Summary: Reproductive immunology focuses on understanding how the maternal immune system supports fetal growth. Maternal uterine natural killer (uNK) cells, in partnership with fetal trophoblast cells, regulate physiological vascular changes in the uterus to build the placenta and sustain fetal growth. The education of uNK cells by maternal MHC-I is crucial for optimal fetal growth.

Summary: Suboptimal nutrition during pregnancy is recognized as a significant modifiable factor in the development of chronic diseases in offspring. The study found that dietary intake of pregnant Indigenous Australian women did not meet national guidelines and that maternal nutrition during pregnancy can impact fetal growth but not fetal kidney growth. Urgent strategies are needed to support and optimize nutrient intake in Indigenous pregnant women.

Summary: Seven years after the Great East Japan Earthquake, researchers investigated telomeres as a potential biomarker of maternal chronic stress in children based on the timing of exposure. They found that children conceived after the disaster had significantly shorter telomeres compared to children who were in utero at the time of the disaster. Telomere length should be further studied as a biomarker for assessing disaster-related trauma.

Summary: This study aimed to investigate the association between maternal serum albumin (MAlb) levels and fetal growth as well as the risk of fetal growth restriction (FGR). The findings revealed a reverse U-shaped relationship between MAlb and fetal growth, indicating an increased risk of FGR when MAlb levels were either too low or too high. These findings are important for understanding the relationship between maternal serum albumin and fetal health.

Summary: This study demonstrates the potential of using EGF-loaded, peptide-decorated liposomes to improve placental function. GPS-decorated liposomes containing EGF significantly increased amino acid transporter activity in healthy placental tissues, but were ineffective in those from pregnancies with FGR. Targeted liposomes represent a safe and useful tool for developing new therapies for placental dysfunction.

Summary: Pregnancy is a vulnerable period for heat exposure, which can lead to placental insufficiency, poor fetal growth, and decreased birth weight. This review examines the evidence linking ambient temperature or heat stress with fetal and placental growth outcomes in humans, ruminants, and murine species, and explores the potential biological pathways involved, particularly focusing on the placenta. The reviewed mechanisms include reduced uterine-placental blood flow, insufficient supply of metabolic substrates to the fetus, activation of the maternal stress-response system, and disruption of endocrine and immune system endpoints. However, research on placenta-mediated pathophysiological mechanisms in humans is limited.

Summary: This study aimed to investigate the temporal changes in testicular gene expression during testes development in fetuses of different size. The results showed that testes weight and testes weight as a percentage of fetal weight were not associated with fetal size at gestational days 60 and 90. Fetal size was not associated with seminiferous tubule area and number, as well as the number of germ or Sertoli cells per tubule. The expression of DMRT1 and SPP1 mRNA was lower in testes associated with the lightest fetuses compared to the closest to mean litter weight fetuses at gestational day 90. These findings provide insights into the expression profiles of genes associated with testicular development and function.

Summary: This study examines dysregulated behaviors using variable-centered and person-centered analyses. The results show that dysregulated behaviors have small and nonsignificant associations with compulsive behaviors, and impulsigenic traits have consistent evidence across various dysregulated behaviors. Person-centered analysis reveals three classes of dysregulated behaviors: high dysregulated behavior, low dysregulated behavior, and aggressive self-harm behavior, with impulsigenic traits and emotion dysregulation influencing the likelihood of classification.

Summary: The study found support for a bifactor model where all indicators load on a common dysregulated behavior factor and unique alcohol, drug, aggression, and self-harm factors. This model provided a better fit to the data than other models. The general dysregulated behavior factor was positively associated with emotion regulation difficulties, negative affect, and BPD symptoms, suggesting implications for psychopathology and intervention research.
