Analysis of transcriptional differences between ZIKV-infected Ifnar-/- and Ifnar+/- placentas

ABSTRACT: Purpose: While type I interferons (IFN) are important for control of viral replication, we see that, upon infection of Ifnar-/- females were crossed to Ifnar+/- males with ZIKV, only Ifnar+/- fetuses are resorbed or develop severe growth restriction. To identify how IFN may be altering placenta development, we performed RNAsequencing on infected and uninfected Ifnar-/- and Ifnar+/- placentas. Methods: Ifnar-/- females were crossed to Ifnar+/- males and infected intravaginally with Cambodian ZIKV at E5.5. Placentas were harvested from infected and uninfected pregnant dams at E10.5. Results/ Conclusions: Comparison of ZIKV-infected Ifnar-/- and Ifnar+/- shows an elevated interferon stimulated gene (ISG) signature in Ifnar+/- placentas but does not reveal any underlying developmental defects that may be causing defects in placenta development.

Proteomic profiles of ZIKV-positive placentas of fetuses with microcephaly

Project description:Here we use a proteomic approach to study the role of the placenta in ZIKV-induced microcephaly and the mechanisms of ZIKV to cross the placental barrier. Samples were separated into three groups: an uninfected control group (ZIKV-CZS-), a group of placentas infected by ZIKV with normal neonates (ZIKV+CZS-), and a group of placentas infected by ZIKV that developed microcephaly in newborns (ZIKV+CZS+). Zika virus causes DNA damage and impairs gene expression and mRNA translation during infection of the placenta. Processes related to viral transcytosis, like endocytosis, autophagy and disruption of actin filament were also observed in CZS-infected placentas, which could lead to a higher virus infiltration. Unncontrolled maternal immune response as well as greater expression of cellular adhesion proteins in the decidua could lead to a disruption of tolerance during pregnancy and induction of neurological malformation of the neonates

Decreased CSTB, RAGE and Axl receptor is associated with Zika infection in the human placenta

Project description:Zika virus (ZIKV) compromises the placental integrity infecting the fetus. However, the mechanisms associated with ZIKV penetration into the placenta leading to fetal infection, are unknown. Cystatin B (CSTB), the receptor for advanced glycation end products (RAGE), and tyrosine-protein kinase receptor UFO (AXL) have been implicated in inflammation. The purpose of this work iis work aims to investigate CSTB, RAGE, and AXL receptor expression in ZIKV infected placental tissues at term. The hypothesis is that in ZIKV-infected placenta, there is overexpression of CSTB and increased inflammation affecting the RAGE and AXL receptor expression. Pathological analyses of 22 placentas were performed to determine changes caused by ZIKV infection. Quantitative proteomics, immunofluorescence, and Western Blot analysis were performed to analyze proteins and pathways affected by ZIKV infection in frozen placenta. Pathological The pathological analysis confirmed decreased size of capillaries, hyperplasia of Hofbauer cells, disruption in the trophoblasts layer, and cell agglutination associated to with ZIKV infection of placental tissue. ZIKV infection was mostly localized to the trophoblast layer. There was a significant decrease in the expression of CSTB, RAGE and AXLCSTB, RAGE and AXL expression in ZIKV positive placenta. This downregulation can impair immune responses and facilitate virus penetration into the placenta. Results are consistent with our previous studies and literature of on ZIKV infection by activation ofng Inflammasome and Pyroptosis through caspase 1 upregulation and affecting the cellular structure, tissue remodeling, and cell differentiation by upregulation of tubulin beta and heat shock protein 27.

Targeted_PRM_Urine_Carnitine_Efficacy_Study_Males_Females

Project description:5-week old male and female Swiss Webster mice were infected with 500,000 Trypanosoma cruzi strain Sylvio X/104 parasites. Urine was collected from uninfected mice pre-infection, from infected and uninfected mice every week for 5 weeks post infection, from infected and uninfected mice 67 (females)/68 (males) days post infection, and from infected and uninfected mice 117 (females)/124 (males) days post infection for acute, mid-chronic, and chronic time-points. Metabolites were extracted with methanol and a targeted PRM LCMS analysis was ran on a Thermo Q Exactive Plus instrument with a Phenomenex Luna Omega Polar C18 column.

Sex differences during acute myocarditis against coxsackievirus B3 (CVB3)-induced myocarditis (10 dpi) and chronic myocarditis/dilated cardiomyopathy (DCM) against CVB3-induced myocarditis (90 dpi)

Project description:Men are at an increased risk of dying from heart failure caused by inflammatory heart diseases such as atherosclerosis, myocarditis and dilated cardiomyopathy (DCM). We previously showed that immune responses in the heart are phenotypically distinct in male compared to female mice 10 days after infection resulting in severe DCM in males. Groups consisted of Infected Males, Infected Females, Uninfected Males and Uninfected females. There are 3 mice per group. A total of 12 samples were analyzed in this experiment (12 for 10 dpi and 12 for 90 dpi).

Sex-Specific DNA Methylation and Gene Expression Changes in Mouse Placentas After Early Preimplantation Alcohol Exposure[RNA-Seq]

Project description:Preimplantation alcohol exposure can negatively impact embryonic development through disruption of molecular profiles and lead to fetal alcohol spectrum disorder (FASD). Despite the central role of the placenta in proper embryonic development and successful pregnancy, studies on the placenta in a FASD context are markedly lacking. Here, preimplantation binge-like alcohol exposure was implemented on pregnant C57BL/6 female mice through subcutaneous injection with two doses of either 2.5 g/kg 50% ethanol or an equivalent volume of saline at 2-h intervals on embryonic day 2.5 corresponding to the 8-cell stage. The placental morphology, DNA methylation and gene expression patterns in male and female late-gestation (E18.5) placentas were assessed. While overall placental morphology was not affected, we found a significant decrease in male ethanol-exposed embryo weights. When looking at molecular profiles, we uncovered numerous differentially methylated regions (DMRs ≥10% difference; 991 in males; 1309 in females) and differentially expressed genes (DEGs; 1046 in males; 340 in females) in the placentas. Remarkably, only 21 DMRs and 54 DEGs were common to both sexes, which were enriched for genes involved in growth factor response pathways. Preimplantation alcohol exposure had a greater impact on imprinted genes expression in male placentas (imprinted DEGs: 18 in males; 1 in females). Finally, by using L1-regularized linear regression, we were able to precisely discriminate control and ethanol-exposed placentas based on their specific DNA methylation patterns. This is the first study demonstrating that preimplantation alcohol exposure alters the DNA methylation and transcriptomic profiles of late-gestation placentas in a sex-specific manner. Importantly, it reveals a placental DNA methylation signature that can detect prenatal alcohol exposure in early life in order to provide appropriate support to attenuate and prevent eventual impact.
