Project description:Acquisition of a new strain of non-typeable Haemophilus influenzae (NTHi) is often associated with exacerbation of chronic obstructive pulmonary disease (COPD). We have previously reported that COPD patients who are homozygous null for SIGLEC14 gene is less susceptible to COPD exacerbation than those who have wild-type allele with functional SIGLEC14 gene. In order to gain insight into the mechanism behind the COPD exacerbation, and to find new clues that may lead to the discovery of objective biomarker of COPD exacerbation, Siglec-14/THP-1 and Siglec-5/THP-1 cell lines, which mimic monocytes from homozygous wild-type and homozygous SIGLEC14-null person, respectively, were incubated with or without NTHi, and their gene expression profiles were compared by using Affymetrix Human Genome U133 Plus 2.0 Array. Four samples (2 cell lines x 2 conditions) were analyzed. No replicates were made.

Project description:So far, we have found phorbol 12-myristate 13-acetate (PMA) induced ubiquitin specific peptidase (USP) 2b isoform in myeloid leukemia cell lines such as HL60, THP-1, and U937. HL60, THP-1, and U937 undergoes differentiation into macrophage-like cells after stimulation with phorbol ester. To explore molecular function of USP2 in macrophages especially during lipopolysaccharide(LPS) response, we assess expression profiles of HL60-derivatives continuously expressing shRNA for USP2 and control shRNA.

Project description:Chronic obstructive pulmonary disease (COPD) is a progressive inflammatory lung disease and the third leading cause of death globally. Nontypeable Haemophilus influenzae (NTHi) and Moraxella catarrhalis (Mcat) are common pathogens in individuals with COPD. Acquisition of NTHi or Mcat can cause acute exacerbations of COPD. NTHi and/or Mcat can also persist for months in the lower airways and lead to chronic inflammation. We hypothesized that infection by NTHi or Mcat, singly or during coinfection, requires regulation of specific bacterial and host cell pathways. We investigated this phenomenon using an in vitro cell culture model consisting of lung carcinoma H292 cell lines, infected with NTHi, Mcat, or both species. Samples were fractionated into “apical fluid”, containing free floating bacteria, and adhered/invaded bacteria on or within H292 cells. We used transcriptomic profiling with RNA-seq and various bioinformatic analyses to disentangle host-pathogen interactions in epithelial cell infection from the perspective of each species. Several biological pathways were differentially regulated across all conditions (31, NTHi; 22, Mcat; and 169, Human). NTHi transcriptomic profiles differed during single and coinfection; examples included downregulation of iron-sulfur metabolism (IscR regulon) and differential regulation of quorum sensing in coinfection compared to single infection. Mcat was comparatively less affected by the presence of NTHi during coinfection. H292 epithelial cells responded broadly to all infections with distinct responses to single and coinfection. Enriched host pathways included influenza/interferon/Wnt and proinflammatory responses. These findings suggest common and distinct processes involved in NTHi and/or Mcat induced COPD pathogenesis and have implications for therapeutic intervention.

Project description:Gene expression profiles of human cell (THP-1) lines exposed to a novel Daboiatoxin (DbTx) isolated from Daboia russelli russelli, and specific cytokines and inflammatory pathways involved in acute infection caused by Burkholderia pseudomallei. Experiment Overall Design: 1. Group I:- Human monocytic macrophage (THP-1) cell lines grown in the culture medium without any bacterial infection served as untreated control group (Three Biological Replicates). Experiment Overall Design: 2. Group II:- THP-1 cells were infected with Burkholderia pseudomallei (A600 nm = OD 0.6, ~5 x 107 cfu/ml) for 24h served as a disease control group (Three Biological Replicates). Experiment Overall Design: 3. Group III:- THP-1 cells were infected with B. pseudomallei and treated with Daboiatoxin (0.5 mM) isolated from Daboia russelli russelli venom served as a treatment group (Three Biological Replicates). Experiment Overall Design: 4. Group IV:- THP-1 cells were infected with B. pseudomallei (A600 nm = OD 0.6, ~5 x 107 cfu/ml) treated with standard antimicrobial drug ceftazidime (10mg/ml) served as a drug control (Three Biological Replicates). Experiment Overall Design: 5. Group V:- THP-1 cells were exposed to Daboiatoxin (0.5 mM) without bacterial infection (Three Biological Replicates).

Project description:In this study, by using two classical macrophage cell models, RAW264.7 cell line from mouse and THP-1 cell line from human, combined with the applications of two classical stimulation methods for inducing classical activated (M1) and alternatively activated macrophages (M2) from the monocytes of both cell lines, we comprehensively identified and quantified proteins in different types of macrophages from both cell lines through high-throughput proteomics.
