In this project, Dr. Nicholls will begin studies towards an innovative gene therapy strategy for PWS, by developing a single adeno-associated virus (AAV)-vector that incorporates up to 80% of the PWS genes. This project will generate miniaturized components from the PWS genes and build an AAV vector carrying eight PWS genes. Delivery and...
In this project Dr. Lodato will use stem cells from PWS patients to generate human 3D cortical organoids (a ‘minibrain in a dish’). Human cortical organoids are valuable models that mimic aspects of human brain development, and analysis of these organoids is expected to shed light on how brain development in PWS differs from that in typical...
Dr. Reiter’s previous studies suggest that PWS neurons exhibit delayed maturation compared to neurons from typical individuals. Here, his team will use RNA sequencing during neuronal differentiation to better understand the molecular basis of the developmental delay and identify new targets for therapeutic interventions. His team will also...
Prader-Willi (PWS) and Schaaf-Yang syndromes (SYS) are disorders that are both caused by alterations of the MAGEL2 gene, which is either completely missing (PWS) or non-functional (SYS). Working with PWS and SYS mouse models, Dr. Schaaf will investigate the function of a brain ‘support cell’ (astrocytes), which have recently been found to be...
Preliminary research done by Dr. Grzechnik has shown that “long non-coding RNAs”, (lncRNAs) from PWS-region genes may act as important regulators in neurodevelopment. In this project, Dr. Grzechnik will study the changes that occur when the PWS lncRNAs are depleted during the early, middle and late stages of neuronal development.
Dr. Cao has been developing a gene therapy approach that addresses the major symptoms of PWS, through the delivery of a gene that modulates metabolism and behavior (Brain-derived neurotrophic factor, or BDNF). In her 2nd year of funding, her team will assess whether this single-dose viral gene therapy into brain improves metabolism and behavior...
The Foundation for Prader-Willi Research (federal tax id 31-1763110) is a nonprofit corporation with federal tax exempt status as a public charity under section 501(c)(3).
The mission of FPWR is to eliminate the challenges of Prader-Willi syndrome through the advancement of research and therapeutic development.
