RNA-seq of RTS11 Macrophage-like cell line treated with Beta-glucans against untreated controls

ABSTRACT: This experiment focused on the transcriptomic responses of the rainbow trout spleen macrophage-like cell line (RTS11) in response to β-glucans (M-glucans, Biotec). RTS11 was cultured at the Scottish Fish Immunology Research Centre, University of Aberdeen. M-glucans was provided by Skretting AI. Samples were treated for 4hrs with either M-glucans or left untreated as controls (n=4). To establish responses to β-glucans, total RNA was extracted for RNA-seq examination. Library preparation and sequencing was carried out by Novogene Ltd, with downstream analysis being carried out at the SFIRC. As a result, a total of 8 samples were used to identify responses to M-glucans, 4 control and 4 stimulated samples were used for the analysis.

RNA-seq of human PMA-differentiated cell line THP-1 trained with DCATH-2 peptide against untreated controls after a 3-day rest followed by stimulation with medium or lipopolysaccharide

Project description:Trained innate immunity has been shown for human macrophages, i.e. a primary stimulation with specific compounds such as Beta-glucans, BCG vaccine or oxidized LDL generates an innate memory capacity that leads to an amplified pro-inflammatory reaction to various microbial components when restimulated days later. In this study, phorbol ester differentiated THP-1 cells were used as a model for human macrophages. The aim of this experiment was to map the biological processes involved in DCATH-2 peptide trained THP-1 cells versus control cells without restimulation and after restimulation with lipopolysaccharides.

Integrating proteomic data with metabolic modelling provides insight into key pathways in Bordetella pertussis biofilms

Project description:Pertussis, commonly known as whooping cough is a severe respiratory disease caused by the bacterium, Bordetella pertussis. Despite widespread vaccination, pertussis resurgence has been observed globally. The development of the current acellular vaccine (ACV) has been based on planktonic studies. However, recent studies have shown that B. pertussis readily forms biofilms. A better understanding of B. pertussis biofilms is important for developing novel vaccines that can target all aspects of B. pertussis infection. This study compared the proteomic expression of biofilm and planktonic B. pertussis cells to identify key changes between the conditions. Major differences were identified in virulence factors including an upregulation of toxins (adenylate cyclase toxin and dermonecrotic toxin) and strong downregulation of pertactin and type III secretion system proteins in biofilm cells. To further dissect metabolic pathways that are altered during the biofilm lifestyle, the proteomic data was then incorporated into a genome scale metabolic model using the integrated metabolic analysis tool (iMAT). The analysis revealed that planktonic cells utilised the glyoxylate shunt while biofilm cells completed the full tricarboxylic acid cycle. Differences in processing aspartate, arginine and alanine were identified as well as unique export of valine out of biofilm cells which may have a role in inter-bacterial communication and regulation. Finally, increased polyhydroxybutyrate accumulation and superoxide dismutase activity in biofilm cells may contribute to increased persistence during infection. Taken together, this study modelled major proteomic and metabolic changes that occur in biofilm cells which helps lay the groundwork for further understanding B. pertussis pathogenesis.

RhoA inhibitor treatment of spinal cord injury: Deep inside mechanism understanding for a better use

Project description:The present study shows by in vivo experiments, the impact of RhoA inhibitor treatment using a functionalized alginate scaffold and the beneficial results at the early stage by increasing neurites outgrowth and synaptic contact. However, 7 days after treatment a plateau is obtained in BBB score. We thus performed an in vitro and proteomic associated to systemic biology analyses of secreted factors from ND7/23 DRG cell line incubated with secreted factors from different segments after spinal cord lesion treated wih RhoA inhibitor. We then performed a time course proteomic study from the DRG cells in same conditions as for the secretome. The results taken together allow a better understanding of the mechanisms occurring in both side of the lesion and led a positive impact of the treatment on growth cone guidance in both sides of the lesion (Rostral 1 and Caudal 1). We identified the transcription factors involved in time course at the beginning of the treatment and the growth cone factors (receptors, ligands, signaling pathways) implicated in this time course. We also demonstrate the involvement of immunoglobulins (IgG1, IgG2) in this process. Anti-GFAP seem to bind to its own receptor in DRG cells when neurite outgrowth is initiated and thus modulate the process like in traumatic brain injury. These results open the door of a concomitant treatment at both sides of the lesion with RhoA inhibitor. However, we also pointed that RhoA inhibitor treatment led to an inhibition of several factors implicated in neurogenesis reflecting a global inhibition at term as detected in vivo that reached 2 weeks after treatment. RhoA inhibitor treatment is useful to initiate the neurogenesis process but needs to be supplied by a second treatment for increasing synaptic connections and the neuron reconnections.

