Protein Folding/Misfolding, Amyloids, and Neurodegenerative Diseases

My research focuses on understanding the mechanism of protein misfolding diseases, amyloidosis, by various techniques including biochemical, biophysical, molecular, and cellular methods. Our long-term goal is to elucidate the disease mechanisms of amyloidosis in the aspects of protein folding and structure, pathogenic protein interactions, and relate the results to the medical consequences. We further utilize the knowledge to develop novel diagnostic means and therapeutic modalities. Many ageing-related neurodegenerative diseases such as Alzheimer’s disease (AD) and Parkinson’s disease (PD) belong to amyloidosis. Among them, AD is the most serious problem in the 21st century. Amyloidosis is caused by aggregation of misfolded proteins to form amyloid fibrils comprising specific cross-β structures. Amyloid oligomers that exist in several neurodegenerative diseases imply a common toxicity mechanism in different neurodegenerative diseases. Currently, we are working on three amyloid and amyloid-like proteins and their interacting partners in neurodegenerative diseases. They are amyloid-β (Aβ) peptide and tau protein, the major substance in senile plaques and neurofibrillary tangles of AD patients respectively, α-synuclein, the component of Lewy bodies in PD, and TDP-43, a novel inclusion found in a subtype of frontotemporal lobar dementia (FTLD-U), amyotrophic lateral sclerosis (ALS), and AD. We start from elucidating the mechanism of such aggregation and further developing the diagnostic method, antibodies, and small molecule inhibitors. Moreover, we study the structure, function, and interactions of the related glycan conjugates, precursor proteins, and modifiers. The major research interests are listed as follows:

  • Protein folding and misfolding of amyloids in neurodegenerative diseases.
  • Amyloid protein oligomerization and the toxicity mechanisms in neurodegenerative diseases.
  • Interactions of proteins, glycans, and lipids with the proteins involved in pathogenesis of the neurodegenerative diseases.
  • Drug screening, diagnostic, and therapeutic developments in neurodegenerative diseases.
Amyloid formation, a detrimental protein aggregation, is initiated by protein 
misfolding followed by self-association to ultimately form amyloid fibrils.
The discovery of cytotoxic pre-fibrillar oligomers in many neurodegenerative 
diseases underscores the importance of understanding the folding, aggregation,
and pathogenic mechanisms as well as developing diagnostic and therapeutic

Protein Misfolding and Amyloid-Related Disease Pathogenesis

Our research focuses on understanding the pathogenesis of protein misfolding diseases associated with amyloid deposition using a variety of techniques in biochemistry, biophysics, and molecular cell biology. Amyloid-related diseases are often associated with neurodegenerative disorders, with Alzheimer’s disease being a severe and increasingly prevalent disease in this century, both globally and in Taiwan. Amyloid proteins are formed by misfolded proteins that aggregate to create specific secondary structures, forming fibers. The aggregation of amyloid proteins results in various toxic shapes that harm nerve cells. Interestingly, many amyloid proteins with different primary amino acid sequences share common forms, suggesting shared aggregation mechanisms and associated toxicity.

Our research aims to understand the function and mechanisms of pathogenic protein aggregates, develop detection methods, effective antibodies, and small molecule inhibitors. We also study the impact and interactions of glycation modifications and regulatory factors on amyloid proteins. We hope to provide new directions for early diagnosis and treatment of these neurodegenerative diseases. Currently, our research primarily focuses on the following amyloid proteins and their associated molecules: (1) Amyloid-β and tau proteins in the primary constituents of senile plaques in the brains of Alzheimer’s disease patients, (2) α-synuclein in Lewy bodies in the brains of Parkinson’s disease patients, and (3) TDP-43 protein in the symptoms of frontotemporal dementia/amyotrophic lateral sclerosis. Our main research objectives are as follows:”

  • Protein Folding and Misfolding Mechanisms in Neurodegenerative Diseases
  • Amyloid Protein Oligomers and the Mechanisms of Toxicity in Neurodegenerative Diseases
  • Glycation Modifications of Amyloid Proteins and Their Impact and Interactions with Regulatory Factors
  • Drug Screening, Diagnostic, and Therapeutic Strategies for Neurodegenerative Disease Development
