Insights

Protein misfolding, leading to aggregation and diseases like Alzheimer's, remains poorly understood. Cellular quality control failures exacerbate these conformational diseases, often presenting as amyloidoses.

Area of Science:

  • Biochemistry and Molecular Biology
  • Neuroscience
  • Pathology

Background:

  • Protein misfolding is a key factor in various human diseases, particularly neurodegenerative disorders.
  • Over 20 'conformational diseases' are linked to protein misfolding, including Alzheimer's disease (AD), Huntington's disease (HD), and Creutzfeldt Jakob disease (CJD).
  • These conditions are increasingly prevalent in aging populations.

Framework:

  • The fundamental mechanisms driving protein misfolding and subsequent aggregation are not fully elucidated.
  • Cellular quality control systems are crucial for preventing the accumulation of misfolded proteins.
  • Failure of these control mechanisms can lead to profound consequences for cellular and organismal health.

Implementation:

  • Research focuses on understanding the de novo folding process and the stability of correctly folded proteins.
  • Investigating the role of cellular machinery in identifying and eliminating misfolded or aggregated proteins.

Implications:

  • Elucidating these mechanisms is vital for developing therapeutic strategies against debilitating conformational diseases.
  • Understanding protein aggregation pathways can lead to novel diagnostic and preventative measures for neurodegenerative conditions.
  • This research has broad implications for aging populations and public health, addressing the growing burden of amyloid-related diseases.

Amyloid Fibrils03:03

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining, normally used to...

Parkinson Disease ll: Pathophysiology01:24

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
Molecular Chaperones and Protein Folding03:00

Molecular Chaperones and Protein Folding

The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.

The Proteasome01:13

The Proteasome

Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3 (ubiquitin...