Transcription profiling of rat control subplate neurons with few synapses and cocultured subplate neurons with induced synaptogenesis

Project description:The transcriptional events accompanying synaptogenesis are largely unknown, or have been studied in systems in which synapse formation occurs gradually over time. With a system in which synaptogenesis is synchronized and controllable, molecular or biochemical techniques can be used to examine cellular events across cultures on a wide scale, as synapses develop. Here, we have triggered synaptogenesis in immunopurified subplate neurons by coculturing with cortical feeder layers and have used microarrays to investigate the transcriptional events occuring in this more defined and controllable system. Experiment Overall Design: Affymetrix rat GeneChip microarrays were used to assess whether coculturing induces transcriptional changes in subplate neurons. Subplate synapses develop rapidly following coculturing; an exposure to the feeder layer of only 48 hours is sufficient to detect a significant increase in the density of synapses, and is as effective as longer durations. Within the first few minutes or hours of a cell's response to an exogenous signal, any primary transcriptional events are expected to involve activation of immediate early genes (IEGs), often transcription factors themselves, which may then turn on downstream target response genes encoding factors to be delivered to sites of action, such as synapses. With the aim of searching for such downstream genes, microarrays were performed after 24 hours of coculturing, an intermediate timepoint between the likely phase of IEG transcription and the large wave of synaptogenesis seen between 24 and 48 hours of coculturing. Additional microarrays were also performed after 96 hours of coculturing to assess transcriptional changes that might occur over longer timescales. Five biological replicates of control and cocultured neurons at 24 and 96 hours were used, for a total of 20 microarrays.

Candida albicans induces monocyte training via epigenetic programming through a dectin 1-dependent pathway

Project description:Non-specific protective effects against reinfection have been described following infection with Candida albicans. Here we show that mice defective in functional T and B lymphocytes were protected against reinfection with C. albicans in a monocyte-dependent manner. C. albicans and beta glucans induced functional programming of monocytes, leading to enhanced cytokine production in vivo and in vitro. The training required the beta glucan receptor dectin 1 and the non-canonical Raf 1 pathway. Monocyte training by beta-glucans was mediated by epigenetic mechanisms through genome-wide changes in histone trimethylation at H3K4. Pathway analysis showed specific induction of epigenetic changes in genes of innate immunity. The functional programming of monocytes, reminiscent of similar properties of NK cells, has been termed M-bM-^@M-^\trained immunityM-bM-^@M-^] and may be employed for the design of improved vaccination strategies. Chromatin-IP at day7 followed by highthroughput sequencing to look at the differences in H3K4me3 and H3K27me3 binding in Monocytes either cultured in RPMI only versus those trained for 24hrs with beta glucan. Additionally expression analysis was performed by doing strandspecific RNAseq also for both unstimulated and beta glucan trained monocytes for correlating the histone modification changes with the expression changes. Biological replicates were generated from independent samples for H3K4me3 and RNAseq. Additional H3K4me3 ChIP-seq assays were performed for day0 untreated, 24hrs control and beta glucan trained monocytes. H3K4me3 ChIP-seq was also performed for Mouse macrophages both saline(control) and low dose Candida treated.

RNA-seq of Dand5 KO and WT mESC

Project description:DAND5 is an extracellular protein belonging to the family of TGF-β/Nodal signaling antagonists Cerberus/DAN. Loss-of-function of DAND5 in mice leads to a massive increase of the ventricular heart wall’s thickness caused by an increased mitotic index of the CMs at the compact myocardium. To clarify the function of DAND5 in the molecular control of cardiomyogenesis, we carried out RNA-seq of a Dand5 KO mouse embryonic stem cell line (mESC) that proved to be a valuable in vitro cardiac differentiation model.

Characterization of the molecular interplay between Moraxella catarrhalis and human respiratory tract epithelial cells: Expression Moraxella catarrhalis strain BBH18 during adherence to human phanryngeal epithelial Detroit 562 cells

Project description:During the course of infection, respiratory pathogens like Moraxella catarrhalis needs to adhere to epithelial cells of different host niches such as the nasopharynx and lungs. Consequently, efficient adhesion to epithelial cells is considered an important virulence trait of M. catarrhalis. We examined the interaction between human pharyngeal epithelial Detroit 562 cells and M. catarrhalis BBH18 during adherence using a combination of Tn-seq, a genome-wide negative selection screenings technology, and expression profiling of both host and pathogen. The results described in this study are further discussed in Stefan P.W. de Vries, Marc J. Eleveld, Peter W.M. Hermans, Hester J. Bootsma: Characterization of the molecular interplay between Moraxella catarrhalis and human respiratory tract epithelial cells, submitted. After 1 hour adherence to Detroit 562 cells, RNA was isolated from adherent (n = 4) and non-adherent (planktonic) (n = 4) M. catarrhalis BBH18 as well as from bacteria incubated in the infection medium alone (n = 3). RNA obtained from the adherent fraction was enriched for bacterial RNA using the MICROBEnrich kit (Ambion). Total RNA was labeled according to standard Nimblegen gene expression array protocols and hybridized to a 4x72K Nimblegen M. catarrhalis expression array for read-out.
