Amyloid Fibrils

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,...

Subviral Agents

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...

Infection

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Viral Recombination

Viral Recombination

Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Area of Science:

Neuroscience
Infectious Diseases
Molecular Biology

Background:

Prion diseases are fatal neurodegenerative conditions affecting humans and animals.
Prions (PrPSc) are misfolded proteins resistant to disinfection and capable of interspecies transmission.

Purpose of the Study:

To review the current understanding of prion diseases.
To highlight epidemiological and epizootological risks.
To emphasize the need for advanced diagnostic tools.

Main Methods:

Review of molecular genetic studies on prion protein (PrP) conversion.
Analysis of prion resistance to physical and chemical disinfection.
Examination of transmission routes and interspecific barriers.

Main Results:

Normal PrPC proteins convert to infectious PrPSc forms.
Prions exhibit exceptional thermal stability and can overcome species barriers, increasing virulence.
Infection can occur via ingestion of treated meat, surgical interventions, and immunobiological preparations.

Conclusions:

There are no effective treatments for prion diseases globally.
Developing sensitive, preclinical diagnostic tests is vital for national biosafety.
Automated protein amplification and identification methods show promise for prion disease diagnosis.
