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...

Overview of the Reproductive System

Overview of the Reproductive System

The reproductive system generates offspring, ensuring the survival of the species. In humans, the reproductive system is complex and involves a variety of organs and hormones that work together to ensure successful reproduction.
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...

Reproductive Cloning

Reproductive Cloning

Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic cell—any cell that is not a sex...

Diversity of Antigen Receptors

Diversity of Antigen Receptors

Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

Immunological Memory

Immunological Memory

Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...

Summary

This summary is machine-generated.

Pregnancy rejection is avoided by immune tolerance. Immune system dysfunction, particularly in natural killer (NK) cells and T-cells, increases fetal loss and miscarriage risk, especially with anti-HY antigen immunity.

Area of Science:

Immunology
Reproductive Biology
Maternal-Fetal Medicine

Background:

The fetus, semi-allogenic, is typically not rejected by the maternal immune system.
Dysfunctions in innate (NK cells) and adaptive (T-cells) immunity are linked to increased fetal loss.
Pathological pregnancies, like recurrent miscarriages, show exaggerated inflammation and loss of tolerance.

Purpose of the Study:

To investigate the immune system's role in fetal tolerance and pathological pregnancies.
To explore abnormalities in innate and adaptive immunity during pregnancy complications.
To understand the impact of immune interactions at the feto-maternal interface.

Main Methods:

Analysis of immune system components (NK cells, T-cells, regulatory T-cells) in pregnancy.
Investigation of immune responses to autoantigens and fetal antigens.
Examination of interactions between uterine NK cells, trophoblast (HLA-G, HLA-C), and mannose-binding lectin.

Main Results:

Immune system dysfunctions correlate with higher fetal loss rates.
Abnormal innate immune responses, including NK cell interactions, characterize pathological pregnancies.
Pro-inflammatory conditions at the feto-maternal interface may trigger adaptive immunity against fetal alloantigens.
Anti-HY antigen immunity is implicated, particularly in secondary recurrent miscarriage.

Conclusions:

Immune system dysregulation significantly impacts pregnancy outcomes.
Abnormalities in innate immunity, such as NK cell dysfunction, contribute to pathological pregnancies.
Adaptive immune responses against fetal antigens, like HY antigens, are critical in miscarriage etiology.
