Summary
Galectins, a family of glycan-binding proteins, are crucial for successful mammalian pregnancy. They regulate immune tolerance, implantation, and blood vessel formation at the fetomaternal interface.
Area of Science:
- Immunology
- Developmental Biology
- Reproductive Medicine
Background:
- Successful pregnancy requires maternal immune tolerance of the semi-allogeneic fetus.
- Understanding immune tolerance mechanisms is vital for addressing pregnancy complications.
Purpose of the Study:
- To outline the regulated expression and function of galectins in the fetoplacental unit.
- To elucidate the biological implications of galectins for successful pregnancy.
Main Methods:
- Review of existing literature on galectin function during gestation.
- Analysis of galectin roles in immune cell regulation, implantation, and angiogenesis.
- Integration of galectin functions within maternal-fetal immunological and vascular programs.
Main Results:
- Galectins are key regulators of immune tolerance, including regulatory T cell expansion and tolerogenic dendritic cell promotion.
- Galectins control critical cell adhesion and signaling for implantation.
- Galectins link tissue hypoxia to angiogenesis, essential for placental development.
Conclusions:
- Galectins play a hierarchical and multifaceted role in maintaining successful mammalian pregnancy.
- Targeting galectin pathways may offer therapeutic strategies for pregnancy disorders.

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...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:56Gastrulation
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...
01:27Glucose Transporters
Glucose transporters facilitate the transport of glucose across the cell membrane. In addition to glucose, some glucose transporters can also aid the movement of other hexoses such as fructose, mannose, and galactose.
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

01:38Fertilization
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...
01:14Fetal Circulation
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
