Transcriptomic expression profiles of SPF chicken-lung infected with duck-origin H7N9 subtype avian influenza virus

Project description:In order to elucidate the expression changes of host genes of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus. The lungs of SPF chickens infected with duck-origin H7N9 subtype avian influenza virus were collected and high throughout sequenced. Compared with the control group, there were 740 differentially expressed genes were obtained in infection group, including 602 up-regulated genes and 138 down-regulated genes. The analysis of the GO items showed that the differentially expressed genes were involved in immune responses and inflammatory responses. The results of KEGG analysis showed that 7 pathways were enriched significantly, in those the Toll-like pathway had 11 up-regulated genes, namely IL-6, TLR4, Pik3, IRF7, MD-2, IRF5, MYD88, CD86, STAT1, TLR2, and CCL4. There were 7 up-regulated genes in NOD-like receptor signaling pathway, which were IRF7, CTSB, P2RX7, CYBB, PSTPIP1, HSP90AA1, and NAMPT. In Toll-like signaling pathway，TLR4 was activated by MD-2 after viral infection, and then activated downstream IRF5. At the same time, the NLRP3 inflammasome also played an important role in the process of H7N9 virus infection.

Responses to DNA vaccine against H5 virus in White Leghorn SPF chickens.

Project description:White Leghorn SPF chickens were immunized with two doses of DNA vaccine, based on the hemagglutinin (HA) DNA from H5N1 virus, in comparison to the control group, which was administered an empty vector (pCI). Gene expression changes in the spleens of chickens were investigated at 7 day post booster dose.

Integrated host and viral transcriptome analyses reveal pathology and inflammatory response mechanisms to ALV-J injection in SPF chicken

Project description:Avian leukosis virus (ALV) causes substantial economic losses from mortality and decreased performance in poultry industry. To characterize the response to ALV challenge, we developed a novel methodology that combines four datasets: mRNA expression and their associated regulatory factors of miRNA and lncRNA, and ALV gene expression. Specific Pathogen-Free (SPF) layer chickens were assigned to the ALV-infected or control group. Spleen samples (n=6) were collected at 40 days post injection (dpi), and sequenced. Comparing the infected and non-infected groups, 864 genes, 7 miRNAs and 17 lncRNAs were differentially expressed.

MicroRNA expression in chicken cecum following Campylobacter jejuni infection

Project description:SPF leghorn chickens were infected with C. jejuni. The cecum were collected at 8h post infection for total RNA isolation. The significantly expressed microRNAs between infected and non-infected chickens were identified through Solexa sequencing technology. Two libraries were made from each group, in total, four libraries were used for Solexa sequencing.

Comparing Gut Microbial Composition and Functional Adaptations between SPF and Non-SPF pigs

Project description:The gut microbiota is closely associated with digestion, metabolism, immunity, and host health. The imbalance of the microbial community in livestock directly affects their well-being and, consequently, productivity. The composition and diversity of the gut microbiota are influenced not only by host genetics but also by environmental factors such as the microbial complexity of the rearing environment, feeds, and antibiotics. Here, we focus on the comparison of gut microbial communities in miniature pigs developed for xenotransplantation in specific pathogen-free (SPF) and conventional (non-SPF) facilities. To identify the disparities in gut microbial composition and functionality between these two environments, 16S RNA metagenome sequencing was conducted using fecal samples. The results revealed that the non-SPF pigs had higher gut microbiota diversity than the SPF pigs. The genera Streptococcus and Ruminococcus were more abundant in SPF pigs than in non-SPF pigs. Blautia, Bacteroides, and Roseburia were exclusively observed in SPF pigs, whereas Prevotella was exclusively found in non-SPF pigs. Carbohydrate and nucleotide metabolism, as well as environmental information processing, were predicted to be enriched in SPF pigs. In addition, energy and lipid metabolism, along with processes related to genetic information, cellular communication, and diseases, were predicted to be enriched in non-SPF pigs. This study makes an important contribution to elucidating the impact of environments harboring a variety of microorganisms, including pathogens, on the gut microbiota of miniature pigs. Furthermore, we sought to provide foundational data on the characteristics of the gut microbiota in genetically modified pigs, which serve as source animals for xenotransplantation.

Next Generation Sequencing Facilitates Quantitative Analysis of H5N1 Wild Type and NS1-truncated Lung Transcriptomes in SPF chickens

Project description:H5N1 highly pathogenic avian influenza (HPAI) has raised global concern for causing huge economic losses in poultry industry. By using reversal genetic technical, we have rescued a H5 wild-type virus rS and its NS1-truncated virus S-NS99, harboring only 99 amino acids in the amino terminus of NS1. We then used a high-throughput RNA-seq method to analyze host and pathogen transcriptomes in the lungs of chickens infected with rS and S-NS99. Sequenced numbers of viral transcripts and expression levels of host immune-related genes at 1 day post infection (dpi) were higher in rS-infected than S-NS99-infected chickens. The numbers of immune response of rS-infected chickens by Gene Ontology (GO) enrichment were higher than S-NS99-infected chickens. KEGG pathway analysis revealed rS infection could provoke significantly stronger immune response than S-NS99. Collectively, our data provide new insight into the underlying mechanisms of the diﬀerential length NS1 of avian influenza viruses.
