BMN 250, a fusion of lysosomal alpha-N-acetylglucosaminidase with IGF2, exhibits different patterns of cellular uptake into critical cell types of Sanfilippo syndrome B disease pathogenesis.

PLoS ONE, 2019
Sanfilippo syndrome type B (Sanfilippo B; Mucopolysaccharidosis type IIIB) occurs due to genetic deficiency of lysosomal alpha-N-acetylglucosaminidase (NAGLU) and subsequent lysosomal accumulation of heparan sulfate (HS), which coincides with devastating

Aberrant Glycosylation of IgG in Children With Active Lupus Nephritis Alters Podocyte Metabolism and Causes Podocyte Injury

Arthritis &Rheumatology, EarlyView.
Objective Podocytes are integral to the maintenance of the glomerular filtration barrier. Their injury results in proteinuria and disease progression in lupus nephritis (LN). Aberrant IgG glycosylation drives podocyte injury in LN and leads to cytoskeletal rearrangement, motility changes, and decreased nephrin production.

VPS35 dysfunction impairs lysosomal degradation of α-synuclein and exacerbates neurotoxicity in a Drosophila model of Parkinson's disease

Neurobiology of Disease, 2014
Mutations in vacuolar protein sorting 35 (VPS35) have been linked to familial Parkinson's disease (PD). VPS35, a component of the retromer, mediates the retrograde transport of cargo from the endosome to the trans-Golgi network.

Prorenin-induced myocyte proliferation: no role for intracellular angiotensin II [PDF]

, 2002
Cardiomyocytes bind, internalize, and activate prorenin, the inactive precursor of renin, via a mannose 6-phosphate receptor (M6PR)--dependent mechanism. M6PRs couple directly to G-proteins. To investigate whether prorenin binding to

Assembly of the mannose-6-phosphate receptor into reconstituted clathrin coats. [PDF]

The EMBO Journal, 1985
In ionic conditions in which clathrin coats are stable, the mannose-6-phosphate receptor associates with the 100-kd/50-kd coat complexes purified from bullock brain coated vesicles. These aggregates exist as striking spherical structures of 300-1000 A diameter.

A Surface Plasmon Resonance‐Based Integrated Assay for Quantification and Glycosylation Characterization of Monoclonal Antibodies in Crude Heterogeneous Samples

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The rise in cancer, autoimmune, inflammatory, and infectious diseases in recent decades has led to a surge in the development of monoclonal antibodies (mAbs) therapies, now the most widely used family of biologics. To meet the growing global demand, biopharmaceutical industries are intensifying their production processes.

Genetic Divergence and Antibody Expression Influence the N‐Glycomes of CHO‐K1 and CHO‐S Cells

Biotechnology and Bioengineering, EarlyView.
ABSTRACT While Chinese hamster ovary (CHO) cells continue to be the workhorse of recombinant therapeutic protein production, decades of genetic divergence in the industrially relevant CHO‐K1 and CHO‐S cell lines, are likely to have resulted in differing glycosylation capabilities. Glycosylation can influence the efficacy, serum half‐life, and safety of

Recognition and receptor-mediated endocytosis of the lysosomal acid lipase secreted by cultured human fibroblasts.

Journal of Lipid Research, 1982
We have studied the recognition and uptake of acid lipase by human fibroblasts in order to determine requirements for localization and function of the enzyme in lysosomes.

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

BMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

The GARP Complex Is Involved in Intracellular Cholesterol Transport via Targeting NPC2 to Lysosomes

Cell Reports, 2017
Proper intracellular cholesterol trafficking is critical for cellular function. Two lysosome-resident proteins, NPC1 and NPC2, mediate the egress of low-density lipoprotein-derived cholesterol from lysosomes.
