Characterization of the small RNA content of Trypanosoma cruzi extracellular vesicles

Project description:A growing body of evidence in mammalian cells indicates that secreted vesicles can be used to mediate intercellular communication processes by transferring various bioactive molecules, including mRNAs and microRNAs. Based on these findings, we decided to analyze whether T. cruzi-derived extracellular vesicles contain RNA molecules and performed a deep sequencing and genome-wide analysis of a size-fractioned cDNA library (16M-bM-^@M-^S40 nt) from extracellular vesicles secreted by noninfective epimastigote and infective metacyclic trypomastigote forms. Our data show that the small RNAs contained in these extracellular vesicles originate from multiple sources, including tRNAs. In addition, our results reveal that the variety and expression of small RNAs are different between parasite stages, suggesting diverse functions. Taken together, these observations call attention to the potential regulatory functions that these RNAs might play once transferred between parasites and/or to mammalian host cells. Small RNAs profiles (16-40 nt) of epimastigote-derived extracellular vesicles, metacyclic trypomastigote-derived extracellular vesicles and metacyclic trypomastigote parental cells.

Characterization of tumor extracellular vesicle RNA cargo

Project description:Comparative RNA profiling between tumor cells and their secreted extracellular vesicles. Results revealed enrichment in genes involved in cellular migration and metastasis in extracellular vesicles, in agreement with their role as mediators of tumor progression. Mice were orthotoplically transplanted with MDA-MB-231 Breast Adenocarcinoma cells. Cells and extracellular vesicles (EVs) from the resulting tumors were isolated. EVs were characterized by electron microscopy and Nanoparticle Tracking Analysis before total RNA isolation for comparative analysis with cellular RNA. Three biological replicates were analyzed in (technical) duplicate.

sRNAs from Neisseria extracellular vesicles

Project description:Similar to bacterial proteins that are targeted to distinct macrophages organelles via extracellular vesicles, we propose that these vesicles also traffic small RNAs to modulate specific host factors. To test this, we aim to sequence extracellular vesicle derived sRNA, and whole bacterial small RNAs to determine selectivity, and to identify their bacterial and mammalian targets (Experimental Plan in Table-1). For this we will collect highly purified vesicles from N. gonorrhoeae (strain MS11A). We will also treat mouse derived primary macrophages with extracellular vesicles and compare their RNA response to untreated macrophages (Table-2). This will provide novel insights into how macrophages respond to N. gonorrhoeae infections. This data is part of a pre-publication release. For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/

Impact of Group Psychological Interventions on Extracellular Vesicles in People Who Had Cancer

Project description:Background: There is some evidence demonstrating the effect of psychological interventions in improvements in health biological parameters. To best of our knowledge, no study had addressed the impact of any psychological intervention on extracellular vesicles. In addition, Mindfulness-Based Cognitive Therapy (MBCT) and Emotion Focused Therapy for Cancer Recovery (EFT-CR) in the group have never been explored regarding extracellular vesicles and the effectiveness of these was not compared yet. Objectives: 1. To explore and compare the effect of MBCT and EFT-CR on biological parameters and psychological variables in distressed people who have had breast, prostate and colorectal cancer; 2. In addition, we will explore the acceptability through recruitment and retention rates of MBCT and EFT-CR in group and evaluate whether these interventions are appropriate for a larger clinical trial. Methods: The design of this study is a parallel randomized controlled trial. Participants will be randomized into MBCT, EFT-CR or usual care. Outcome measures will be assessed before, at the end of the intervention (8 weeks) and follow-ups (24 and 52 weeks from the baseline moment). Hypotheses: The researchers expected that both interventions will have an effect on extracellular vesicles and other study biomarkers as well as improvements in psychological outcomes, compared to treatment as usual (TAU) group. Regarding the comparative effectiveness, we did not have evidence to hypothesize which one of the interventions will be superior in both biological (extracellular vesicles) and psychological outcomes. Contribution for practice: The results of this preliminary study would permit to know if there are benefits of these psychological interventions on changes in extracellular vesicles and on psychological outcomes related to health. In addition, this study will permit to determine the acceptability of conducting a larger randomized controlled trial.
