Researchers are making great strides toward de-veloping gene-based strategies to treat a variety of inherited neurometabolic diseases characterized by severe neurological involvement. A review of the approaches currently under preclinical or clinical investigation is published in Human Gene Therapy.

In the article entitled "Gene-Based Approaches to Inherited Neurometabolic Diseases," coauthors Valentina Poletti and Alessandra Biffi, Dana-Farber/Boston Children's Can-cer and Blood Disorders Center (Boston, MA), and University of Padova (Italy), describe the characteristics needed for a to treat neurometabolic diseases to be suc-cessful. The researchers focus in particular on progress made in the development of gene-based approaches to treat X-linked adrenoleukodystrophy (ALD), metachromatic leu-kodystropy (MLD), mucopolysaccharidoses (MPSs), and neuronal ceroid liposuscinoses (NCLs). They identify microglia as emerging key players in inherited , and therefore as important targets for achieving therapeutic efficacy in gene-based strategies.

"Drs. Poletti and Biffi document some of the dramatic clinical benefits that gene therapy has brought to infants and children with neurometabolic disorders," says Editor-in-Chief Terence R. Flotte, MD, Celia and Isaac Haidak Professor of Medical Education and Dean, Provost, and Executive Deputy Chancellor, University of Massachusetts Medical School, Worcester, MA. "The breakthrough was the insight to use genetic alteration of bone marrow stem cells to cure diseases within the brain, using microglia as the vehicle. This platform has brought hope to many families with previously incurable diseases."
