Abstract
More than 50 leukodystrophies have been described. This group of inherited disorders affects myelin development and/or maintenance and can manifest from birth to adulthood. Neuroinflammation is a hallmark of some leukodystrophies, explaining in part the therapeutic benefit of hematopoietic stem cell transplantation (HSCT). Indeed, in addition to supplying the CNS with myelomonocyte donor cells expressing the deficient protein or enzyme, HSCT allows the restoration of normal microglia function, which may act on neuroinflammation. In this chapter, we explore the rationale, indication, and outcome of HSCT in Cerebral Adrenoleukodystrophy (CALD), Metachromatic Leukodystrophy (MLD), Krabbe Disease (KD), and Adult-onset Leukoencephalopathy with Axonal Spheroids and Pigmented Glia (ALSP), which are among the most frequent leukodystrophies. For these leukodystrophies, HSCT may modify notably the natural history and improve CNS-related deficits, provided that the procedure is performed early into the disease course. In addition, we discuss the recent development of ex vivo gene therapy for CALD and MLD as a promising alternative to allograft.
期刊介绍：
The Handbook of Clinical Neurology (HCN) was originally conceived and edited by Pierre Vinken and George Bruyn as a prestigious, multivolume reference work that would cover all the disorders encountered by clinicians and researchers engaged in neurology and allied fields. The first series of the Handbook (Volumes 1-44) was published between 1968 and 1982 and was followed by a second series (Volumes 45-78), guided by the same editors, which concluded in 2002. By that time, the Handbook had come to represent one of the largest scientific works ever published. In 2002, Professors Michael J. Aminoff, François Boller, and Dick F. Swaab took on the responsibility of supervising the third (current) series, the first volumes of which published in 2003. They have designed this series to encompass both clinical neurology and also the basic and clinical neurosciences that are its underpinning. Given the enormity and complexity of the accumulating literature, it is almost impossible to keep abreast of developments in the field, thus providing the raison d''être for the series. The series will thus appeal to clinicians and investigators alike, providing to each an added dimension. Now, more than 140 volumes after it began, the Handbook of Clinical Neurology series has an unparalleled reputation for providing the latest information on fundamental research on the operation of the nervous system in health and disease, comprehensive clinical information on neurological and related disorders, and up-to-date treatment protocols.
