Cell and gene therapy for Parkinson’s disease - part 1

  1. 1. Cell and gene therapy for Parkinson’s disease Deniz Kirik, MD, PhD Professor of Neuroscience Brain Repair And Imaging in Neural Systems (BRAINS) Unit Department of Experimental Medical Science Lund University, Sweden
  2. 2. Major symptoms of Parkinson’s disease • Difficulty to initiate movement • Slowness of movement • Stiffness • Shaking at rest • Postural imbalance
  3. 3. Parkinson’s disease is characterized by degeneration of dopamine producing cells located in the substantia nigra
  4. 4. Parkinson’s disease is characterized by degeneration of dopamine producing cells located in the substantia nigra
  5. 5. Kirik et al., 2005
  6. 6. Threshold dose of L-DOPA for inducing dyskinesia decreases over duration of the disease 1.8 1.2 L-dopa level (mg/kg) 0.8 0.4 0 Never Stable Wearing-o On-o treated responders (n=8) (n=6) (n=13) (n=12) Mouradian et al. 1987
  7. 7. Restorative treatment strategy for PD No of DA neurons Onset of symptoms Functional recovery Disease progression Restorative therapy
  8. 8. Striatal dopamine replacement strategy by fetal nigral dopamine neurons Parkinson’s Disease Fetal nigral transplantation Input Input Response Response Motor Motor output output
  9. 9. Gene therapy for DOPA delivery Carlsson et al., 2007
  10. 10. Fetal Cell Transplantation Procedure Ventral mesencephalon Transplantation Trypsin/DNase Mechanical dissociation
  11. 11. Fetal Cell Transplantation Procedure Thompson et al., 2005
  12. 12. Transplantation of human fetal DA neuroblasts Mendez et al., 2005
  13. 13. Grafts of fetal dopamine neurons survive and improve motor function in Parkinson's disease Lindvall et al., Science 1990
  14. 14. History of Cell Transplantation in Parkinson's Disease 1979: First reports of functional restoration in rodent models of PD 1990: First report of therapeutic effects in PD patients in open-label trials 2001: Reports of the first placebo-controlled double-blind studies
