Immunodeficiency Diseases01:25

Immunodeficiency Diseases

2.7K
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...

Cells of the Innate Immune Response

10.1K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

9.3K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.
Natural Killer Cells: The Fast Responders
NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

Differentiation of Common Myeloid Progenitor Cells

4.2K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...

Area of Science:

  • Immunology
  • Genetics
  • Infectious Diseases

Background:

  • Inherited immune deficiencies affecting neutrophil function highlight innate immunity.
  • These disorders increase susceptibility to bacterial and fungal infections with distinct clinical features.

Purpose of the Study:

  • To provide an update on genetic disorders of impaired neutrophil function.
  • To review their pathogenesis and current treatment strategies.

Main Methods:

  • Literature review of genetic disorders affecting neutrophil function.
  • Summary of pathogenesis and clinical manifestations.

Main Results:

  • Chronic granulomatous disease (CGD) involves mutations in nicotinamide dinucleotide phosphate oxidase, affecting superoxide production for pathogen control.
  • Leukocyte adhesion deficiency (LAD) is associated with severe periodontal disease.
  • A novel immune deficiency linked to caspase recruitment domain-containing protein 9 (CARD9) defects causes invasive fungal disease.

Conclusions:

  • Understanding neutrophil function defects is crucial for innate immunity research.
  • Targeted treatments for CGD, LAD, and CARD9-related deficiencies are essential for managing recurrent infections.
