Pathway-Dependent Inhibition Of Proteopathic Seed Transmission

Tech ID: 28942 / UC Case 2018-028-0


UCLA researchers in the Department of Neurology have developed a novel approach to stop the propagation of proteopathic diseases, which could be applied to wide range of neurodegenerative disorders including Alzheimer’s disease and Parkinson’s disease.


Proteopathy is a common feature of many neurodegenerative disorders, including Alzheimer’s disease and Parkinson’s disease. Alzheimer’s disease market alone is expected to reach over 2.9 billion USD by 2020. Available treatments are largely ineffective, and currently there is no successful approach for modifying the disease to stop its progression. A method to neutralize the spread of proteopathy that contributes to neurodegeneration would revolutionize how we treat proteopathic neurodegenerative disorders.


Researchers at UCLA have developed a novel approach to stop the propagation of proteopathic diseases. Recent data has shown that the proteopathy disease propagation occurs when misfolded or aggregate-prone disease-specific proteins spread to other cells. There, these proteopathic “seeds” serve as a template to cause other proteins to misfold, in a manner similar to that of prions. Researchers in the Department of Neurology at UCLA have identified a specific molecular pathway that can be inhibited to stop proteopathic seed delivery, representing a promising strategy to control progression of neurodegenerative disorders.
