BrainSTORM – PET in Targeted Brain Theranostics and Education
Project period: 2019–2022
Brain theranostics holds tremendous promise for treatment of brain disease, involving design and development of molecular probes for imaging, monitoring and therapy. However, significant challenges remain, such as blood-brain barrier (BBB) permeability, targeted and controlled delivery to specific brain regions as well as early disease diagnosis. The BrainSTORM project aims to address these challenges via multidisciplinary approaches to personalized precision medicine in the areas of Alzheimer ́s disease, depression and brain cancer. The Positron Emission Tomography (PET) Imaging Center in Tromsø opened in 2018 as a state-of-the-art facility for clinical and preclinical PET/CT, PET/MR and SPECT/CT imaging as well as base for the generation of radioactive isotopes and molecules. The co-localization with established UiT research environments in medicine, chemistry, physics, pharmaceutical sciences, biology and science education enable us to develop cutting-edge brain theranostics for personalized precision medicine and an integrated unique educational program. Objectives of the BrainSTORM project include:
Develop PET/SPECT-radiotracers and nanoparticle delivery systems selectively targeting brain receptors central to Alzheimer ́s disease, depression and cancer.
Apply radiotracer systems to cutting-edge theranostics (therapy and diagnostics) and basic brain function studies on animal models.
Advance secondary and tertiary education within interdisciplinary science in health technology and its use in research, treatment and diagnosis of brain diseases.
