Research

LBSL research is emerging and geographically diverse. Although first discovered in 2004, meaningful studies of the DARS2 gene—which determines LBSL—were not published until 2012. As a result of our efforts, the first comprehensive LBSL research program performing both clinical and scientific studies was launched at the Kennedy Krieger Institute (KKI) at Johns Hopkins University in 2016. Today, we actively support research into LBSL and the DARS2 gene mutation at four universities. Our organization aims to expand this research to new centers of learning and new patient populations around the globe – connecting researchers, clinicians and patient communities with a goal of generating cohesive collaboration, improving patient outcomes, and advancing cures.

LBSL Research Centers

Kennedy Krieger Institute

Since 2016 the research team at the Moser Center for Leukodystrophies at the Kennedy Krieger Institute in Baltimore, Maryland has made major progress in understanding of the disease process involved in DARS2 gene function and are gearing towards therapeutic targets for LBSL. The team has been working on human observational studies, as well as animal and cell studies testing several therapeutic strategies. The studies utilize wearable technology, neuroimaging, and machine learning methodologies. To summarize, scientists have made several new discoveries and believe that they are on the right path towards identifying therapeutics that they can then push forward towards clinical trials.

Children’s Hospital of Philadelphia

Cure LBSL has joined forces with CureARS to fund a pre-clinical research project with the Mitochondrial Medicine Frontier Program at Children’s Hospital of Philadelphia (CHOP). The aim of this innovative research is to establish and study a full set of animal models for all 19 mitochondrial aminoacyl tRNA synthetase producing genes ("ARS genes" like DARS2 involved in LBSL) and to evaluate potential therapies in these models via high-throughput screening. Drug repurposing involves the study of existing drugs and using them for a medical condition different from what they were originally developed. This strategy offers an expedited and cost saving route to developing new clinical treatments in comparison to traditional drug development. High-throughput screening for this project will examine several thousand already approved FDA drugs and natural product compounds to test their comparative safety and effectiveness.
