Insights

Prion diseases, or Transmissible Spongiform Encephalopathies (TSEs), are transmissible neurological disorders. Research intensifies on transmission routes, susceptibility, and detection of pathological prion protein, especially concerning Bovine Spongiform Encephalopathy (BSE).

Area of Science:

  • Neuroscience
  • Infectious Diseases
  • Biochemistry

Background:

  • Prion diseases are transmissible neurological disorders characterized by protein aggregation.
  • Unlike other neurodegenerative diseases, prion diseases like Creutzfeldt-Jakob disease (CJD) and Bovine Spongiform Encephalopathy (BSE) are transmissible.
  • Historical cases of Scrapie, BSE, and human CJD highlight the long-standing nature of these conditions.

Purpose of the Study:

  • To review current knowledge on prion disease transmission, susceptibility, and molecular mechanisms.
  • To highlight the challenges posed by inapparent prion infections and the need for sensitive detection methods.
  • To summarize new data on BSE transmission and its implications for human health.

Main Methods:

  • Review of existing literature on prion disease transmission and pathogenesis.
  • Analysis of animal models to understand transmission routes and species barriers.
  • Discussion of advancements in diagnostic assay systems for prion detection.

Main Results:

  • Prion diseases are transmissible, with species barriers potentially modulating susceptibility rather than preventing transmission.
  • Inapparent stages of infection can precede overt disease, complicating diagnosis and risk assessment.
  • Bovine Spongiform Encephalopathy (BSE) transmission to humans (variant CJD) is a significant concern, with ongoing investigations into its spread.

Conclusions:

  • Understanding prion transmission, including routes and susceptibility factors, is crucial for public health.
  • Development of highly sensitive assays is essential for early detection of pathological prion protein.
  • Continued research is needed to fully assess the global impact of BSE and prevent further human cases.

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...
Subviral Agents01:29

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
Investigation of Disease Outbreaks01:23

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
Rabies01:28

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
EPS and iPS Cells in Disease Research01:21

EPS and iPS Cells in Disease Research

Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...
Plague01:24

Plague

Plague is a highly virulent zoonotic disease caused by Yersinia pestis, a Gram-negative, facultatively anaerobic coccobacillus. This pathogen primarily circulates among rodent populations and is transmitted to humans through the bite of infected fleas. Additional transmission routes include direct contact with infected animal tissue or inhalation of respiratory droplets from individuals with pneumonic plague. These multiple transmission pathways highlight the bacterium’s potential for rapid...
