Project description:ABX464, a new drug for curing HIV and treating inflammatory diseases induces upregulation of the anti-inflammatory miR-124. We used microarrays to show the implication of ABX464 in the biogenesis of small noncoding RNAs. So, we decided to evaluate if miRNAs or small nucleolar RNAs (snoRNAs) were differentially regulated by ABX464.
Project description:The expression of 30362 plant genes from uninfected flowers of Boechera stricta, uninfected steam and leaves of B. stricta and infected B. stricta with Puccinia monoica forming pseudoflowers. We hybridized cDNA from each sample to an Arabidopsis thaliana gene expression 4x72K format NimbleGen array (ATH6_60mer_expr).
Project description:A comparison was made between the THP-1(Human monocytic leukemia cells - TIB-202; ATCC) transcriptional responses of; (i) uninfected versus Coxiella burnetii NMII infected and (ii) uninfected versus Coxiella burnetii NMII infected THP-1 cells transiently treated with bacteriostatic levels (10μg/ml) of chloramphenicol (CAM). Briefly, infections were initiated and cultured in parallel with uninfected cells. At 48 hours post infection (hpi), media containing CAM (10μg/ml) was added to one set of cells (uninfected and infected THP-1 cells) and culturing was continued. The other set of cells were mock treated with normal media. Total RNA was isolated at 72 hpi from all conditions. Microarrays were performed for both condition sets and the results from each of the two microarrays were compared to define the host genes modulated by de novo C. burnetii NMII protein synthesis.
Project description:Human fibroblasts were infected with GFP-expressing Salmonella enterica serovar Typmimurium and further separated by Fluorescence Activated Cell Sorting. RNA from infected and uninfected cells sub-populations were used for genome-wide expression studies
Project description:Hemolymph was characterized from Diaphorina citri adults infected with the phytopathogen, Candidatus Liberibacter asiaticus (CLas) and compared with that from uninfected psyllids. This study identified 5531 and 3220 peptides within infected and uninfected hemolymph using nano LC-MS/MS. A reduced number of proteins were detected for D. citri and all known endosymbionts within infected hemolymph as compared to uninfected hemolymph. A large number of immune defense proteins were absent from D. citri hemolymph; however, a single recognition protein (PGRP), two serine protease inhibitors, three prophenoloxidase (proPO) enzymes, and a single serine protease in an uninfected D. citri were detected. The hemolymph is nearly devoid of nutrient storage proteins. This is the first proteomic analysis of D. citri hemolymph that also analyzes the components contributed by all of the endosymbionts. By comparing the contribution of each endosymbiont (CCR, CPA,WB) in the presence and absence of CLas infection, this study provides initial insights regarding the hemolymph response to microbial community shifts associated with D. citri infection status. Our data also present potential protein targets for analysis and disruption of CLas transmission that may facilitate management of huanglongbing (HLB) caused by CLas in citrus.
Project description:Genome wide DNA methylation profiling of PBMC from South African patients either infected with HIV only or coinfected with HIV and tuberculosis (TB). The Illumina Infinium 27k Human DNA methylation Beadchip was used to obtain DNA methylation profiles from PBMC samples. Samples included 19 HIV patients and 20 HIV/TB co-infected patients.
Project description:Human fibroblasts were infected with GFP-expressing Salmonella enterica serovar Typmimurium and further separated by Fluorescence Activated Cell Sorting. RNA from infected and uninfected cells sub-populations were used for genome-wide expression studies 3 independent experiments enabled us to obtain 3 infected and 3 uninfected sub-populations.
Project description:Mice were infected with wild type or ESX-1-deficient (deltaRD1) Mycobacterium marinum. 14 days post infection, infected and uninfected neutrophils from the infected tissue were sorted for single cell RNA sequencing analysis.
