About CureMILS

Mitochondrial DNA (mtDNA)-associated Leigh syndrome (MILS) is a severe early-onset brain disease affecting 1/100,000 newborns. MILS is typically caused by mtDNA mutations in the ATP-generating subunit MT-ATP6. There are no treatments available for MILS. In fact, drug discovery is particularly challenging for MILS. The limited access to patient neural tissue and the difficulty to manipulate mtDNA hinder the development of transgenic animal models and cellular models, which are needed for treatment discovery and development. Led by Prof. Dr. Alessandro Prigione of the Heinrich Heine University, the CureMILS project aims to employ a novel approach to enable drug discovery of MILS.

Aims

Our consortium will employ neural cells generated from MILS patients via cellular reprogramming to carry out a large-scale screening using marketed drugs, thereby allowing the identification of therapeutic strategies.
Our proof-of-concept study demonstrated that this approach is feasible and relevant. We propose to extend this approach using a large high-quality library of repurposable compounds (more than 5,500). We will validate hit compounds by combining mitochondrial profiling with multi-omics analysis using various reprogramming-derived neural models (neural progenitors, neurons, brain organoids, and blood-brain barrier cells) from different MILS patients.

Objectives

Our consortium will identify drugs suited for repositioning as interventions in MILS, laying the foundation for a multi-national clinical trial and a concrete path towards a cure for MILS.
Moreover, we will establish a paradigmatic working pipeline for reprogramming-driven drug discovery and repositioning for rare neurological disorders.
