Immunogenetic aspects of preeclampsia
Summary
Preeclampsia (PE) may involve immunogenetic factors. Studies found increased human leucocyte antigen (HLA) sharing between couples and maternal antibodies against partner cells in PE patients, suggesting immune system involvement in this pregnancy disorder.
Area of Science:
- Immunogenetics
- Reproductive Immunology
- Obstetrics
Background:
- The exact cause of preeclampsia (PE) remains unknown.
- Clinical and experimental data suggest a potential role for immunogenetic factors in PE etiology.
- Understanding these factors is crucial for managing this pregnancy disorder.
Purpose of the Study:
- To investigate the role of immunogenetic factors in preeclampsia.
- To analyze human leucocyte antigen (HLA) frequency distribution, antigen sharing, and homozygosity in couples affected by PE.
- To assess maternal antibody production against partner lymphocytes in women with PE.
Main Methods:
- Selected group of 26 women diagnosed with preeclampsia.
- HLA typing and frequency distribution analysis within couples.
- Investigation of HLA antigen sharing and homozygosity.
- Detection of cytotoxic antibodies against partner lymphocytes.
Main Results:
- No significant differences in HLA frequencies or homozygosity were observed between preeclamptic individuals and their partners compared to controls.
- A significantly higher degree of HLA antigen sharing was found between partners in couples with PE compared to couples with normal reproductive history.
- Cytotoxic antibodies against partner lymphocyte surface structures were detected in 46% of women with PE.
Conclusions:
- While HLA frequencies and homozygosity do not appear to be direct factors, increased HLA antigen sharing between partners may play a role in preeclampsia.
- The presence of maternal antibodies against paternal lymphocytes suggests an immune response that could contribute to PE development.
- Further research into the major histocompatibility complex (MHC) and its role in fetal survival is warranted for preeclampsia.

Genomic Imprinting and Inheritance
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

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...

Teratogenicity
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...
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.

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.
