Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

14.6K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

Immunological Memory01:23

Immunological Memory

17.8K
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 Diseases

2.8K
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

1.1K
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...

Antimicrobial Proteins01:23

Antimicrobial Proteins

15.3K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

Area of Science:

  • Immunology
  • Nutritional Science
  • Trace Element Metabolism

Background:

  • The essential trace element zinc plays a crucial role in immune system function.
  • Zinc deficiency is linked to compromised host defense, inflammation, and increased mortality.
  • Maintaining zinc homeostasis is critical for immune cell development and function.

Purpose of the Study:

  • To review the multifaceted roles of zinc in immune cell function.
  • To elucidate the consequences of disrupted zinc homeostasis on the immune system.
  • To highlight the connection between zinc status and immune responses in vivo.

Main Methods:

  • Literature review of existing studies on zinc and immunity.
  • Synthesis of data on zinc's impact on innate and adaptive immune cells.
  • Analysis of molecular mechanisms underlying zinc's immunomodulatory effects.

Main Results:

  • Zinc is essential for the maintenance and development of lymphocytes (T cells, B cells).
  • Disrupted zinc homeostasis impairs lymphocyte formation, activation, and maturation.
  • Zinc influences intercellular communication via cytokines and innate defenses like phagocytosis and oxidative burst.

Conclusions:

  • Zinc is indispensable for proper immune cell function and overall immune competence.
  • Zinc deficiency leads to significant immune dysregulation with potentially severe health outcomes.
  • Understanding zinc's role is key for managing immune-related disorders and infections.
