The knowledge of lysosomal biology and the consequences of its dysfunction have increased dramatically in the past 60 years. Research of these disorders has moved from diseases with unknown etiology to disorders with clear and defined pathophysiology and some of them have benefited from the development of disease specific therapeutics. Lysosomal Biology and Storage Disorders describes the nature of the diseases, the historical evolution of the field and future perspectives for the treatment of these clinical entities. Organized as a textbook, Lysosomal Biology and Storage Disorders describes the nature of lysosomal dysfunction, the synthesis and targeting of lysosomal enzymes and the implications of the targeting mechanisms for the development of new therapies. Disease specific chapters provide thorough reviews of the clinical features of lysosomal storage disorders, their molecular basis and the commercial or experimental therapeutic approaches sought in this area.
