Analysis of transcriptional differences after IFN-beta (IFN-b) or IFN-lambda (IFN-l) treated human mid-gestation chorionic villus explants

ABSTRACT: Purpose: Treatment of midgestation chorionic villus explants with recombinant IFN-b leads to morphological changes including formation of syncitial knots. However, treatment of explants with IFN-l, which is constitutively expressed by syncytiotrophoblasts, is not sufficient to cause these same changes. To understand the different transcriptional changes induced by IFN-b and IFN-l and underlying cause of these morphological changes, we performed RNAsequencing after these different treatments. Methods: Chorionic villi of 18-21 gestation week placentas were dissected. Explants were cultured in DMEM F/12 with 1000 U recombinant IFN-b or 1000U recombinant IFN-l for 24 hours. RNA was then isolated from explants, and RNAsequencing was performed to assess transcriptional changes. Results/ Conclusions: IFN-b but not IFN-l induces interferon stimulated genes (ISGs) in mid gestation chorionic villus explants.

High Rates of Placental Inflammation in Samples Collected by the MOMI Consortium

Project description:OBJECTIVES: The Multi-Omics for Mothers and Infants (MOMI) consortium aims to improve birth outcomes. We analyzed full thickness placental samples (e.g., basal plate, placenta/chorionic villi and the chorionic plate) collected by the 5 MOMI sites: The Alliance for Maternal and Newborn Health Improvement (AMANHI) Bangladesh, AMANHI Pakistan, AMANHI Tanzania, The Global Alliance to Prevent Prematurity and Stillbirth (GAPPS) Bangladesh and GAPPS Zambia. STUDY DESIGN. The teams collected biopsies from 294 preterm (gestation <37 weeks) and 291 term (gestation ≥37 weeks) births. They were formalin-fixed and paraffin embedded. Tissue sections from these samples were stained with hematoxylin and eosin and subjected to morphological analyses. Other placental biopsies (n = 35 preterm, 21 term) were collected in RNAlater, which enabled bulk transcriptomics. RESULTS. The morphological analyses revealed a surprisingly high rate of inflammation involving the basal plate, placenta/chorionic villi and the chorionic plate. The rate in chorionic villus samples ranged from 25% (Pakistan site) to 60% (Zambia site) of cases. Leukocyte infiltration in this location vs. the basal plate or chorion plate correlated with preterm birth. The transcriptomic analyses identified 267 genes as differentially expressed (DE) between placentas from preterm vs. term births (123 upregulated, 144 downregulated). Mapping the DE genes onto single cell RNA-seq data from human placentas suggested that all the component cell types, either singly or in subsets, contributed to the observed dysregulation. Consistent with the histopathological findings, (Gene Ontology) GO analyses highlighted leukocyte infiltration/activation and inflammatory responses in both the fetal and maternal compartments. CONCLUSION. Together these data suggested geographic- and/or population-based differences in placental inflammation and the triggers of preterm birth.

Human IFN-λ3 and IFN-λ4 show distinct molecular phenotypes in macrophages

Project description:CD14+ cells were used to obtain M1 or M2-MDMs in presence of recombinant human IFN-λ3 or IFN-λ4. Briefly, four Caucasian donors (n=4; one female and three males) in between 31-41 y of age, were used to obtain highly homogenous CD14+ cells; these were purchased from a commercial source. The CD14+ cells were incubated with GM-CSF (for M1-MDM) or M-CSF (for M2-MDM) in presence or absence of IFN-λ3 (at 50 ng/ml) or IFN-λ4 (at 6 μg/ml) for six days, and then the cells were fully washed off any residual growth factors or IFNs. After six days of differentiation, the macrophages were matured with LPS for 24 h, then the total cellular RNA was isolated and RNA-seq was performed at QuickBiology, Psadena, CA, USA Summary of the study: Type III interferons or IFN-λs have emerging roles beyond antiviral defense at barrier surfaces. IFN-λ3 and IFN-λ4 are genetically associated with several infectious and inflammatory diseases; however, strong linkage at the IFNL locus circumvents a clearer understanding of their differential influence on the disease phenotypes. Comparative studies to examine the effect of IFN-λ3 and IFN-λ4 on immune cells are lacking. In this study, we used human CD14+ monocytes differentiated into macrophages (MDMs) in presence of IFN-λ3 or IFN-λ4 under M1 or M2 conditions, and after maturation with lipopolysaccharides, to perform RNA-seq analysis in order to understand the changes in molecular phenotypes that may have been induced by the two IFN-λs. Firstly, we found that IFN-λ4 can induce several genes, both unique and common to those induced by IFN-λ3, especially in M1-MDMs; our analysis showed that close to 870 genes (in both cell types) were reciprocally regulated by IFN-λ3 and IFN-λ4. Secondly, the induction of differentially expressed gene pattern suggested that IFN-λ3 has a stronger effect on M2-MDMs compared to M1-MDMs while the reverse is true for IFN-λ4.

IFN-kappa inhibits HPV31 transcription by inducing Sp100 proteins

Project description:Using doxycycline-inducible IFN-kappa expression in CIN612-9E cells, which maintain extrachromosomally replicating HPV31 genomes, we demonstrate that IFN-kappa inhibits the growth of these cells and reduces viral transcription and replication. Interestingly, the initiation of viral early transcription was already inhibited 4-6h after IFN-kappa expression. This was also observed with recombinant IFN-beta suggesting a common mechanism of IFNs. RNA-seq analysis identified 1367 IFN-kappa regulated genes of which 221 were modulated >2-fold. The majority of those (71%) matched known ISGs confirming that IFN-kappa acts as a bona fide type I IFN in hr-HPV-positive keratinocytes. RNAi and co-transfection experiments indicate that the inhibition of viral transcription is mainly due to the induction of Sp100 proteins by IFN-kappa. CIN612-9E/pInd-IFN-kappa were induced for 4h with 1Âµg/ml doxycyclin or not. Three biological replicates were analyzed.

High-throughput small RNA sequencing of the human placenta at first and third trimester with fetal sex differences analysis

Project description:Human placenta bulk small RNA-seq from healthy pregnancies without infertility, from n=113 first trimester (58 female, 55 male) and n=47 third trimester (19 female, 28 male) tissue samples. Tissue was collected at Cedars-Sinai Medical Center in Los Angeles, California, USA. First trimester placenta was collected at 70-102 days of gestation from leftover chorionic villus sampling for prenatal genetic diagnosis. Third trimester placenta was collected after delivery at 254-290 days gestation from the fetal side near the umbilical cord insertion site beneath the amnion. Mothers with pre-existing diabetes or hypertension were excluded. All pregnancies were conceived without fertility treatments, were normal karyotype, and resulted in live singleton births. The average parental age was advanced (over 35 years old) but PCA analysis did not show clustering by either maternal or paternal age. Gonzalez et al 2021 [PMID: 34030457] analyzes similarities and differences between first and third trimester miRNA expression overall. Flowers et al 2021 focuses on the effect of fetal sex on miRNA expression across gestation.
