Introduction to Innate and Adaptive Immunity

8.5K
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Development of Immunocompetence

771
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...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

1.9K
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...

Area of Science:

  • Immunology
  • Molecular Genetics

Background:

  • Primary immunodeficiencies (PIDs) are a group of genetic disorders affecting the immune system.
  • Advances in molecular genetics and immunology have led to the identification of numerous PID-causing genes and a deeper understanding of their pathophysiology.

Purpose of the Study:

  • To review recent advances in the pathogenesis, diagnosis, and treatment of primary immunodeficiencies.
  • To highlight novel diagnostic assays and therapeutic strategies for PIDs.

Main Methods:

  • Review of recent literature on primary immunodeficiencies.
  • Analysis of molecular mechanisms, diagnostic approaches, and treatment modalities.

Main Results:

  • Identification of a growing number of PID-causing genes.
  • Development of novel diagnostic assays based on protein expression analysis.
  • Initiation of newborn screening programs for severe combined immunodeficiency.
  • Significant progress in PID treatment, including subcutaneous immunoglobulins, hematopoietic cell transplantation, and gene therapy.

Conclusions:

  • Recent advances have significantly improved the understanding and management of primary immunodeficiencies.
  • Novel diagnostic and therapeutic strategies offer improved outcomes for patients with PIDs.
