Project description:The current level of knowledge on transcriptome responses triggered by Caesalpinia sappan (CS) extract in porcine peripheral blood mononuclear cells (PBMCs) after porcine reproductive and respiratory syndrome virus (PRRSV) infection is limited. Therefore, in the present study, we aimed to detect significant genes and pathways involved in CS extract supplementation responsiveness of PBMCs after PRRSV infection. RNA sequencing was conducted on PBMCs, which were isolated from six weaned piglets. The resultant transcriptional responses were examined by mRNA sequencing. Differential expression analysis identified 263 and 274 differentially expressed genes (DEGs) between the PRRSV and CTRL groups, and the PRRSV+CS and CTRL groups, respectively. Among these, ZNF646 and KAT5 emerged as the most promising candidate genes, potentially influencing the interaction between PRRSV-infected PBMCs and CS extract supplementation through the regulation of gene networks and cellular homeostasis during stress. Two pathways were detected to be associated with CS extract supplementation responsiveness: the cellular response to stress pathway and the NF-kB signaling pathway. Consequently, our study reveals a novel mechanism underlying cellular stress response and the NF-κB signaling pathway in PRRSV-infected PBMCs, and identifies a potential application of CS extract for activating the NF-κB signaling pathway. In conclusion, by supplementing CS extract in PBMC cells infected with PRRSV, we found that CS extract modulates PRRSV infection by inducing cellular stress, which is regulated by the NF-κB signaling pathway. This induced stress creates an adverse environment for PRRSV survival. This study contributes to a deeper understanding of the therapeutic targets and pathogenesis of PRRSV infection. Importantly, our results demonstrate that CS extract has the potential to be a candidate for modulating PRRSV infection.

Project description:The goal of this study is to characterize the human immune responses to the live attenuated Herpes zoster vaccine Zostavax, to understand the molecular and cellular mechanisms that lead to antibody production and T cell induction, and to understand the difference between young and elderly healthy adults. The overall data collection included antigen specific assays, flow cytometric profiling of innate and adaptive cell populations, measurement of serum cytokines, and transcriptomic and metabolomics signatures. Zostavax induced robust antigen-specific antibody responses, and significant T cell responses. A number of gene pathways were upregulated after vaccination. Using our previously developed blood transcription modules, we also identified transcriptomic correlates to antibody response. Furthermore, this study revealed strong association between PBMC transcriptomics and plasma metabolomics. Integrative analysis of orthogonal datasets from metabolomics, transcriptomic and immune profiling facilitated a temporal reconstruction of Zostavax induced biological networks culminating in antibody responses , and the delineation of novel molecular correlates of vaccine immunity.

Project description:Porcine reproductive and respiratory syndrome (PRRS), caused by PRRS virus (PRRSV), is the most economically important disease in pig populations. Lung damage is one major pathological condition following PRRSV infection, often leading to animal death. In vivo, PRRSV productive infection occurs predominately in alveolar macrophages of the lung. Here, transcriptome profiling of pulmonary alveolar macrophages (PAMs) from Tongcheng piglets pre- and post- infection of highly pathogenic PRRSV has been performed using porcine Affymetrix GeneChip.

Project description:Human papilloma (HPV) virus-like particle (VLP) vaccines were recently licensed. Though neutralizing antibody titers are thought to be the main effectors of protection against infection, early predictors of long-term efficacy are not yet defined and a comprehensive understanding of innate and adaptive immune responses to vaccination is still lacking. Here, microarrays were used to compare the gene expression signature in HPV-16 L1 VLP-stimulated PBMC from 17 vaccine and 4 placebo recipients before vaccination, and 1 month after receiving the second immunization. Vaccination with HPV-16 L1 VLP was associated with modulation of genes involved in the inflammatory/defense response, cytokine, interferon and cell cycle pathways in VLP-stimulated PBMC. In addition, there was up-regulation of probesets associated with cytotoxic (GZMB, TNFSF10) and regulatory (INDO, CTLA4) activities. The strongest correlations with neutralizing antibody titers were found for cyclin d2 (CCND2) and galectin (LGALS2). Twenty-two differentially expressed probesets were selected for confirmation by RT-PCR in an independent sample set. Agreement with the microarray data was seen for over two-thirds of these probesets. Up-regulation of immune/defense response genes by VLP, in particular interferon-induced genes was observed in PBMC collected prior to vaccination, with many of these genes being further induced following vaccination. In conclusion, we used gene expression profiling to identify important innate and adaptive response related- genes induced by vaccination with HPV VLP. Further studies are needed to identify gene expression signatures of immunogenicity and long-term protection with potential utility in prediction of long-term HPV vaccination outcomes in clinical trials. Experiment Overall Design: Microarrays (Affymetrix Human Focus) were used to compare the gene expression signature in PBMCs stimulated for 3 days with media alone, Sf9/baculovirus insect cell lysate, and HPV-16 L1 VLP expressed from baculovirus-infected Sf9 insect cells from 17 vaccine and 4 placebo recipients before vaccination, and 1 month after receiving the second immunization (2 months after the initial immunization. Post-vaccination baculovirus sample for Pt078 and pre-vaccination baculovirus sample for Pt082 failed QC.

