ABSTRACT: proteomes of host cells infected with BCG during the early stage at 12, 24, and 48 h respectively to identify the potential bacterial components derived from BCG.
ORGANISM(S): Mycobacterium Tuberculosis Variant Bovis Bcg Str. Pasteur 1173p2
Project description:Using next-generation sequencing, we sequenced transcriptomes of A. thaliana plants infected by the pathogenic and the symbiotic fungus and analyzed plant and fungal gene expression changes between pathogenic and symbiotic interactions. Infected plants were sampled at early infection stages, 12, 24, 48 and 96 HPI (hours post inoculation)
Project description:Exosomes derived from S. Typhimurium-infected RAW264.7 macrophages (24 and 48 hpi) were isolated by differential ultracentrifugation. Equal protein samples in triplicates were subjected to protein extraction and separation by SDS-PAGE. Protein bands excised from each lane were reduced, alkylated, and digested with trypsin. Peptide pools were desalted by C18 columns and analyzed by liquid chromatography-Orbitrap Fusion tandem mass spectrometry
Project description:The fungal pathogen Sclerotinia sclerotiorum infects a broad range of dicotyledonous plant species and is the causative agent of stem rot in Brassica napus. To elucidate the mechanisms underlying the defense response, we studied the patterns of gene expression in a partially resistant variety of ZhongYou 821 (ZY821) and a susceptible line from Westar over five time points, 6, 12, 24, 48, and 72 hours post-inoculation (hpi) using a B. napus oligonucleotide microarray. Maximum differential gene expression was observed at 48 hpi in both genotypes with ZY821 responding more quickly than Westar. Specific sets of genes exhibited higher levels of expression at the earlier stages of the infection (6-12 hpi), including genes encoding defense-associated proteins such as chitinases, glucanases, osmotins and lectins and genes encoding transcription factors belonging to the zinc finger, WRKY, AP2, and MYB classes. Genes encoding enzymes involved in JA, ethylene, and auxin synthesis were induced in both genotypes, as were those for gibberellin degradation. Changes in metabolic pathways affecting carbohydrate and energy metabolism appeared to be directed toward shuttling carbon reserves to the TCA cycle. Genes involved in glucosinolate and phenylpropanoid biosynthesis were highly up-regulated suggesting that secondary metabolites are also important components of the response to S. sclerotiorum in B. napus. Keywords: Time course, and infected vs mock infected
Project description:Japanese Encephalitis Virus (JEV) modulates different proteins at different time points of infection to favour its propagation in the host cells. The dysregulation of intertwined pathways in the host has implications for virus pathogenesis. This study aims to decipher the global proteome of Japanese encephalitis infected THP-1 derived macrophages at 24 hours post-infection and 48 hours post-infection, which will further help to deduce the interwoven pathways regulated upon JEV infection.

Project description:The analysis of differentially regulated mRNAs candidates in THP-1 cells infected with H37Rv was conducted, comparing them to both uninfected THP-1 cells and transfected reference samples. THP-1 cells are monocytes that differentiate into macrophages after being treated with PMA for 48 hours. Total RNA was isolated from the infected and transfected THP-1 cells at 24 hours post-infection.

To elucidate the mechanisms underlying the defense response, we studied the patterns of gene expression in a partially resistant variety of ZhongYou 821 (ZY821) and a susceptible line from Westar over five time points, 6, 12, 24, 48, and 72 hours post-inoculation (hpi) using a B. napus oligonucleotide microarray. For each cultivar, a two-dye experiment was run comparing infected to mock-infected stem tissue. For each time point, 6 microarray slides were done (3 biological replicates, with a dye swap for each biological replicate). This SuperSeries is composed of the SubSeries listed below.
Project description:We used RNA-seq to identify gene expression changes in C. elegans after 1 hr, 4 hr, 12 hr and 24 hr of exposure to Myzocytiopsis humicola extract; and after 12 hr, 24 hr and 48 hr of infection with Myzocytiopsis humicola
Project description:Primary human monocytes were isolated from four healthy donors. Monocytes were differentiated into macrophages, infected with virulent Mycobacterium tuberculosis (Mtb), strain H37Rv, for 24 or 48 hours, at a multiplicity of infection of 5 or 10. Following infection, infected cells and time-matched uninfected controls were harvested, total RNA including small RNAs was isolated and used for next-generation small RNA sequencing. Small RNA sequencing data was processed using miRge2.0, including a novel miRge2.0-based tRF detection tool. Processed data was used to determine differential expression of microRNAs and differential production of tRNA-derived fragments (tRFs) during infection with Mtb.
