Summary
Folic acid prevents neural tube defects (NTDs), but some women are resistant. Emerging research explores the immune system
Area of Science:
- Immunology
- Developmental Biology
- Public Health
Background:
- Folic acid supplementation significantly reduces neural tube defects (NTDs) incidence globally.
- Despite widespread awareness and food fortification, NTDs remain a major cause of perinatal mortality.
- A subset of women shows resistance to folic acid's protective effects.
Purpose of the Study:
- To review emerging evidence on the immune system's role in NTD development.
- To explore novel preventative strategies for NTD-affected pregnancies.
- To investigate interactions between innate immunity, neurulation, and folate metabolism.
Main Methods:
- Review of clinical and experimental studies.
- Exploration of recent research on innate immune factors.
- Analysis of the complement cascade's role in neurulation and folate metabolism.
Main Results:
- Emerging evidence suggests immune system involvement in NTD etiopathogenesis.
- Novel roles for innate immune factors like the complement cascade are identified.
- Interactions between immune factors, neurulation, and folate metabolism are highlighted.
Conclusions:
- The immune system may play a critical role in NTD development.
- Understanding these immune mechanisms could lead to new preventative strategies.
- Targeting immune pathways may overcome resistance to folic acid supplementation.

01:07Teratogenicity
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...
01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:30Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
01:28Development of the Oral Microbiota
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,...
01:28Biosynthesis of Nucleic Acids
Nucleic acid biosynthesis is a fundamental biochemical process that produces the purine and pyrimidine nucleotides essential for DNA and RNA synthesis. This pathway maintains a balanced nucleotide pool, preventing imbalances that could jeopardize genetic integrity and cellular function. Given the crucial role of nucleotides, their synthesis is tightly regulated to ensure proper cellular homeostasis.Purine BiosynthesisThe biosynthesis of purine nucleotides begins with ribose-5-phosphate, a...
01:29Pharmacogenetic Phenotypes: Alterations in Pharmacokinetics, Drug Targets and Biologic Milieu
Genetic variations significantly influence drug response through pharmacokinetics, receptor interactions, and biologic milieu modifications. Pharmacokinetic alterations impact drug metabolism and clearance, affecting efficacy and toxicity. Variants in drug-metabolizing enzymes, such as CYP2C9 and CYP2C19, alter drug activation and elimination. For example, CYP2C9 loss-of-function variants require lower warfarin doses to prevent excessive bleeding, while CYP2C19 variants reduce clopidogrel...
