Project description:Aims: To obtain small non-coding RNA expression profiles of short-term activated and long-term activated hepatic stellate cells (HSCs). To obtain small non-coding RNA expression profiles of small extracellular vesicles (sEVs) from short-term activated and long-term activated HSCs. Methods: Primary rat HSCs were isolated and cultured in vitro. To isolate HSC-derived sEVs, culture media (CMs) from Day 0 to Day 3 and Day 7 to Day 14 were collected. The sEVs from Day 0 to Day 3 HSC CMs were referred to as short-term activated HSC-sEVs (3dHSC-sEVs), and those from Day 7 to Day 14 HSC CMs were referred to as long-term activated HSC-sEVs (14dHSC-sEVs). Day 3 HSCs, Day 14 HSCs, and HSC-sEVs were collected and lysed in TRIzol (Life Technologies) for RNA sample preparation at the indicated time points.

Project description:Aim: To find out the effects of small extracellular vesicles (sEVs) from short-term activated and long-term activated hepatic stellate cells (HSCs) on Kupffer cells (KCs) and bone marrow-derived monocytes (MOs). Methods: For the isolation of HSC-derived sEVs, culture media (CMs) from Day 0 to Day 3 and Day 7 to Day 14 were collected. The sEVs from Day 0 to Day 3 HSC CMs were referred to as short-term activated HSC-sEVs (3dHSC-sEVs), and those from Day 7 to Day 14 HSC CMs were referred to as long-term activated HSC-sEVs (14dHSC-sEVs). Purified primary rat KCs and MOs were cocultured with 3dHSC- or 14dHSC-sEVs for 48 h. HSC-sEVs cocultured KCs or MOs were lysed in TRIzol (Life Technologies) for RNA sample preparation at the indicated time points.

Project description:Activation and migration of hepatic stellate cells (HSCs) followed by matrix deposition are characteristics of liver fibrosis. Several studies have shown the importance of hepatocyte and endothelial cell-derived extracellular vesicles (EVs) in liver pathobiology. However, less is known about the role of HSC-derived EVs in liver diseases. In this study, we investigated the molecules released through HSC-derived EVs and whether these can promote fibrosis.

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.

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.

Project description:We report the small RNA transcriptome of testicular extracellular vesicles in mouse testis. We established a testis dissociation protocol to isolate testicular extracellular vesicles. After treatment with proteinase K and RNase A, the RNA inside the extracellular vesicles was extracted and sequenced by small RNA-seq.

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.
