Summary
Pregnancy involves complex immune adaptations, including immune tolerance, to ensure fetal development. Key factors like HLA-G and specific immune cells facilitate maternal acceptance of the semi-allogeneic fetus.
Area of Science:
- Reproductive Immunology
- Maternal-Fetal Medicine
- Immunology
Context:
- Pregnancy requires intricate immune system regulation for successful embryo implantation and fetal development.
- The maternal immune system must accommodate a semi-allogeneic fetus, preventing rejection.
- Understanding these mechanisms is crucial for addressing pregnancy complications.
Purpose:
- To elucidate the immunological mechanisms underlying successful pregnancy.
- To identify key molecular and cellular players involved in maternal-fetal tolerance.
- To explain how the maternal immune system tolerates the fetus.
Summary:
- Pregnancy involves immune cells, Th2 cytokines, and trophoblast molecules for immune tolerance and protection.
- Local factors such as HLA-G, transforming growth factor-beta, and unique uterine natural killer cells are critical.
- Circulating progesterone and glicodeline also regulate the maternal immune response during gestation.
- The fetus is accepted via induced tolerance rather than sensitization, a unique immunological state.
Impact:
- Provides insights into the immunological basis of pregnancy maintenance.
- Highlights the role of specific immune factors in preventing fetal rejection.
- Contributes to understanding reproductive health and potential interventions for pregnancy disorders.

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.
Subsequent T...

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...

Immune Response Against Viral Pathogens
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

Antigens 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.

Cytotoxic T Cells-mediated Immune Response
Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

B Cell Activation and Differentiation
The adaptive immune response, a sophisticated defense mechanism, relies on the activation and differentiation of B lymphocytes, or B cells. These processes enable our bodies to mount a tailored response against specific pathogens such as bacteria, free virus particles, toxins, and parasites.
When naive B cells encounter a specific antigen that can bind to the B cell receptor (BCR) on their surface, they undergo sensitization to respond to the antigen's presence. Sensitization begins with...
