Summary
Serum total IgE levels remained stable throughout pregnancy and postpartum in this study. Further research with larger cohorts and more frequent sampling is recommended for conclusive findings on pregnancy-related IgE changes.
Area of Science:
- Immunology
- Reproductive Health
Background:
- Limited research exists on serum immunoglobulin E (IgE) levels during pregnancy.
- Understanding IgE dynamics is crucial for reproductive immunology.
Purpose of the Study:
- To examine the changes in serum total IgE levels throughout pregnancy and the postpartum period.
- To assess the influence of delivery method and allergy history on these levels.
Main Methods:
- Collected 218 serum samples from 159 pregnant individuals across trimesters and postpartum.
- Analyzed serum total IgE geometric means by trimester, postpartum period, delivery method, and allergy history.
Main Results:
- Serum total IgE showed no statistically significant changes during pregnancy (trimesters 1-3).
- Postpartum IgE levels varied but without statistical significance based on delivery method or allergy history.
- Early postpartum IgE (14.9 IU/ml) was lower than late postpartum (30.3 IU/ml), though not significant.
Conclusions:
- Serum total IgE levels do not significantly change during pregnancy or postpartum in this cohort.
- Findings suggest IgE stability, but larger studies with serial sampling are needed for confirmation.

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...

01:22Development 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.

01:27Ovarian Cycle
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
