  • Abstract:

    Radiotherapy (RT) is commonly associated with the treatment of cancer, where it kills or slows down the growth of tumor cells. In addition, it has also been used to successfully treat amyloidosis [1,2], a superfamily of chronic degenerative disorders caused by deposits of toxic protein aggregates in cells and tissues. Recently, low-dose RT (LDRT) has shown positive results on widespread incurable neurodegenerative disorders such as Alzheimer's disease (AD) or Parkinson's disease (PD) [3,4]. The RT modality has been tested with photons, while proton therapy (PT) has so far not been evaluated. The overall aim of this proposal is to analyze the destructive potential of low-dose proton therapy (LDPT) on the accumulation of toxic protein aggregates associated with these neurodegeneration disorders. Monte Carlo (MC) simulations will be confronted with experiments on purified amyloidogenic protein solutions and live-cell models of neurodegenerative disorders. This is to study the effect protons and other types of radiation have on toxic protein aggregates. The results of this multidisciplinary project will lay the groundwork for possible applications of PT on a wide spectrum of neurodegenerative disorders.
