Globoid cell leukodystrophy (GLD) is a lysosomal storage disease caused by
deficient activity of ?-galactocerebrosidase (GALC). The infantile forms manifest
with rapid and progressive central and peripheral demyelination, which represent
a major hurdle for any treatment approach. We demonstrate here that neonatal
lentiviral vector-mediated intracerebral gene therapy (IC GT) or transplantation
of GALC-overexpressing neural stem cells (NSC) synergize with bone marrow
transplant (BMT) providing dramatic extension of lifespan and global
clinical-pathological rescue in a relevant GLD murine model. We show that timely
and long-lasting delivery of functional GALC in affected tissues ensured by the
exclusive complementary mode of action of the treatments underlies the
outstanding benefit. In particular, the contribution of neural stem cell
transplantation and IC GT during the early asymptomatic stage of the disease is
instrumental to enhance long-term advantage upon BMT. We clarify the input of
central nervous system, peripheral nervous system and periphery to the disease,
and the relative contribution of treatments to the final therapeutic outcome,
with important implications for treatment strategies to be tried in human
patients. This study gives proof-of-concept of efficacy, tolerability and
clinical relevance of the combined gene/cell therapies proposed here, which may
constitute a feasible and effective therapeutic opportunity for children affected
by GLD.
