Common aspects of immunologic tolerance in pregnancy and malignancy
Obstetrics and Gynecology
|September 1, 1979
Summary
Pregnancy and malignancy share immune tolerance mechanisms. Both conditions involve the immune system tolerating foreign antigenic tissue, suggesting a common underlying process related to embryonic antigens.
Area of Science:
- Immunology
- Reproductive Biology
- Oncology
Background:
- The fetoplacental allograft and malignant neoplasms are unique biological conditions where the immune system tolerates antigenic tissue.
- Both pregnancy and cancer involve complex interactions between the host immune system and foreign or altered self-antigens.
Purpose of the Study:
- To review and identify common immunologic mechanisms shared by pregnancy and malignancy.
- To propose a unifying thesis for the non-rejection of pregnancy and malignancy based on shared antigenic factors.
Main Methods:
- Literature review of tumor immunology and pregnancy immunology.
- Comparative analysis of immunologic mechanisms in both systems.
- Identification of common immunologic denominators.
Main Results:
- Recognition of shared immunologic mechanisms between the maternal-fetal interface and tumor microenvironment.
- Identification of specific immune evasion strategies employed in both pregnancy and cancer.
- Evidence suggesting the role of embryonic antigens in immune tolerance.
Conclusions:
- A common mechanism, potentially involving embryonic antigens, underlies the immune tolerance observed in both pregnancy and malignancy.
- Understanding these shared mechanisms could offer new insights into managing pregnancy complications and cancer treatment.
- Further research into embryonic antigens may reveal novel therapeutic targets for immune-related diseases.

01:40Cell-mediated Immune Responses
Overview
01:15Transcytosis 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...

01:20Special Features of Adaptive Immunity
The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...

01:26Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.

01:22Development 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.

01:27Tumor Immunotherapy
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
