Research profile

  • unconventional myosins and actin-binding proteins in cell migration and intracellular trafficking: studies on normal and transformed mammalian cells
  • muscle plasticity and muscle pathology
  • effects of arginine deprivation on cell migration and invasiveness
  • calcium signaling
  • multiple signaling pathways of selected nucleotide receptors
  • role of prion protein in Alzheimer disease and other tauopathies
  • the mechanism of cytotoxicity of the cytosolic form of prion protein.

Current research activities

  • involvement of unconventional myosins (in particular of class VI) in cell migration and intracellular trafficking of organelles and nuclear functions
  • analysis of interaction of myosin VI with its tissue-specific partners
  • understanding mechanisms of limb girdle muscle dystrophy (LGMD): analysis of LGMD patients’ muscle biopsies
  • probing arginine analogs as a component of a potential arginine deprivation-based anti-cancer therapeutical strategy
  • non-calcium signaling from P2X7 nucleotide receptor
  • crosstalk between calcium and small Rho GTPases signaling in glioma cells
  • prion protein in therapy of Alzheimer disease
  • the role of prion protein in amyloidogenesis and neurotoxicity of Tau protein
  • the consequences of the interaction of cytosolic form of prion protein with microtubular cytoskeleton.
