Gaucher disease (GD), an autosomal recessive lysosomal disorder, primarily affects the lysosomal enzyme β-glucocerebrosidase (GCase), leading to glucosylceramide accumulation in lysosomes. GD presents a wide spectrum of clinical manifestations. This study deploys immune-based proteomics and mass spectrometry-based metabolomics technologies to comprehensively investigate the biochemical landscape in 43 deeply phenotyped type 1 GD patients compared to 59 controls.

Gaucher's disease (GD) is a rare autosomal recessive genetic disorder caused by mutations in the gene. Mutations in the gene lead to the deficiency of glucocerebrosidase, an enzyme that helps in the breakdown of glucosylceramide (GlcCer) into ceramide and glucose. The lack of the enzyme causes GlcCer accumulation in macrophages, resulting in various phenotypic characteristics of GD.

Gaucher Disease (GD) is a rare genetic disorder characterized by a deficiency in the enzyme glucocerebrosidase, leading to the accumulation of glucosylceramide in various cells, including red blood cells (RBCs). This accumulation results in altered biomechanical properties and rheological behavior of RBCs, which may play an important role in blood rheology and the development of bone infarcts, avascular necrosis (AVN) and other bone diseases associated with GD. In this study, dissipative particle dynamics (DPD) simulations are employed to investigate the biomechanics and rheology of blood and RBCs in GD under various flow conditions.

The present study reports the preparation of the first multivalent iminosugars built onto a glyco-gold nanoparticle core (glyco-AuNPs) capable of stabilizing or enhancing the activity of the lysosomal enzyme GCase, which is defective in Gaucher disease. An -nonyltrihydroxypiperidine was selected as the bioactive iminosugar unit and further functionalized, via copper-catalyzed alkyne-azide cycloaddition, with a thiol-ending linker that allowed the conjugation to the gold core. These bioactive ligands were obtained with either a linear monomeric or dendritic trimeric arrangement of the iminosugar.

ERT is being administered either in specialized clinics or in the home care setting. Studies indicate that home-based ERT can be considered safe and positively effects patient reported outcomes.
