“Nanotechnology for Managing Alzheimer’s and Other Amyloid Diseases”


Recent advances in nanoscience and technology provide the means to image structures and to measure, monitor and manipulate fundamental biological processes at their native length-scales relevant to normal physiological activity as well as to human diseases. It has provided an important set of visualization and hypothesis-testing tools to the study of the family of neurodegenerative and protein-misfolding diseases, including Alzheimer’s, Huntington’s, Parkinson’s diseases and diabetes among its insidious members. Nanoimaging tools such as the Atomic Force Microscope (AFM) have imaged the three dimensional molecular structures of various amyloids. Amyloids make toxic ion channels that underlie the early key events in the pathology of Alzheimer’s disease (AD) and other degenerative and protein-misfolding diseases. Integrated AFMs with nanopore devices, electrical recording and imaging tools provide simultaneous multidimensional and multiscale functional information. Recently, these nanotools have been used to screen a library of small molecules for controlling the structure-activity relations of these amyloid channels, as potential therapeutics of AD. Delivery of AD therapeutics to the appropriate brain region is equally important for any effective AD management. We are designing controlled, targeted, efficient and safe delivery systems. I will discuss advances in amyloid ion channel paradigm and effective therapeutic strategies.
