Development of Immunocompetence

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 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...

Special Features of Adaptive Immunity

Special 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,...

Maternal-fetal immune tolerance, block by block.

Michael Gobert, Juan J Lafaille

|July 10, 2012

Summary

Inducible regulatory T cells are crucial for maternal-fetal immune tolerance during pregnancy. This discovery sheds light on how the maternal immune system accepts the fetus, preventing rejection.

Area of Science:

Reproductive Immunology
Developmental Biology
Mammalian Placentation

Background:

Pregnancy involves a unique immunological challenge where the mother's immune system must tolerate the semi-allogeneic fetus, which expresses paternal antigens.
The evolution of placentation in eutherian mammals necessitated mechanisms to prevent immune rejection of the developing fetus.

Discussion:

The study investigates the specific immune cells and mechanisms responsible for maintaining maternal-fetal tolerance.
Focuses on the role of regulatory T cells (Tregs) in preventing immune-mediated fetal rejection.
Explores how these regulatory mechanisms are established and maintained throughout gestation.

Key Insights:

Identifies inducible regulatory T cells as key players in establishing and enforcing maternal-fetal immune tolerance.

Demonstrates that these specific T cells actively suppress maternal immune responses against fetal antigens.

Provides a deeper understanding of the cellular basis for successful pregnancy in mammals.

Outlook:

Further research could explore therapeutic applications targeting regulatory T cells to improve pregnancy outcomes in cases of immune-related complications.
Investigating the precise molecular signals that induce these regulatory T cells could reveal new avenues for reproductive health research.
Understanding these mechanisms may offer insights into other transplantation or autoimmune scenarios involving immune tolerance.
