Research Projects

Research area
  • New mechanisms of neurodegeneration in poliq model diseases.
  • Characterization of SCA3/MJD KI91 knock-in mouse model.
  • Identification of changes in the level of mRNA and proteins, and modifications (phosphoproteins, ubiquitinated proteins) in different stages of diseases development in the KI91 model.
  • Behavioral characterization of the KI91 mice.
  • Identyfication of new molecular therapeutic targets in poliQ diseases.
  • Therapy of polyQ diseases.
