, which can result in cellular damage.
