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...

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...

Summary

This study reveals distinct T-cell immune features in the human placenta. CD3-delta gene expression is higher in the placenta, while CD3-gamma, -epsilon, and -zeta genes are significantly lower compared to umbilical cord blood.

Immunology
Molecular Biology
Human Placental Research

Background:

The human placenta possesses a unique immune microenvironment crucial for pregnancy success.
Understanding T-cell status in the placenta is vital for reproductive immunology.

Purpose of the Study:

To characterize the expression patterns of CD3-gamma, -delta, -epsilon, and -zeta chain genes in the human placenta.
To compare placental T-cell gene expression with that of umbilical cord blood.

Main Methods:

Real-time PCR was used to analyze mRNA expression levels of CD3 gene chains in placental tissue.
Umbilical cord blood (CB) from healthy newborns served as a control.
Beta2-microglobulin gene was used as an endogenous reference for normalization.

Main Results:

Placental expression of CD3-gamma, -epsilon, and -zeta genes was significantly lower than in CB (P<0.0001).
CD3-delta gene expression was stronger in the placenta compared to CB (P=0.895).
The expression order in placenta was delta > zeta > epsilon > gamma, contrasting with CB's epsilon > gamma > zeta > delta.

Conclusions:

The study defines the differential expression profile of CD3 gene chains in the human placenta.
These findings enhance our understanding of placental T-cell immune status and its unique characteristics.