Project description:Vaccine development involves time-consuming and expensive evaluation of candidate vaccines in animal models. As mediators of both innate and adaptive immune responses dendritic cells (DCs) are considered to be highly important for vaccine performance. Here we evaluated in how far the response of DCs to a vaccine in vitro is in line with the immune response the vaccine evokes in vivo. To this end, we investigated the response of murine bone marrow-derived DCs to whole inactivated virus (WIV) and subunit (SU) influenza vaccine preparations. These vaccine preparations were chosen because they differ in the immune response they evoke in mice with WIV being superior to SU vaccine through induction of higher virus-neutralizing antibody titers and a more favorable Th1-skewed response phenotype. To evaluate if in vivo immunogenicity is reflected by DC reactions in vitro we studied the gene expression signature of murine bone-marrow-derived conventional DCs (cDCs) upon stimulation with WIV or SU influenza vaccine or, for reasons of comparison, with live influenza virus. Dendritic cells stimulated with PBS served as a control. Gene expression analysis was performed on samples 4, 12 and 24 hours after the start of stimulation.

Project description:The initial interaction of porcine reproductive and respiratory virus (PRRSV) with the immune system is of critical importance for immunological and clinical outcomes. PRRSV infection is associated with inefficient or aberrant immune responses: weak and delayed neutralizing antibody responses and erratic IFN-γ producing T-cells specific response. The lack of vaccine correlates capable of predicting protection has largely hampered the development of new efficacious PRRS vaccines. The objective of this study was to determine if systems biology (1) could be used to identify molecular pathways associated with “good” and “bad” PRRSV vaccine responders in terms of their intensity of IFN- γ secreting cell responses.

Project description:A CNV map in pigs could facilitate the identification of chromosomal regions that segregate for important economic and disease phenotypes. The goal of this study was to identify CNV regions (CNVRs) in pigs based on a custom array comparative genome hybridization (aCGH). We carried out a custom-made array comparative genome hybridization (aCGH) experiment in order to identify copy number variations (CNVs) in the pig genome analysing animals of diverse pig breeds (White Duroc, Yangxin, Erhualian, Tongcheng, Large White, Pietrain, Landrace and Chinese new pig line DIV ) using a tiling oligonucleotide array with ~720,000 probes designed on the pig genome (Sus scrofa genome version 9.0). In this study, a custom-made tiling oligo-nucleotide 720k array was used with a median probe spacing of 2506 bp for screening 12 pigs with a female Duroc as the reference. WD: White Duroc (♀); YX: Yangxin (♂); EH: Erhualian (♀); TC: Tongcheng (♀); LW: Large White (♀); PT: Pietrain (♂); LD1: Landrace × DIV pig 1 (♂); LD2: Landrace × DIV pig 2 (♀); DIV1: Chinese new pig line DIV 1 (♀); DIV2: Chinese new pig line DIV 2 (♀); L1: Landrace 1 (♂); L2: Landrace 2 (♂).

Project description:Porcine reproductive and respiratory syndrome (PRRSV) is a devastating pathogen for the pig industry worldwide. PRRSV mainly infects porcine alveolar macrophage (PAM). In the present study, single-cell RNA sequencing (scRNA-seq) was employed to characterize the host transcriptome responses of PAMs infected with a virulent PRRSV strain in vivo and ex vivo. Increase ofpro-inflammatory and anti-apoptotic genes was correlated with the increase of infection (expression of the virus ORF7 transcript).
