Development of Immunocompetence01:22

Development of Immunocompetence

1.1K
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...

Teratogenicity01:07

Teratogenicity

4.5K
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...

Transcytosis of IgG01:15

Transcytosis of IgG

4.5K
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...

Gut-Brain Axis01:22

Gut-Brain Axis

51
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

Development of the Oral Microbiota01:28

Development of the Oral Microbiota

25
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...

Summary

Alcohol consumption during pregnancy harms the developing fetal immune system, increasing newborn infection risks. Improved detection methods are crucial for understanding alcohol

Area of Science:

  • Immunology
  • Developmental Biology
  • Public Health

Background:

  • Prenatal alcohol exposure (PAE) is linked to adverse health outcomes in newborns.
  • PAE may disrupt the fetal immune system, increasing susceptibility to infections.
  • Premature birth, a risk factor for immune issues, is also associated with PAE.

Purpose of the Study:

  • To summarize evidence on alcohol's impact on the fetal immune system.
  • To highlight the need for better methods to identify in utero alcohol exposure.

Main Methods:

  • Review of human and animal research findings.
  • Analysis of indirect effects (e.g., premature birth) and direct effects of alcohol on immune development.

Main Results:

  • Alcohol ingestion during pregnancy can disrupt fetal immune development.
  • This disruption increases the risk of lifelong infections and diseases in newborns.
  • Animal studies confirm direct immune system disruption from alcohol exposure.

Conclusions:

  • Prenatal alcohol exposure poses a significant risk to the developing immune system.
  • Further research is needed, particularly improved methods for identifying PAE.
  • Understanding these mechanisms is vital for preventing long-term health issues in affected children.
