[Age and immunity: III. Circulating immune complexes in different age groups (author's transl)]
Summary
Immune complexes, which are indicators of immune system activity, are rarely found in healthy individuals under 60. Their presence significantly increases in older adults, suggesting age-related immune decline.
Area of Science:
- Immunology
- Gerontology
Context:
- Aging is associated with complex changes in the immune system.
- Understanding age-related immune function is crucial for geriatric health.
Purpose:
- To investigate the prevalence of circulating immune complexes (CICs) in healthy individuals across different age groups.
- To explore the relationship between aging and immune system function.
Summary:
- A study analyzed sera from 271 healthy donors using immunofluorescence to detect CICs.
- CICs were virtually absent in individuals under 60.
- Prevalence increased with age: 20% in 60-70 years, 33% in 70-75 years, and 40% in those over 76.
Impact:
- Findings support the hypothesis of age-dependent immunological impairment.
- Increased CICs with age may contribute to age-related autoimmune diseases in the elderly.
- Further research is needed to determine the role of immunological insufficiency in the general aging process.

Overview
Transcytosis of IgG
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Factors Affecting the Risk of Infection
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 create...

Immunological Memory
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 is...

Development of Immunocompetence
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.

Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
