Amyloid Fibrils03:03

Amyloid Fibrils

9.6K
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,...

Protein Folding01:25

Protein Folding

8.1K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
Protein Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Alzheimer's Disease: Treatment

212
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Area of Science:

  • Biochemistry and Medicinal Chemistry
  • Pharmacology and Pharmaceutical Sciences
  • Computational Biology

Background:

  • Amyloid fibrillation is a key process in neurodegenerative diseases.
  • Epigallocatechin-3-gallate (EGCG) shows potential as an amyloid inhibitor by degrading fibrils.
  • Optimal dosing strategies for EGCG remain underexplored, hindering clinical application.

Purpose of the Study:

  • To determine the optimal dosage strategy for epigallocatechin-3-gallate (EGCG) in inhibiting amyloid fibrillation.
  • To balance the therapeutic efficacy and potential toxicity of EGCG using optimal control theory.
  • To compare the proposed optimal control strategy with traditional dosing methods.

Main Methods:

  • Utilized a generalized Logistic model for amyloid fibrillation and inhibition.
  • Applied optimal control theory to derive an analytical solution for inhibitor dosing.
  • Systematically compared the optimal control trajectory with traditional drug dosing strategies.
  • Validated findings through experimental comparisons.

Main Results:

  • Derived an analytical solution for the optimal control trajectory of EGCG.
  • Demonstrated that multiple-dose administration is optimal for long-term amyloid disease treatment.
  • Identified single high-dose therapy as preferable for short-term treatment regimens.
  • Showcased the influence of model parameters on the optimal dosing strategy.

Conclusions:

  • The study provides a theoretical framework for optimizing EGCG dosage in amyloid inhibition.
  • Findings suggest tailored dosing strategies (multiple vs. single high-dose) based on treatment duration.
  • This research contributes to the rational clinical application of amyloid inhibitors like EGCG.
