Immunocytochemistry and Immunohistochemistry01:22

Immunocytochemistry and Immunohistochemistry

14.1K
Immunocytochemistry (ICC) and immunohistochemistry (IHC) are techniques that use antibodies to check for specific proteins or antigens in a sample. The technique was first published by Albert Coons in 1941 to detect the presence of pneumococcal antigen in tissue sections from mice infected with Pneumococcus. Immunocytochemistry helps localization of proteins or antigens in individual cells like blood cells, stem cells, etc., while immunohistochemistry does the same for tissue samples.

Inflammatory Bowel Disease II: Crohn's Disease

1.2K
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

2.5K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

Parkinson's Disease: Treatment

1.2K
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Alzheimer's Disease: Treatment

987
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...

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

585
Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

Summary

Prion diseases present diverse phenotypes. Detecting the prion protein (PrP) via immunohistochemistry or biochemistry is key for diagnosing these neurodegenerative conditions, revealing distinct staining patterns.

Area of Science:

  • Neurodegenerative diseases
  • Prion protein research
  • Neuropathology

Context:

  • Prion diseases exhibit a wide range of clinical and neuropathological phenotypes.
  • Definitive diagnosis relies on detecting the prion protein (PrP).

Purpose:

  • To summarize the diagnostic markers and neuropathological findings in prion diseases.
  • To highlight the role of prion protein detection in diagnosis.

Summary:

  • Prion diseases are diagnosed by detecting the prion protein (PrP) using biochemical and immunohistochemical methods.
  • Immunohistochemical analysis reveals three distinct PrP staining patterns: amyloid plaques, perivascular, and diffuse-synaptic.

Impact:

  • Improved understanding of prion disease diagnosis.
  • Foundation for further research into prion protein's role in neurodegeneration.
