Prion Safety Laboratory Swipe Test06:01

Prion Safety Laboratory Swipe Test

1.3K
A method to assess commonly used areas in laboratory settings for prion contamination and effective decontamination is lacking. The protocol described here provides key fundamentals for implementing a laboratory prion safety swipe test that can easily be modified to meet the individual needs of specific...

X-Inactivation

41.6K
The human X chromosome contains over ten times the number of genes as in the Y chromosome. Since males have only one X chromosome, and females have two, one might expect females to produce twice as many of the proteins, with undesirable results.

Detection of Abnormal Prion Protein by Immunohistochemistry

3.7K
Immunolabeling abnormal prion protein using immunohistochemistry protocols requires specific sample and anti-PrP antibody preparation methodologies. The present protocol describes the key steps in epitope demasking to ensure proper PrP immunolabeling and to minimize non-specific background staining. Also, this approach considers biosafety measures when conducting immunohistochemistry studies with the prion-infected...

This video demonstrates a technique to detect misfolded prion protein in brain sections using immunohistochemistry. Upon treating the brain section with formic acid to denature prions and minimize infection risk, as well as unmasking the prion aggregates using heat-induced epitope retrieval, the sections are immunolabeled for the misfolded prion protein aggregates and observed under a...

Adipose-Derived Mesenchymal Stromal Cells Co-Cultured with Primary Mixed Glia to Reduce Prion-Induced Inflammation

815
Adipose-derived mesenchymal stromal cells (AdMSCs) have potent immunomodulatory properties useful for treating diseases associated with inflammation. We demonstrate how to isolate and culture murine AdMSCs and primary mixed glia, stimulate AdMSCs to upregulate anti-inflammatory genes and growth factors, assess migration of AdMSCs, and co-culture AdMSCs with primary mixed prion-infected glia.

Summary

Iatrogenic Creutzfeldt-Jakob disease (iCJD) transmission risks from contaminated medical devices necessitate validated prion inactivation methods. This chapter details practical approaches for effectively decontaminating surgical instruments.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Medical Device Sterilization

Background:

  • Iatrogenic Creutzfeldt-Jakob disease (iCJD) can result from prion contamination via transplanted tissues or reused medical devices.
  • Prions are highly resistant to conventional sterilization, posing a significant risk in neurosurgery and other procedures.
  • The reuse of surgical instruments after procedures on patients with prion diseases requires stringent decontamination protocols.

Purpose of the Study:

  • To introduce fundamental aspects of prion inactivation methods.
  • To address practical implementation challenges for prion decontamination in healthcare settings.
  • To emphasize the necessity of scientifically proven methods for medical device safety.

Main Methods:

  • Review of scientifically validated prion inactivation techniques.
