Developing Allosteric Chaperones for -Associated Disorders-An Integrated Computational and Experimental Approach.

Mutations in the gene, which encodes the lysosomal enzyme glucocerebrosidase (GCase), are associated with Gaucher disease and increased risk of Parkinson's disease. This study describes the discovery and characterization of novel allosteric pharmacological chaperones for GCase through an innovative computational approach combined with experimental validation. Utilizing virtual screening and structure-activity relationship optimization, researchers identified several compounds that significantly enhance GCase activity and stability across various cellular models, including patient-derived fibroblasts and neuronal cells harboring mutations.

Discovery of allosteric regulators with clinical potential to stabilize alpha-L-iduronidase in mucopolysaccharidosis type I.

Mucopolysaccharidosis type I (MPS I) is an inherited lysosomal disease caused by lowered activity of the enzyme alpha-L-iduronidase (IDUA). Current therapeutic options show limited efficacy and do not treat some important aspects of the disease. Therefore, it may be advantageous to identify strategies that could improve the efficacy of existing treatments.

Validation of a highly sensitive HaloTag-based assay to evaluate the potency of a novel class of allosteric β-Galactosidase correctors.

Site-directed Enzyme Enhancement Therapy (SEE-Tx®) technology is a disease-agnostic drug discovery tool that can be applied to any protein target of interest with a known three-dimensional structure. We used this proprietary technology to identify and characterize the therapeutic potential of structurally targeted allosteric regulators (STARs) of the lysosomal hydrolase β-galactosidase (β-Gal), which is deficient due to gene mutations in galactosidase beta 1 (GLB1)-related lysosomal storage disorders (LSDs). The biochemical HaloTag cleavage assay was used to monitor the delivery of wildtype (WT) β-Gal and four disease-related β-Gal variants (p.

[Epidemiology of multiple sclerosis in Spain].

Introduction: Multiple sclerosis is a chronic autoimmune, inflammatory and neurodegenerative disease of the central nervous system and the most common non-traumatic disabling neurological disease in young adults. In the latest decades, multiple sclerosis is increasing worldwide, especially in women. The latitudinal distribution has been progressively attenuated.

Multiple sclerosis prevalence and incidence in San Vicente del Raspeig, Spain.

Background: Changes in the demographic epidemiology of multiple sclerosis (MS) may challenge the view of a latitudinal gradient in the distribution of MS. The objective of this study was to assess the incidence and prevalence of MS in addition to information on MS phenotypes and the use of disease modifying therapies (DMTs) in San Vicente del Raspeig in south eastern Spain.

Methods: This was a prospective epidemiological study of MS in San Vicente del Raspeig (population of 57,175 inhabitants based on the 2017 census) from 2005 to 2018.
