Immunological Memory01:23

Immunological Memory

12.3K
Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

3.4K
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...

Development of Immunocompetence01:22

Development of Immunocompetence

1.2K
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Immunocytochemistry and Immunohistochemistry01:22

Immunocytochemistry and Immunohistochemistry

11.3K
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.

Immunofluorescence Microscopy01:12

Immunofluorescence Microscopy

11.1K
A fluorescence microscope uses fluorescent chromophores called fluorochromes, which can absorb energy from a light source and then emit this energy as visible light. Fluorochromes include naturally fluorescent substances (such as chlorophylls) and fluorescent stains that are added to the specimen to create contrast. Dyes such as Texas red and FITC are examples of fluorochromes. Other examples include the nucleic acid dyes 4’,6’-diamidino-2-phenylindole (DAPI), and acridine orange.

Area of Science:

  • Immunology
  • Allergic Diseases
  • Respiratory Medicine

Background:

  • Immune system knowledge is vital for understanding allergic airway diseases.
  • Effective diagnosis and treatment of respiratory allergies depend on immunological insights.

Purpose of the Study:

  • To review the fundamental immunology of the upper airways.
  • To explain the pathophysiology of allergic responses, including allergic rhinitis mechanisms.

Main Methods:

  • Literature review of current immunological understanding.
  • Explanation of innate and adaptive immunity.
  • Description of hypersensitivity reactions and allergic rhinitis.

Main Results:

  • The immune system comprises innate and adaptive immunity.
  • Innate immunity involves physical barriers, phagocytosis, and inflammation.
  • Adaptive immunity is antigen-specific, providing lasting protection; exaggerated responses cause hypersensitivity, like Type I IgE-mediated allergic rhinitis.

Conclusions:

  • Immunomodulatory treatments like immunotherapy exist for allergic airway diseases.
  • A foundational understanding of immune system function is essential for appropriate therapy selection.
