Summary
Immune checkpoint molecules (ICMs) regulate maternal immune tolerance during pregnancy. Targeting these pathways offers potential therapeutic strategies for complicated pregnancies.
Area of Science:
- Immunology
- Reproductive Biology
- Maternal-Fetal Medicine
Background:
- Successful pregnancy requires maternal immune tolerance of the fetus.
- Immune checkpoint molecules (ICMs) like PD-1, CTLA-4, and Tim-3 are crucial for immune regulation during gestation.
- Dysregulation of ICMs is implicated in complicated pregnancies.
Purpose of the Study:
- To review the expression and function of key ICMs at the maternal-fetal interface.
- To explore the role of ICMs in maintaining immune tolerance during pregnancy.
- To discuss the pathogenesis of complicated pregnancies involving immune checkpoints and their therapeutic potential.
Main Methods:
- Review of current literature on immune checkpoint molecules in pregnancy.
- Analysis of ICM expression patterns and functions at the maternal-fetal interface.
- Examination of immune checkpoint pathways in complicated pregnancy pathogenesis.
Main Results:
- ICMs are dynamically regulated at the maternal-fetal interface, crucial for immune tolerance.
- Specific ICMs (PD-1, CTLA-4, Tim-3) play key roles in regulating maternal immune responses.
- Alterations in ICM pathways are associated with the pathogenesis of complicated pregnancies.
Conclusions:
- Understanding ICM regulation is vital for comprehending pregnancy immune dynamics.
- Targeting ICMs presents a promising therapeutic avenue for managing complicated pregnancies.
- Further research into ICMs may unveil novel clinical interventions for gestational complications.

Transcytosis of IgG
2.7K
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...

Development of Immunocompetence
233
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.

Physiological Barriers
3.2K
Physiological barriers are semi-permeable cellular structures restricting drug diffusion into intracellular compartments and tissues. There are six types of physiological barriers: blood endothelial, cell membrane, blood-brain, blood-cerebrospinal fluid (CSF), blood-placenta, and blood-testis barriers.
The blood endothelial barrier is the most porous of these. It allows all small ionized, un-ionized, and lipophilic molecules to pass through the endothelial lining into the interstitial space...
