Amyloid Fibrils03:03

Amyloid Fibrils

9.7K
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,...

Long-term Potentiation

55.5K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Summary

Prions are infectious proteins causing neurodegenerative diseases. Researchers suggest long COVID may trigger spontaneous prion emergence, potentially explaining some post-viral symptoms through mitochondrial dysfunction and oxidative stress.

Area of Science:

  • Neuroscience
  • Infectious Diseases
  • Biochemistry

Background:

  • Prions are protein-based infectious agents causing neurodegenerative diseases.
  • Prion disorders involve abnormal protein folding, neuronal loss, and mitochondrial dysfunction.
  • COVID-19 also involves mitochondrial damage and reactive oxygen species production.

Purpose of the Study:

  • To explore the potential link between prion emergence and long COVID symptoms.
  • To investigate the role of mitochondrial dysfunction and oxidative stress in both prion diseases and long COVID.

Main Methods:

  • Comparative analysis of prion disease mechanisms and COVID-19 pathophysiology.
  • Review of existing literature on neurodegenerative diseases and viral infections.
  • Hypothesizing potential molecular pathways connecting SARS-CoV-2 infection to prion-like phenomena.

Main Results:

  • Prion diseases and COVID-19 share mechanistic similarities, including mitochondrial damage and oxidative stress.
  • Behavioral and neurological symptoms observed in both conditions may stem from similar cellular damage.
  • A hypothesis is proposed that long COVID could involve spontaneous prion emergence in susceptible individuals.

Conclusions:

  • Long COVID may be partially explained by the induction of spontaneous prion emergence.
  • Mitochondrial dysfunction and reactive oxygen species are key factors in both prion disorders and long COVID.
  • Further research is warranted to confirm the role of prions in post-acute viral infection syndromes.
