Abstract
The prevalence of obesity and its associated comorbidities has surged dramatically in recent decades. Especially concerning is the increased rate of childhood obesity, resulting in diseases traditionally associated only with adulthood. While obesity fundamentally arises from energy imbalance, emerging evidence over the past decade has revealed the involvement of additional factors. Epidemiological and murine studies have provided extensive evidence linking parental obesity to increased offspring weight and subsequent cardiometabolic complications in adulthood. Offspring exposed to an obese environment during conception, pregnancy, and/or lactation often exhibit increased body weight and long-term metabolic health issues, suggesting a transgenerational inheritance of disease susceptibility through epigenetic mechanisms rather than solely classic genetic mutations. In this review, we explore the current understanding of the mechanisms mediating transgenerational and intergenerational transmission of obesity. We delve into recent findings regarding both paternal and maternal obesity, shedding light on the underlying mechanisms and potential sex differences in offspring outcomes. A deeper understanding of the mechanisms behind obesity inheritance holds promise for enhancing clinical management strategies in offspring and breaking the cycle of increased metabolic risk across generations.

Porphyromonas gingivalis outer membrane vesicles shape trophoblast cell metabolism impairing functions associated to adverse pregnancy outcome. J Cell Physiol 2023; 238:2679-2691.

Abstract
Periodontitis is proposed as a risk factor for preterm delivery, fetal growth restriction, and preeclampsia with severe consequences for maternal and neonatal health, but the biological mechanisms involved are elusive. Porphyromonas gingivalis gain access to the placental bed and impair trophoblast cell function, as assessed in murine and human pregnancy, suggesting a pathogenic role in adverse pregnancy and neonatal outcomes. P. gingivalis releases outer membrane vesicles (P. gingivalis OMV) during growth that spread to distant tissues and are internalized in host cells as described in metabolic, neurological, and vascular systemic diseases. Here we tested the hypothesis that P. gingivalis OMV internalized in trophoblast cells disrupt their metabolism leading to trophoblast and placenta dysfunction and adverse pregnancy outcomes. An in vitro design with human trophoblast cells incubated with P. gingivalis OMV was used together with ex vivo and in vivo approaches in pregnant mice treated with P. gingivalis OMV. P. gingivalis OMV modulated human trophoblast cell metabolism by reducing glycolytic pathways and decreasing total reactive oxygen species with sustained mitochondrial activity. Metabolic changes induced by P. gingivalis OMV did not compromise cell viability; instead, it turned trophoblast cells into a metabolic resting state where central functions such as migration and invasion were reduced. The effects of P. gingivalis OMV on human trophoblast cells were corroborated ex vivo in mouse whole placenta and in vivo in pregnant mice: P. gingivalis OMV reduced glycolytic pathways in the placenta and led to lower placental and fetal weight gain in vivo with reduced placental expression of the glucose transporter GLUT1. The present results point to OMV as a key component of P. gingivalis involved in adverse pregnancy outcomes, and even more, unveil a metabolic cue in the deleterious effect of P. gingivalis OMV on trophoblast cells and mouse pregnancy, providing new clues to understand pathogenic mechanisms in pregnancy complications and other systemic diseases.

Abstract
In the last 15 years Zika virus (ZIKV) caused several outbreaks of increasing scale in Micronesia, South Pacific islands, and more recently in the Caribbean and South America. The severity of the clinical presentation in neonates from pregnant women infected with ZIKV during the last outbreak supports the relevance of unraveling the mechanism of infection and viral persistence in the placenta with local viral isolates. Here, we investigated the relevance of trophoblast metabolic rewiring for viral multiplication and the role of the vasoactive intestinal peptide (VIP) as an endogenous factor associated with placental restriction to ZIKV infection at early pregnancy. Our in vitro model demonstrated that ZIKV triggers metabolic rewiring in first trimester cytotrophoblast-derived cells by increasing glucose utilization as fuel to sustain its replication, decreasing long-chain polyunsaturated fatty acid uptake, and promoting lipid droplets accumulation to favor its multiplication. Of note, variations in nutrient availability modulated viral spread in trophoblast cultures. The presence of VIP during trophoblast infection impaired ZIKV infective particle production and viral replication, restoring cell migration and metabolism. Moreover, the blockade of endogenous VIP signaling increased viral particle production and the viral entry receptor AXL expression. These results highlight the potential role of VIP as an endogenous antiviral factor related to trophoblast cell permissiveness to ZIKV infection at early pregnancy.

VPAC1 and VPAC2 receptor deficiencies negatively influence pregnancy outcome through distinct and overlapping modulations of immune, trophoblast and vascular functions. Biochim Biophys Acta Mol Basis Dis 2023; 1869:166593.

Abstract
Pregnancy outcome relies on the maintenance of immune and metabolic homeostasis at the maternal fetal interface. Maternal and perinatal morbidity and mortality is associated with impaired placental development. Multiple regulatory effects of the endogenous-produced vasoactive intestinal peptide (VIP) on vascular, metabolic and immune functions at the maternal-fetal interface have been reported. Here we studied the involvement of the two primary high affinity receptors for VIP (VPAC1 and VPAC2) on maternal immune response, placental homeostasis and pregnancy outcome. Targeted disruption of each receptor gene led to altered placental structure, vascular and trophoblast functional markers and shaped the functional profiles of macrophages and neutrophils towards a proinflammatory state. Several changes in pregnant mice were receptor specific: ROS production elicited by VIP on neutrophils was selectively dependent on the presence of VPAC1 whereas apoptosis rate was associated with the VPAC2 deletion. In peritoneal macrophages from pregnant mice, levels of MHC-II, TLR2, and IL-10 were selectively altered in VPAC2 receptor-deficient mice, whereas IL-6 gene expression was reduced only in mice lacking VPAC1 receptors. Additionally, MMP9 mRNA in isolated TGCs was reduced in VPAC2 receptor deleted mice, while the percentage of IL-12 cells in post-phagocytosis macrophage cultures was selectively reduced in VPAC2 receptor deficient mice. The results indicate that manipulation of VPAC1 and VPAC2 receptor affects immune, vascular and metabolic environment at the maternal fetal interface. These mouse models offer new approaches to study pregnancy complications adding new perspectives to the development of VPAC receptor-selective drugs.

Abstract
Glucose is a primary source of energy used in most organisms. Thus, development of reliable approaches to measure intracellular glucose uptake is an important research issue. 2-[N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl) amino]-2-deoxy-d-glucose (2-NBDG), as a fluorescent glucose derivative, has been widely used to track intracellular glucose uptake by fluorescence imaging and measuring in mammalian cells. However, the avoid-less cross-interference of intrinsic autofluorescence background and tested fluorescent compounds limits its ability to provide trustworthy information on intracellular glucose uptake. By the extraction, separation and detection of 2-NBDG, a simple, sensitive and accurate HPLC-FLD method was established and validated for the measurement of intracellular glucose uptake in HepG2 cells. The developed method has been employed successfully to assess the glucose uptake activity of anti-diabetic drugs and fluorescent natural products. A fit-for-purpose partial validation was further performed for quantification and comparison of glucose uptake in AML12, LO2 hepatocytes, L6 myoblasts and 3T3-L1 preadipocytes.
