Project description:Ectromelia virus (ECTV) has emerged as a valuable model for investigating the host-orthopoxvirus relationship as it relates to pathogenesis and the immune response. ECTV causes mousepox in most strains of mice, including BALB/c and DBA/2, and these are therefore classified as susceptible mice. Conversely, C57BL/6 and certain 129 strains display limited pathology and a very low mortality, and are thus classified as resistant. To understand the host genetic factors of different mouse strains in response to ECTV infection, we carried out a microarray analysis using Affymetrix Gene-Chip Mouse Genome Arrays of spleen tissues from BALB/c and C57BL/6 mice at 3 and 10 days post-ECTV infection. Differential Expression of Genes (DEGs) analyses revealed distinct differences in the gene profiles of resistant and susceptible mice infected with ECTV. Gene ontology and KEGG pathway analysis showed that the DEGs of susceptible mice were involved mainly in immunity, apoptosis, spliceosomes and cancer-related pathways, while the DEGs of resistant mice were largely involved in MAPK signaling and leukocyte transendothelial migration. This suggests that the susceptible BALB/c mice have a stronger response than the resistant C57BL/6 mice to ECTV infection. The BALB/c mice showed a strong induction of interferon-induced genes (ISGs), including guanylate binding proteins (GBPs), myxovirus resistance protein (Mx) GTPases, oligoadenylate synthetase (OAS) and IFN-induced protein with tetratricopeptide repeats (IFIT) family proteins, while the C57BL/6 mice upregulated more genes related to metabolic pathways. This suggests that the susceptible BALB/c mice have a stronger response than the resistant C57BL/6 mice to ECTV infection.

Project description:The development and outcome of cerebral malaria (CM) reflects a complex interplay between parasite-expressed virulence factors and host response to infection. To simultaneously analyze transcriptional programs in both parasite and host over the course of infection, we created microarrays to concurrently detect transcripts in the genomes of both Plasmodium berghei and mouse. Analysis of RNA from brain, lung, liver, and spleen of mice infected with P. berghei ANKA showed that parasite gene expression is readily detected in whole organ RNA. Comparison of CM-susceptible (C57BL/6) and CM-resistant (BALB/c) mice showed that both host and parasite display distinct organ-specific transcriptional signatures in susceptible versus resistant animals. Host genes whose expression differs between CM-resistant and CM-susceptible mice, at either baseline or induced by infection, tend to relate to humoral and immune response, complement activation, or cell-cell interactions, suggesting differences in immune function that may directly underlie protection from or susceptibility to CM. P. berghei, in contrast, displayed differential expression of genes related to apparent biosynthestic activities, with the majority of transcriptional activity observed in the lung. These data show that analysis of host and parasite gene expression profiles by hybridizing infected host samples to a single microarray is feasible, and can facilitate dissection of complex host-pathogen interactions.

Project description:The gene expression profiles were investigated and compared in spleen, lungs and liver of susceptible (BALB/c) and resistant (C57BL/6) hosts to identify genes participated in survival and virulence functions encoded in the B. pseudomallei genome. Subsequently, genes with unknown function and located with virulence gene clusters or suspected to be transcription regulator were selected for a novel virulence gene investigation DNA microarray was used to compare gene expression profiles of B. pseudomallei 1909a in spleen, lung and liver of infection-susceptible BALB/c mice (Th2 prototype) and infection-resistant C57BL/6 mice, (Th1 prototype) during an acute infection. The gene expression profile of B. pseudomallei in culture medium at mid-log phase was used to identify genes that expressed higher or lower in vivo when compared to the in vitro gene profile KEYWORDS: Gene expression

Project description:Transcriptional profiling of chicken spleen tissues from Marek's disease virus (MDV) infected and non-infected control individuals from three inbred chicken lines 63, 72, RCSM with varying disease resistance characteristics. Line 63 is highly resistant; line 72 is highly susceptible; and line RCSM has intermediate resistance. Our goal was to investigate the genetic basis of systemic variation in disease resistance in these genetically similar individuals. Three time points were chosen at different stages of disease progression - 5 days post-infection (dpi) - early cytolytic phase; 10 dpi - latent phase; and 21 dpi - late cytolytic phase with 4 replicates at each stage.

Project description:To understand pathogenicity and in planta transcriptional reprogramming, expression profiles of U. virens during infection of the resistant and susceptible cultivars were analyzed using RNA-seq data. Predicted host-pathogen interaction database (PHI-base) genes that are probably involved in host-pathogen interactions were found to be significantly enriched in fungal differential expressed genes from both rice genotypes, indicating their potential roles in pathogenicity of U.virens. Our results also indicate that genes for secreted proteins and secondary metabolism are highly enriched in the transcriptome during early infection of susceptible cultivars. GO enrichment analysis suggest that bilogical processes required for successful infection of U. virens are greatly suppressed in the resistant cultivars.

Project description:This experiment compared gene expression in the duodenum of [1] weaned genetically resistant sheep and weaned genetically susceptible sheep (84 days old) [2] genetically resistant sheep and genetically susceptible sheep that have been naturally challenged once with nematodes (175 days old) and [3] genetically resistant sheep and genetically susceptible sheep that have been naturally challenged twice with nematodes (276 days old). At each time point (T = 84, 175, 276 days) a four factorial design was used with four resistant animals and four susceptible animals. Each animal in the resistant group was compared to each animal in the susceptible group incorporating dye swaps. At T = 84 the platform GPL4072 was used. At T = 175 days the platform GPL4076 was used and at T =276 days the platform GPL4077 was used.
