What is CDNF? • Conserved Dopamine Neurotrophic Factor • Growth factor known as a trophic factor • Stimulates the growth of neurons
Recent In Vivo Studies • Scientists need rats that exhibit Parkinson’s-like symptoms • Administer 6-Hydroxydopamine (6-OHDA) • Kills off Dopaminergic neurons • Induces Parkinson’s-like symptoms 6-hydroxydopamine L-Dopa Dopamine
Important Lab Findings • CDNF was injected into Striatum of rats before 6-OHDA • CDNF prevented PD symptoms from occurring • Rats were treated to express PD symptoms • Injected with 6-OHDA • 4 weeks later, treated with CDNF • Neuron function and viability was restored
Screening Patients • Adequate patient response to L-Dopa • Indicates DA neurons are degraded but treatable • No effect of L-Dopa • Indicates that DA neurons have degraded completely http://www.physorg.com/news/2010-10-parkinson-disease-closer.html
Benefits in human trials • CDNF has a “protective” effect • Prevents neuron degradation • CDNF can restore up to 98% function • Promoting DNA replication • Can be administered through lumbar puncture • Out-patient procedure • Anaesthetized for comfort • Use Mannitol to penetrate the Blood-Brain-Barrier
