Abstract
Late-infantile neuronal ceroid lipofuscinosis (LINCL) is a recessive genetic disease of childhood caused by deficiencies in the lysosomal protease tripeptidyl peptidase I (TPP1). Disease is characterized by progressive and extensive neuronal death. One hurdle towards development of enzyme replacement therapy is delivery of TPP1 to the brain. In this study, we evaluated the effect of modifying N-linked glycans on recombinant human TPP1 on its pharmacokinetic properties after administration via tail vein injection to a mouse model of LINCL. Unmodified TPP1 exhibited a dose-dependent serum half-life of 12 min (0.12 mg) to 45 min (2 mg). Deglycosylation or modification using sodium metaperiodate oxidation and reduction with sodium borohydride increased the circulatory half-life but did not improve targeting to the brain compared to unmodified TPP1. Analysis of liver, brain, spleen, kidney and lung demonstrated that for all preparations, >95% of the recovered activity was in the liver. Interestingly, administration of a single 2 mg dose (80 mg/kg) of unmodified TPP1 resulted in ∼10% of wild-type activity in brain. This suggests that systemic administration of unmodified recombinant enzyme merits further exploration as a potential therapy for LINCL.

Efficient uptake of recombinant α-galactosidase A produced with a gene-manipulated yeast by Fabry mice kidneys. Mol Med 2012; 18:76-82.

Abstract
To economically produce recombinant human α-galactosidase A (GLA) with a cell culture system that does not require bovine serum, we chose methylotrophic yeast cells with the OCH1 gene, which encodes α-1,6-mannosyltransferase, deleted and over-expressing the Mnn4p (MNN4) gene, which encodes a positive regulator of mannosylphosphate transferase, as a host cell line. The enzyme (yr-hGLA) produced with the gene-manipulated yeast cells has almost the same enzymological parameters as those of the recombinant human GLA produced with cultured human fibroblasts (agalsidase alfa), which is currently used for enzyme replacement therapy for Fabry disease. However, the basic structures of their sugar chains are quite different. yr-hGLA has a high content of phosphorylated N-glycans and is well incorporated into the kidneys, the main target organ in Fabry disease, where it cleaves the accumulated glycosphingolipids. A glycoprotein production system involving this gene-manipulated yeast cell line will be useful for the development of a new enzyme replacement therapy for Fabry disease.

Abstract
To find a new biomarker of Tay-Sachs disease and Sandhoff disease. The lyso-GM2 ganglioside (lyso-GM2) levels in the brain and plasma in Sandhoff mice were measured by means of high performance liquid chromatography and the effect of a modified hexosaminidase (Hex) B exhibiting Hex A-like activity was examined. Then, the lyso-GM2 concentrations in human plasma samples were determined. The lyso-GM2 levels in the brain and plasma in Sandhoff mice were apparently increased compared with those in wild-type mice, and they decreased on intracerebroventricular administration of the modified Hex B. The lyso-GM2 levels in plasma of patients with Tay-Sachs disease and Sandhoff disease were increased, and the increase in lyso-GM2 was associated with a decrease in Hex A activity. Lyso-GM2 is expected to be a potential biomarker of Tay-Sachs disease and Sandhoff disease.

Abstract
In an attempt to investigate whether the genetic defect in the HEXA and HEXB genes (which causes the absence of the lysosomal β-N-acetyl-hexosaminidase), are related to the wide inflammation in GM2 gangliosidoses (Tay-Sachs and Sandhoff disease), we have chosen the dendritic cells (DCs) as a study model. Using the RNA interference approach, we generated an in vitro model of HEXs knock-down immunogenic DCs (i-DCs) from CD34(+)-haemopoietic stem cells (CD34(+)-HSCs), thus mimicking the Tay-Sachs (HEXA-/-) and Sandhoff (HEXB-/-) cells. We showed that the absence of β-N-acetyl-hexosaminidase activity does not alter the differentiation of i-DCs from HSCs, but it is critical for the activation of CD4(+)T cells because knock-down of HEXA or HEXB gene causes a loss of function of i-DCs. Notably, the silencing of the HEXA gene had a stronger immune inhibitory effect, thereby indicating a major involvement of β-N-acetyl-hexosaminidase A isoenzyme within this mechanism.

Abstract
Lysosomal storage disorders are inherited metabolic diseases in which a mutation in a gene encoding a lysosomal enzyme or lysosome-related protein results in the intra-cellular accumulation of substrate and reduced cell/tissue function. Few patients with neurodegenerative lysosomal storage disorders have access to safe and effective treatments although many therapeutic strategies have been or are presently being studied in vivo thanks to the availability of a large number of animal models. This review will describe the comparative advancement of a variety of therapeutic strategies through the 'research pipeline'. Our goal is to provide information for clinicians, researchers and patients/families alike on the leading therapeutic candidates at this point in time, and also to provide information on emerging approaches that may provide a safe and effective treatment in the future. The length of the pipeline represents the significant and sustained effort required to move a novel concept from the laboratory into the clinic.

Abstract
Late infantile neuronal ceroid lipofuscinosis (LINCL) is a progressive neurodegenerative lysosomal storage disorder caused by mutations in TPP1, the gene encoding the lysosomal protease tripeptidyl-peptidase (TPP1). LINCL primarily affects children, is fatal and there is no effective treatment. Administration of recombinant protein has proved effective in treatment of visceral manifestations of other lysosomal storage disorders but to date, only marginal improvement in survival has been obtained for neurological diseases. In this study, we have developed and optimized a large-volume intrathecal administration strategy to deliver therapeutic amounts of TPP1 to the central nervous system (CNS) of a mouse model of LINCL. To determine the efficacy of treatment, we have monitored survival as the primary endpoint and demonstrate that an acute treatment regimen (three consecutive daily doses started at 4 weeks of age) increases median lifespan of the LINCL mice from 16 (vehicle treated) to 23 weeks (enzyme treated). Consistent with the increase in life-span, we also observed significant reversal of pathology and improvement in neurological phenotype. These results provide a strong basis for both clinical investigation of large-volume/high-dose delivery of TPP1 to the brain via the cerebrospinal fluid (CSF) and extension of this approach towards other neurological lysosomal storage diseases.
